Gabriel Gruber commented on COCOON-1738:
----------------------------------------

I attached 2 patches which worked for me to use the DoubleListBox within an Ajax enabled CForm under Cocoon 2.1.10.  With this path the DoubleListbox works with Ajax (outside of a repeapter!)

I recently tested them also inside repeaters, with mixed results.
I think it is a starting point, how the problem could be solved :-)

> Rendering a multivaluefield using the 'double-listbox' styling fails, when that multivaluefield is contained in a repeater, and Ajax is enabled for the form:
> The 'double-listbox'-styled fields in the repeater stop working as soon as some action, involving a round-trip to the server and a partial re-rendering of the repeater, is being performed (for example adding or deleting a repeater row, validation error on submit...)
> After such a round-trip, a click on any of the double-listbox's UI elements (double-click on an item, click on an option-transfer button) will yield a Javascript error ("optxxxxx is not defined" on Cocoon 2.1.8, and "from.options has no properties" on the current BRANCH_2_1_X)
> The multivaluefield's values will not be submitted correctly afterwards.
