Tab Panel issue extjs 4.07

[dbloom]

1) I am using the ext.Tab.Panel and sucessfully create two tabs using the API as follows:


this.add(tab);
this.setActiveTab(tab);




2) However, I programatically close the second tab :


this.remove(cards[i], true);


3) When i perform the click to create the second tab like I did in step 1 again:


Uncaught TypeError: Cannot read property 'style' of undefined


Line 14768 in ext-debug.js

It happens on ie,chrome, and firefox.

Any HELP on why I am experiencing this problem?

Considering that its the second time through with the same tab, it has me puzzled.

As far as my specific scenario, its is essentially this example found here
