Why appear as readonly?

[Former Member]

Hi, i´m doing an application, i create a new model, select Import Adaptative RFC Model, select the bapi function... After, i create a new view, i put an input field, in the propertie value select an attribute of the context. I execute the application and the input field appear as readonly, why?

Thanks,

[Former Member]

I find the solution.

I create a new element attribute in the context in customcontroller, and in the property value in searchview i write this attribute.

I delete all wddoinit in customcontroller, and in the method executeBapi_Material_Input:

public void executeBapi_Material_Input( )

{

//@@begin executeBapi_Material_Input()

Bapi_Material_Getbatches_Input input = new Bapi_Material_Getbatches_Input();

wdContext.nodeBapi_Material_Input().bind(input);

input.setMaterial(wdContext.currentContextElement().getValue1());

try {

wdContext.currentBapi_Material_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

} catch (Exception e) {

e.printStackTrace();

}

//@@end

}

Now work fine...

Thanks,

I see the problem, the problem is in this method:

public void wdDoInit()

{

//@@begin wdDoInit()

Bapi_Material_Getbatches_Input input = new Bapi_Material_Getbatches_Input();

wdContext.nodeBapi_Material_Input().bind(input);

<b> input.setMaterial(new String());</b>

//@@end

}

If i write previous appear the error, but if i write input.setMaterial("201311630A08000011"); work fine...

Hi,

U mean you can bind that variable with the UI element Inputfiled and send the value through screen then the output is comoing.

But here u are testing for single input valueonly.

when binding with Inputfiled MaterialNo then dynamically u can pass the value and write the execute method in the Action of the button.

then it will work.

thanks,

Lohi.

I don´t understand..... I don´t know very english....

What are you say me that change? I want that the value of the inputfield in the searchview find the values in sap/r3

[Former Member]

I do these steps:

I create an action, and in the method onActionSearch that it´s in SearchView:

public void onActionSearch(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionSearch(ServerEvent)

wdThis.wdGetJCOCustController().executeBapi_Material_Input();

//@@end

}

In the custom controller:

public void wdDoInit()

{

//@@begin wdDoInit()

Bapi_Material_Getbatches_Input input = new Bapi_Material_Getbatches_Input();

wdContext.nodeBapi_Material_Input().bind(input);

input.setMaterial(new String());

//@@end

}

public void executeBapi_Material_Input( )

{

//@@begin executeBapi_Material_Input()

try {

wdContext.currentBapi_Material_InputElement().modelObject().execute();

wdContext.nodeOutput().invalidate();

} catch (Exception e) {

e.printStackTrace();

}

//@@end

}

When i execute the application and write in the input, appear de previous error.

In SeacrhView, in layout, i click apply template... select form and after there is an attribute only... i select and create the label and the inputfield...

I rebuild the project, create archive and deploy...

I go to http://<server>:<port>/webdynpro/welcome and configure the application.

After execute the application, and the input is as readonly...

What happend?

In ResultView, in the context, i create a model node: Material, click in edit model binding and add only two attribute:

In SearchView and ResultView i add the JCOCust in properties.

In SearchView, in the context, i create a model node: Bapi_Material_Input, click in edit model binding and add only one attribute:

Project name: JCO

Application: JCOApp

Component: JCO

Custom Controller: JCOCust

Views:SearchView and ResultView

Create Model:

Import Adaptative RFC Model, Name: MaterialModel, package: com.sap.model, model instance: WD_MATERIAL_MODELDATA_DEST, RFC metadata: WD_MATERIAL_RFC_METADATA_DEST. I connect with R3 and select the bapi: BAPI_MATERIAL_GETBATCHES and finish.

In the component select used models and add the model MaterialModel.

In the JCOCust, in context --> new model node Bapi_Material_Input. After, edit Model Binding, select Bapi_Material_Getbatches_Input and select (in the image):

Hi Victor,

Why are you creating a new model node in JCOCust. Just goto navigation modeler and map the model context to the model context.

This is my model:

<a href="http://img462.imageshack.us/my.php?image=diagrambw4.jpg" target="_blank"><img src="http://img462.imageshack.us/img462/3435/diagrambw4.th.jpg" border="0"/></a>

Is it wrong? Delete de model node in custom controller? How map it?

Victor,

In NWDS, Right Click on your Component Name and select Open Data Modeler

Select create a delta link in the selection tool bar on the left and strech it from controller to your model. Now it will ask you to map the nodes and attributes. Select the input model node and now the same node structure would be available in your controller.

Similarly now map from controller to view.

Murtuza

[Former Member]

Sorry, i don´t undertand... I don´t know very english...

Are you see my image? Delete all datalinks? You say that i create a datalink between SearchView and Used Model or Custom Controller?

[Former Member]

Victor,

Data link between your model and controller and then between controller and view.

Sorry, but your image is blocked here and I won't be able to have a look at it.

Murtuza

[Former Member]

Now i have something very strange. I have data link:

- SearchView and CustomController

- SearchView and UsedModel

- ResultView and CustomController

- ResultView and UsedModel

- CustomController and UsedModel

Delete all and create:

- CustomController and UsedModel

- SearchView and CustomController

- ResultView and CustomController

Ok?

Thanks,

[Former Member]

Yes victor,

you are going right now.

<b>Delete all and create:

Ok, now i can write in the inputfield, but when i press search appear this error:

Don´t work... Now i write all my steps... I delete the project and i write all steps...

[Former Member]

I put a new image:

<a href="http://img221.imageshack.us/my.php?image=aplicacion2ho5.jpg" target="_blank">!http://img221.imageshack.us/img221/3262/aplicacion2ho5.th.jpg|alt=Free Image Hosting at www.ImageShack.us|src=http://img221.imageshack.us/img221/3262/aplicacion2ho5.th.jpg|border=0!</a>

I think that it´s all good... no?

In the custom controller i have:

public void wdDoInit()

{

//@@begin wdDoInit()

Bapi_Material_Getbatches_Input input = new Bapi_Material_Getbatches_Input();

wdContext.nodeJco_input().bind(input);

input.setMaterial(new String());

//@@end

}

All correct? It continues without working

[Former Member]

Hi Victor,

Add this line:

wdContext.nodejco_input.addElement(input);

Regards,

Murtuza

[Former Member]

public void wdDoInit() 
{ 
//@@begin wdDoInit() 
Bapi_Material_Getbatches_Input input = new Bapi_Material_Getbatches_Input(); 
wdContext.nodeJco_input().bind(input); 
input.setMaterial(new String()); 
wdContext.nodeJco_input().addElement(input); // add this line 
//@@end 
}

Where?

[Former Member]

Appear an error that say: addElement(IWDNodeElement) in the type Node is not applicable for the arguments (Bapi_Material_GetBatches_Input)...

I change the cardinality too and don´t work...

Hey Capi,

Follow these steps.

In your custom /Component controller u defined your modenodes from your Model.

Then in the init method of the custom/component controller u add the following code.

Wddo init()

{

BAPI_Material_GetBatches()_input input = new BAPI_Material_GetBatches_Input();

wdContext.nodeBAPI_Material_GetBatches_input().bind(input);

input.setMaterialNo("10000"); //here hard code the value

try{

Wdcontext.currentBAPI_Material_GetBatches_inputElement().ModelObject().execute();

Wdcontext.nodeOutput().invalidate();

}

catch(Exception)

{

e.printstacktrace());

}

}

In the output node u have any of node contains output table that create as first View with talbe binding with your outputnode.

it might helps you.

Try this code in your end mi

Thanks,

Lohi

Error, say that the method currentBAPI_Material_GetBatches_inputElement() is undefined for the type IPublicJcocust.IContextNode...

[Former Member]

try these

wdContext.nodeJco_input().addElement(wdContext.createJco_input());

wdContext.nodeBapi_Material_GetBatches_Input().bind(new nodeBapi_Material_GetBatches_Input());

but where? In the controller custom or in the view?

[Former Member]

Hi Victor,

Write this:

Hi,

Expand your component controller context I mean allnodes and nodeelements needs to be displayed in the screen shot.

show me once such that I will give you the solution.

<b>I am not able to open your image Send that componentsontrollercontext screen shot </b>

Hi Victor,

There are 2 options:

1. Change the cardinality of the input node to 1:n from 0:n

2. Instantiate an input node element in wdDoInit()

<bapi_inputnode> ele = new <bapi_inputnode>();

wdContext.node<bapi_inputnode>().addElement(ele);

[Former Member]

Hi

if you are binding your elements with a node of your context say " MyNode "

import like this

import yourpackage.IPrivateYourView;

import yourpackage.IPrivateYourView.IMyNodeElement;

and

in your WdDoint()

I<MyNode>Element node=wdContext.create<MyNodeElement>

node.set<MyElement1>()="";

node.set<MyElement2>()="";

wdContext.node<MyNode>.addElement(node);

The node of my context say jco_input, but when i go to implementation in the view... when i write import com.sap.pruebas.jco.wdp.IPrivateJCOView.Ijco_inputElement;

Appear an error, not exist Ijco_inputElement... not existe nothing when y press cr+space in IPrivateJCOView...

[Former Member]

Hi Victor

Don type that import statement

first write the code in the<i> wdDoinit()</i> and finally use <b>ORGANISE IMPORTS</b> option it will be automatically add that import statement

Regards

Chaitanya.A

[Former Member]

I write this:

Ijco_inputElement node = wdContext.createjco_inputElement

node.setMaterial();// ex to set name node.setName("HI");

wdContext.nodejco_input.addElement(node);

The model node in context is jco_input and the model attribute in model node is material.

The inputfield is material... Is the previous code good?

Thanks,

[Former Member]

Hi,

U need to instantiate the BAPI in your WDdoinit() method of your first screen ro Component/custom controller.

For suppose your FNM name is BAPI_FLIGHTLIST

BAPI_FLIGHTLIST input = new BAPI_FLIGHTLIST();

wdcontext.nodeBAPI_FLIGHTLIST().bind(input);

And bind the currect Value attribute to UI element.

Then it should be visible.

Thanks,

Lohi.

HI

have you added the element to the node

are you Using <b>Component Cotroller Node</b> --> <b>Apply Template</b> --><b>Form</b> (Wizard)

in this case you need to manually add the element to the node,like

I<your node name>Element node=wdContext.create<your node name>Element
node.set<yout attribue>();
wdContext.node<your node name>.addElement(node);

Regards

Chaitanya.A

[Former Member]

In rootUIElementContainer i select apply template, select form, select the attribute of the context (there is one only), and appear the label and the input correct. I execute the application and appear as readonly...

[Former Member]

then use this code

I<your node name>Element <b>node</b>=wdContext.create<your node name>Element
node.set<yout attribue>();// ex to set name node.setName("HI");
wdContext.node<your node name>.addElement(node);

Regards

Chaitanya.A

Hi,

If the model context is null then the input field will be readonly.

For example if you have a model node as Data and inside that there is a context say Name. Then unless the node Data is populated with values and Name cotains value, the UI element which is bound with Name will be readonly.
