fails now in 5.4

Posted by Chris Poulsen <ma...@nesluop.dk>.

I think my first suggestion would have worked if you had actually wrapped
the select in a t:zone and not a <zone> tag and removed the argument from
the handler... as i wrote there is no need to work with hidden submits etc.
it works right out of the box, with dead simple code.

your pasted code is a mess. But from what I can see your attempt to
implement my suggestion was almost correct... except that you had an
argument in your change handler:

was:
  onActionFromItemsPerPageSelect(Integer value)

should be:
  onActionFromItemsPerPageSelect()   [the property bound to the value of
the select component has the newly selected value when this is triggered]

RE: fails now in 5.4

I dont want to add a submit button because its not natural for a gallery with a select 		 	   		  
thats why I put the
    onchange="galleryForm.submit()"
because when I omit that nothing gets triggered to this code for anything
The gallery needs to redraw but no event is being triggered and persistent properties are locked down
any further ideas are very much appreciated... I have spent a long time on this onecant shake it out

dont mess around with the form manually - you cannot submit it using that
function - instead wrap the select in a zone and specify zone="^" on the
select.
