Hi,

To pass objects from one view to another view is simplest way is set the objects into session(HTTPSession) and retrieve it from another view. Steps are given below.....................

Step 01: Add J2EE.jar file into classpathe of your webdynpro application as add external jar.

Step 02: Create session(HTTTPSession) object.

Step 03: Store objects into session as setAttribute.

Step 04: Retrieve objects from session from another view.

Hi Shanto,

Which version of NetWeaver r u using? If u r using 04s/7.0.x , u can use a collection for that. Create an context attribute of type ArrayList(or any other collection) & using context mapping, u can pass the values.

hai sumitha,

Can you provide the coding to store the values in arraylist.

I cant see the point on using webdynpro if you dont take advantage of attribute mapping.

And for the array-list issue, use Array.asList(Object[]), reverse would be List.toArray().

Thats what contexts mapping/bindings are for. Just create an attribute in controller context, of that array type, and map it to both of those views.

When you change the value on one of these contexts, it will change on the others too, mapped attributes share values because they share the same instance.

Hi,

What kind of array?

Instead use the attribute inside a node and map it to both the views using controller.

Now you have array of values in both the views.

thanks & regards,
