Hello all,

 

I am working in adding a dynamic component to a vf page that loads a field set and some other stuff into a page section at the bottom of the mentioned VF page. The idea is that when the user focuses on a picklist field that is part of a row of records displayed in a pageblock table, the dynamic component should update with the correct set of field sets on a pageblocksection below the table. The thing is that it is not doing this because I cannot ge tthe current record id (the row in the table where the user is focusing) to be passed to the controller and therefore it is getting NULL Since the code in the controller has a validation to return null IF hte current record is null, nothing is happening. Yet if I perform changes to other fields on the row the record id is passed just fine back to the controller. can someone assist! Below is the VF page, the controller nad the debug result, where I highlight the relevant parts.

 

Thanks!
