Mapping with dropdown component

[Former Member]

Hi,

I have a view with a dropdownbyIndex component. The entries available in the dropdown list are comming from a bapi result.

In order to do this, the property "texts" of the compopnent is pointing to a model attribute of my context which is mapped to my custom controler .

This works fine and when executing I see all possible values coming from my bapi.

Now the problem is that I need to get the selected value of the list to be an input parameter for another bapi I import in my model.

How to do this ?

My view context have a node "MyList" and under this a property "MyProp" but it is already bound in my custom controler to the bapi_input that get the list to display.

If I try to set manually the bapi_input (wdContext.myNode.currentElement.setMyProp("toto")), a null pointer exception occurs at runtime.

Thanks,

Sylvain

Hi,

Consider you want to send the selcted value to another modelNode with following structure.

Model2

Input

AttrInput

wdContext.nodeModel2().bind(new Model2());

wdcontext.currentInputElement().setAttrInput( wdContext.OldOutputNodeElement().getValue());

now use execute method on Model2 node.

hi

suppose your dropdownindex is bound toan attribute 'droptext'which is under node 'dropnode'.

now you can set the bapi input manually as

wdContext.myNode.currentmyNodeElement.setMyProp(wdcontext.nodedropnode.currentdropelement.getdroptext());

now exceute your bapi.

hope it works.

Hi,

Thanks for your answers.

I solved my problem using :

	Bapisditm items = new Bapisditm(); 
	items.setMaterial(wdContext.nodeArticle().currentArticleElement().getMatnr());
	inputPO.addOrder_Items_In(items);

The problem was coming from the fact that the bapi was requiring input tables.

Hi Sylvain,

Nice to hear that you have solved the problem.

So, please close this thread.

Hi Sylvain,

I am geussing that you have not instantiated your bapi_input node before setting the value.

Can you give me your BAPI structure for both.

And how you are passing value from the list to the another BAPI?
