Table Sort Deleting Inner Node Content

Hi guys,

I have a node inside a node, and I'm displaying them using Table UI elements. The inner node/table is shown within a Cell Popin.

When I sort (IF_WD_TABLE_METHOD_HNDL-APPLY_SORTING) the outer table, the content of the inner table is being deleted.

Is there a way to avoid this or do I need to create a custom Sort?

Regards,

Raúl
