'headerCt' is null or not an object Error

[EvilKnight]

REQUIRED INFORMATION


Ext version tested:

• Ext 4.1.0

Browser versions tested against:

• IE8

Description:

• Under ext-all-dev.js, under line 121695.
• 'headerCt' is null or not an object Error

Steps to reproduce the problem:

• Having 2 tab item in the Tab Panel.
• 1st Tab let it be empty tab.
• 2nd Tab create a Grid Panel and render record together with Selection Model(CheckBox).
• When load, select the Checkbox accordingly.

The result that was expected:

• Should select the Checkbox without prompting error.

The result that occurs instead:

• 'headerCt' is null or not an object Error

HELPFUL INFORMATION
Possible fix:

• Edited ext.all-dev.js

From
var view = this.views[0]
To
if (this.views[0]) {
var view = this.views[0]
}
else {
var view = this.view
}

• Reason: if the 2^nd tab not activated, it will not get the headerCt of it. But it still in somewhere which is in this.view
