[solved]automatic expand combobox in grid

[Spirit]

I know this has been discussed a few times but i found no contribution where it works.

I tried 2 approaches:

First i tried to add an listener to my grid:

		listeners: { 
		   	celldblclick: function(o, row, cell, e) {
		      	o.getColumnModel().getCellEditor( cell, row).field.expand();
	     },

The editor is a Ext.form.ComboBox, so i thought this should work but it does not.

My second approach:
I added an listener to my editor (Ext.form.ComboBox), so i could expand my combobox when it gets focus. Again there is no problem of catching the desired event but if i try to expand
the combobox i get the following error:
>>this.list has no properties

I dunno why i get this error. The store of my combobox is autoloaded, so i m pretty sure the list should exist. I tried playin around with mode, lazyRender and loaded the store explicitly but noting helps.

[CODE]
var storestatusrg = new Ext.data.JsonStore({
url: 'rgcbs.php',
baseParams:{typ:'status',langid:1},
root: 'items',
fields: ['id', 'name'],
autoLoad:true
})


cbtyprg = new Ext.form.ComboBox({
storetoretyprg,
triggerAction: 'all',
emptyText:'Bitte w

...i know everyone is reading the licensing threat so nobody has time... but ... can someone point me in the right direction.

Configure your combobox with a focus listener which calls onTriggerClick

Thats what i did in the second example above. And i get an error:
this.list has no properties

See above :/

You need to set scope.

What do you think "this" is going to be inside that function?

Hmmm... has nothing to do with scope this time... or i am i totally wrong ?

[CODE]
cbtyprg = new Ext.form.ComboBox({
storetoretyprg,
triggerAction: 'all',
emptyText:'Bitte w
