Same problem here -- my workaround is to show the tree expanded by default. Yet that doesn't solve the issue with the arrows...

Basically the combobox sees a "blur" event when clicking on the tree and thus collapses. But I don't know how to prevent that.

By the way, if someone had a fully working "combobox + tree" solution for ExtJS, that would be very helpful. Because the solution provided on the Sencha forums is quite limited:

• Display and value of the combobox has to be the same (whereas I'd like its value to be the tree's node ID)
• There's no way to "restore" the value/display of the combobox when it's part of a form (e.g. using "form.loadRecord()")
