Cannot set property 'component' of null

[GerhardV]

I have no idea where to start looking based on the following error message I receive when the page is loading. Also I do not get this with Version 1.0.0.1425.

 

"Cannot set property 'component' of null".

 

Nothing in the console...any ideas?

Does this happen in your working project?

[GerhardV]

Well not a commercial project, just a project I use to test and play with themes.

 

Loads fine in 1.0.0.1425 but not in 1.0.2.1444.

OK )

 

Can you make a simple testcase for this if possible?

OK I have tracked the culprit down by deleting components one by one. It was a TUniContainerPanel that had the following ExtEvents assigned:

 

function beforerender(sender, eOpts)

{

  sender.addClass("x-panel-container");

}

 

First I removed the event but the error persisted, then I cleared the cache but the error still persisted. Then I deleted the panel and the error was gone.  I then placed another TUniContainerPanel on the TabSheet and it still worked fine.

 

So I have no idea what the real problem was except for that it was that specific control....maybe some DFM corruption?
