In an Ext Js-application I am working on I have a formpanel that contains (among other controls) three comboboxes, each with a different datastore. I need to load the form with existing data and display that in the form. This works for all simpel controls (textboxes, checkboxes) but there is a problem with the comboboxes.
The comboboxes each use a datastore but I can see that there is only one store loaded before the form loads its own data, causing that one combobox to display the correct text and the other two the value. If I click and close the combobox without making a selection the correct text appears.
Is there a way to either delay the loading of the form or the binding of the form until all datastores have loaded? The datastores are local stores with autoload and the formpanel calls its own load in the afterlayout-event.
The problem is that the setValue executed by loading your form is executed before the stores of the combo boxes are actually loaded.
You could try to implement the fix condor and animal of ExtJS have propsed in this forum thread on sencha.com: http://www.sencha.com/forum/showthread.php?75751-OPEN-42-ComboBox-s-setValue-call-with-a-remotely-loaded-Store
It basically just delays the setValue call on any combobox until the store of the combobox is fully loaded.
