Using UI Element Input Field

[Former Member]

Hi,

I have created two views.In the first view I have created a input field and attached that to Model attribute inside model node.

Created a model and then binded the model with the context of controller.Then binded the controller context with my view context.

When I see the output I am getting the input field as disabled.

Should I do any thing more.

Regards,

Suraj.

This could be because of 2 things

1. You have not created an instance of the modelclass and bound it to the context at runtime.

2. The model attribute maybe readonly.

But I think (1) is mostly the case here.

Hi Suraj,

What Mukesh said is right.

As per the senario, you have a view controller's context structure as:

-BAPI_NODE

- OUTPUT_NODE

- INPUT_ATTRIBUTE

and you are trying to bind the input field directly to the INPUT_ATTRIBUTE. This makes your input field greyed out/read only.

All you have to do is, create another attribute called "USER" for example under the comp. controller's root node. Map it to your view controller. Bind this to your Input field.

In your component controller's implementation code where you execute your BAPI you will have code like this:

(1) BAPI_NODE input = new BAPI_NODE();

(2) wdContext.nodeBAPI_NODE().bind(input);

(3) try {

(4) input.execute();

(5) } catch (Exception e) {

(6) e.printStackTrace();

(7) }

Please add the following code in between (2) and (3).

input.setINPUT_ATTRIBUTE(wdContext.currentContextElement().getUSER);

Change the cardinality of the BAPI_NODE back to 0:n.

Try to execute your code. It should work fine now.

Hi Suraj,

1. Bind the input with other context attribute

2. assign the model input values from the context attribute.

wdContext.current<BapiNodeInput>Element.set<Param>(wdContext.current<node>Element.get<Param>());

and check the cardinality of <node> is 1..1 or 0..1

Kind Regards

Hi Suraj,

You have to instantiate model class and bind it to context node first. Your model node doesn`t contain any elements. That`s the reason why input fields are disabled.

Hi,

Change the node cardinality of the Model node you have mapped the input feild to; equal to 1:n.

It would have been 0:n, I guess.

OR

In the wdDoInit() function crete and element of that model node.

wdContext.node<Model_Node>.createAndAddElement();

I hope this will solve your problem
