Creating Dynamic UI Elements in Web Dynpro ABAP

[Former Member]

Hi,

I want to an application in which the context nodes and the UI Elements for the second screen get created dynamically at run time based on the input on the first screen

First i have used this method :

cl_wd_dynamic_tool=>create_nodeinfo_from_struct()

to create the dynamic context nodes.

I have checked in debugger and the dynamic context node is getting creates successfully.

I have saved the reference for the context node in DYN_NODE.

Now for creating the dynamic UI Elements corresponding to the attributes of this context node, i call the method :

cl_wd_dynamic_tool=>create_form_from_node(

ui_parent = group_1

node = dyn_node

inputlength = 20 ).

But this thing is dumping.

This is the dump.

The following error text was processed in the system CG7 : Adapter error in &VIEW_ELEMENT_TYPE& "BP_ICLIENT" of view "ZWD_ONLINE_FORMS.FINAL_VIEW": Context binding of property VALUE cannot be resolved: Node FINAL_VIEW.1.BP does not contain any elements

Where BP_ICLIENT is the first attribute of the dynmaic context node BP created..

Please Help.

Thanks

Shivi
