Hi all,

I'm working with MultiCombox - https://examples2.ext.net/#/Form/ComboBox/MultiCombo/ and I get the following issue : I cannot set Raw Value for MultiCombox while keep the selected items be unchanged. Here is my step :

Navigate to https://examples2.ext.net/Examples/F...ox/MultiCombo/ - well, it's much easier for testing in an offical page of ext.net, no need for creating a test project.

1. Expand the list of items in first Combobox - Simple MultiCombo
2. Using Developer Tool of Internet Explorer, set the Browser Mode to IE 8 and Document Mode to IE 8 standards.
3. On the "Console" window of Script tab , run the following script : 
this.App.ctl05.selectAll(); 
this.App.ctl05.setRawValue('All');
4. My expectation is : the Raw Value of Combobox change to 'All' , and the selected items is keep . But only the raw value be set, while all items are unchecked.

This only caused in IE 7, 8 ( I think we can set out of mind the older version ) . In firefox and IE 9, it works fine.

I suggest that this's features of ext.net control , so anyone can guide a workaround for this case ? Thanks a lot.
