View Full Version : Multiple tabs disappear

25 Apr 2012, 7:37 AM

I have multiple tabs (w/ unique id) built on ext-4.0 and since then any extjs release (now extjs 4.1) cause multiple tabs disappearing all together when I close one tab.

I get this error on firebug using ext-all-debug-w-comments.js

Uncaught TypeError: Cannot read property 'parentNode' of undefined

Does anyone know any solution for this?

Are you creating the id's yourself? If you remove them (for testing), does it make a difference?
Do you see the problem, or can you duplicate this using:

Apparently the problem was with grid in each tab. I had a column with an "id" which creating duplicate "id". So, when I close a tab, it close all tabs with grid that has same "id" in the column.

Well...sometime problem does not always reflect what firebug indicates, it could be somewhere else.

Hi austin1030,

I run into the exact same problem with my dynamically added tab panels in Ext JS 4.1. In Ext JS 4.0.7 it all all fine. I tried to come up with a workaround but failed. Could you tell me in more detail how you resolved this.

Your problem with the id column extends to any component with duplicate id contained in another tab panel. In my case I had a toolbar on the grid in the tab. Inside the toolbar I had a button with a duplicate id. Eliminating this id resolved the problem. Took me a long time to figure that out.
