Question on POWL

I have a POWL where I have a cell based action. It is a hyperlink. When the user clicks on this link a web dynpro application opens displaying more info about that row.

Everything works fine as it is. But when the user sorts the result table based on another column and then clicks on the hyperlink the old values are taken.

So lets say the table had four records initially

Col1     Col2

A             x

B             z

C            y

D           w

Now after sorting on Col2 the tables look like below

Col1     Col2

D           w

A           x

C          y

B          z

Now when the user clicks on A(this is a hyperlink), B gets opened.

This is happening because in the feeder class c_result_tab is not updated after sorting and we read based on index. In this case indes is 2 which is right. So B gets read instead of A.

Any ideas??
