javascript - Dynamically setting multiSelect for combobox in extJS -

-

i kinda facing interesting problem combobox's multiselect property.

i have grid 3 columns id, name, associated part.

i have enabled rowediting plugin , editors id textfield(editid), name textfield(editname) , associated part combobox(editpartcombo multiselect true).

i have 2 buttons add , update.

when select row in grid , press update, rowediting starts @ exact position. in update button code, setting multiselect property of editpartcombo false somehow not reflecting.

code on update button:

{ text: 'update press',  handler: function(btn){  var grid = btn.up('grid'); var selection = grid.getselectionmodel().getselection();   if(selection.length > 0){  combo = ext.getcmp('editpartcombo'); combo.multiselect = false; delete combo.picker; combo.createpicker(); combo.reset();  var rowediting = grid.getplugin('roweditplugin'); var rowno = grid.store.indexof(selection[0]); rowediting.canceledit();  rowediting.startedit(rowno, 1);   }  else{ ext.msg.alert('error' , 'please select row update'); }   }

in firebug when inspect combo - shows multiselect false still able select multiple values.

not sure doing wrong?

please help.

thanks in advance.

if cange config value after component created, not guaranteed value applied. config option, , other doesn't work.

i recommend ext.create combobox, , inject multiselect configuration @ time. 1 button create multiselect enabled, , disabled other.
