View Full Version : Uncaught TypeError: Cannot call method 'call' of undefined when removing tab panel

When I click the X of a closable tab panel it doesnt close, but instead yields this error Uncaught TypeError: Cannot call method 'call' of undefined . The second time it closes. Any ideas?

In which version of ExtJS are you seeing this? Are you listening to any events that might be firing when you close the tab? What kind of content is on the panel being closed?

Extjs 4.2.1 I also tested with 4.1.1, the main content is always a panel. I suspected a callback but I disabled them last night and still had the issue. I am going to dig a bit further today.

Looks like it has something to do with the Portal I am using from the demo. I am still investigating.
