How to save changes in a Table?

Hi Experts,

I have included my own component into an SAP component as an assigment block. My component shows a table (Table Context Node). I have made some columns editable. However, when I try to make changes in this table, after pushing the Enter Button, the chaged values is being replaced by the old value.

I have set

rv_disabled = 'FALSE'.

in my GET_I_<attribute name> method. I guess there are other things to do..?

How can I make and save changes in my table?

Thanks, Johannes
