Hi,
I'm just wrapping everything up to be able to mark this thread as answered. In the end content selection by double-clicking table cells is not supported by SAP, and you have two options to enable this feature:
- Refactor the whole component logic to switch to frontend selection mode (see note 1318610 provided by Jean-Yves in one of the comments)
- Disable the rowselectionbylineclick via a customer modification in javascript file scripts_.oo_tableview.js. But becareful: the latter will make it impossible to select a line in a table in case no row-selector is provided (we saw that happen in some tree views for example).
Cheers,
Nick.
