WD - dump after clicking on screen - Binding

[former_member246634]

Hi Experts,

On my screen I have two containers displaying ALV with the same data: one (older) has TABLE type, the other (new) is ViewContainerUIElement.

My initial goal was to replace the old container with the new one, but since it's not working fine I can see what happens with both of them.

I have created a method SET_TABLE_CONFIG, which is called in another method MODIFY_SCR:

method SET_TABLE_CONFIG .

This is what happens after starting an application:

1. Both ALV's are displayed, but the in new one (ViewContainerUIElement) there aren't editable fields (but there should be).

2. After pressing on column header of the new container I get a dump:

The exception 'CX_WDR_ADAPTER_EXCEPTION' was raised, but it was not caught
 anywhere along
the call hierarchy.


Since exceptions represent error situations and this error was not
adequately responded to, the running ABAP program
 'CX_WDR_ADAPTER_EXCEPTION======CP' has to be
terminated.



An exception occurred which is explained in detail below.
The exception, which is assigned to class 'CX_WDR_ADAPTER_EXCEPTION', was not
 caught and
therefore caused a runtime error.
The reason for the exception is:
Error in TABLE "CONT_DOCS" of view "ZWD_LT_PROCESS.ZWD_LT_CREATE": Context
binding of property ? cannot be resolved: Wybór potencjalnej szansy nie jest
ustawiony w węźle kontekstu ZWD_LT_CREATE.1.LT_DOCS


The occurrence of the exception is closely related to the occurrence of
a previous exception "CX_WD_CONTEXT", which was raised in the program
 "CL_WDR_CONTEXT_NODE===========CP",
specifically in line 11 of the (include) program
 "CL_WDR_CONTEXT_NODE===========CM00V".

The thing is I have no idea why it has a problem with button properties binding. Everything was fine before I added ViewContainerUIElement and SET_TABLE_CONFIG method and now I have no idea what to do.

I'd be very thankful for any help

I've found solution for this dump myself. All I had to do was to delete standard container:

After that sorting works fine (before after clicking on header I got that dump).

No my problem is that none of the fields are editable, but some should be.

I'd be grateful for aby help
