ContextAttribute Result has JavaNative Type ArrayList

[Former Member]

Hi,

I created a model by importing from webservice. The webservice has a method which return an object of type ArrayList.

Now my problem is that I can't bind this to my table in webdynpro Iview.

I get the following message.

ContextAttribute Result has JavaNative Type ArrayList

ContextAttribute with java native type cannot be selected

There are other option we can achieve it, but what i want is to bind the arraylist with some concept of array of objects.

Thanks and regards,

Hi,

I feel the issue which i am facing is not being analyzed properly. I need to bind the context attribute to an arraylist. How can we do it...

Hi Sameer,

Take a context attribute say xyz of type <b>java.util.ArrayList</b>

Default Context Attribute type is string. Go to the property window then browse

Type Value. Select Java Native Type: java.util.ArrayList

ArrayList arr = new ArrayList();
 arr.add("Hello");
 arr.add("World");
	
wdContext.currentContextElement().setXyz(arr); // Binding ArrayList to a context Attribute
	
wdContext.nodeTest().bind(arr); //Binding ArrayList to a context Node

instead of <b>arr</b> Set the ArrayList object that you are getting from the Web service Method;

Hi Sameer, in your case you will have to iterate that ArrayList, extracting its elements one at the time, casting them to an appropiate ValueObject type, then extract its data attributes and populate your table with them.
