Error Data no longer available when SALV_WD_TABLE GET_MODEL called

Question

Hello ,
I have dynpro component on ECC6.0  POWL_UI_COMP which displayes service oders.
This dynpro component has one more component usage component POWL_TABLE_COMP.
This POWL_TABLE_COMP has used a SALV_WD_TABLE which is for ALV display.
I have to create a on ALV toolbar one button,I know that I have to do this using self defined functions in wddoinit method of
view which uses SALV_WD_TABLE and i could generate a button using self defined fucntions for another dynpro component.
Now I am trying same method for this POWL_TABLE_COMP dynpro which is using SALV_WD_TABle , but its giving error as this
Data no longer available when SALV_WD_TABLE GET_MODEL called .

Hi Sharada ,
I had the same error message.
To resolve the problem I had to bind the context again to the interface controller of the used component.
