Storing collection of values in Web Dynpro

Question

Hi,
I have 2 views(View1,View2)
I have rows of 2 dropdowns in a table in View1. I select each of these drop downs in multiple rows and go to view 2. In View2 i need to retrieve all the values from View1. How will i retrieve these values?
Is there any collection kind of thing in Web dynpro??

Hi,
   Let's say you have a context structure as this:
-Root
--TableProperties
---Column1(value attribute bound to your 1st dropdown)
---Column2(value attribute bound to your 2nd dropdown)
   Have a context node structure as
-Root
--DataNode
---Value1(value attribute, String)
---Value2(value attribute, String)
Map this to the component controller's context with the same structure.
In the onSelect eventhandler, write something like this:
IPrivate<view name>.IDataNodeElement elem = (IPrivateSDNCompView.IDataNodeElement)wdContext.nodeDataNode().getElementAt(wdContext.nodeTableProperties().getLeadSelection());
if(elem != null){
elem.setValue1(wdContext.nodeTableProperties().currentTablePropertiesElement().getColumn1());
elem.setValue2(wdContext.nodeTableProperties().currentTablePropertiesElement().getColumn2());
else{
IPrivate<view name>.IDataNodeElement ele = wdContext.nodeDataNode().createDataNodeElement();
elem.setValue1(wdContext.nodeTableProperties().currentTablePropertiesElement().getColumn1());
elem.setValue2(wdContext.nodeTableProperties().currentTablePropertiesElement().getColumn2());
wdContext.nodeDataNode().addElement(ele);
Add component controller as required controller in view2.
Now from view2, you can access it as
wdThis.wdGet<component name>Controller().wdGetContext().nodeDataNode();
