Still i have a problem with sending data to backend through inputfiled

[Former Member]

Hi all,

I have still problem with Input Field. Context and model binding and backend every thing is fine. I created action in view to execute the model. And also created method in Controller. Every thing seems ok. Why this input field is grade off, can not enter data in view. any idea?

I tried all my possible ways. Any idea?

Thankx

hi,

create element of model classes, and bind them to UI field,

put code for creating elements in init().

I found the problem, it is problem in backend table. Here we are using structure instead of attribute.

Hi,

Check your bindign withe that input field that would be the problem.

dont need to set the cardinality when you are using model node.

Hi ravi,

Assume the below layout to be your context layout

NodeA

... Attribute1

Suppose Attribute1 is the context element that is bind to your inputField in the view.

In wDoInit() method of the component/custom controller

//create a instance of your model

SampleModel model = new SampleModel();

NodeA Req = new NodeA(model);

wdContext.nodeNodeA.bind(req);

This should enable the inputfield.

In the custom controller wdDoInit() method , you have to create and bind your model object instance into the corresponding node

for ex:

Bapi_Salesorder_Getlist_Input inp = new Bapi_Salesorder_Getlist_Input();

wdContext.nodeBAPI_SALESORDER_GETLIST_INPUT().bind(inp);

thanks

Hi Ravi,

• Please check Your Binding and Mappings

• Try to set the value for that Context Attribute.

• Consider that you have a InputField . U have bound a context(Val) attribute with that Input field. write the code to set the value,

wdcontext.getContext.currentContextElement.setVal(""); //Empty value

(or)

<You model node>.setVal(" ");

(or)

<You model node>.setVal(Object);

hi

Instantiate your model class and bind it to your model node bound to the i/p field in your init of the controller. it will work. Thanks.

Hi Ravi,

I think because of cardinality of the model node, input field is blank.

If the cardinality is 0..n, then by default input field will be blank as there is no instance of the node.

If u change it to 1..n, by default webdynpro creates an instance of this node. If u can't change the property then u need to manually create an instance and bind that object to the node.

Thanks.
