问题 I am trying to set up a multiselect item selector based on this sencha example code. However, after building it into my environment, I get this error: What could be causing this error and how might I fix it? Addendum I have found that when I comment out this line: //xtype: 'itemselector', then it works. Why would the xtype "itemselector" not work? Strange also that I have found this list of valid ExtJS xtypes and itemselector is not on it. How could the Sencha example work if "itemselector"

问题 In the project I'm working on, I have forms I sometimes have to fill by code. Let's say I have two comboboxes : combo1 and combo2. They are both required by default (allowBlank : false). On combo1's select event, I set combo2's allowBlank property to true and clear it. Everything's good so far, while user is filling the form. When I use combo1's setValue method, it doesn't trigger the select event, so combo2 is still required when I don't want it to be. What is a good way to solve this

问题 In this sample Ext Js grid: http://dev.sencha.com/deploy/ext-4.0.2a/examples/dd/dnd_grid_to_grid.html You can drag and drop items from one grid to another, but you can't change the order of items in the second grid. You can drop items back and forth and order them the way you wish, but that's not an elegant way of doing it.
