The update method of any container doesn't work in IE
Dear Support team,
I ran into issue, the update method of any container throws a java-script error in any version of IE. The same code works well in any other browser.
Also, I found that the issue exists only in the version 2 of Ext.Net. The same code works well in version 1 and 3.
My version of Ext.net is "2.5.2" (Pro License)
Here is the sample code:
This issue can be reproduced even on the examples page.
You can see comparison of the different versions behavior on this video:
I found the comment in the code, near the block that throws exception: "core/layout/Field.js" This may help to find the problem faster.
I can be wrong, but here is my assumption about the cause of this issue:
It seems like this issue exists for all type of containers which contain any descendants of type Field (text field, combo box, date field etc).
Error appears in the code where Ext.Net overrides the layout behavior of Field type. When container is updated it recreates its contents. When one line of code is reached in Chrome the markup is already recreated, but in IE the DOM contents of the panel is empty.
The JS engine can't find a parent of the indicator element because at this moment there is no any markup inside of the panel (neither indicator cell, nor main component cell).
Hope you can help,
Sander
