    Default Unanswered: Ext.selection.CheckboxModel - header is null

    Unanswered: Ext.selection.CheckboxModel - header is null


    Hello!

    I get this message, creating an Checkbox Selection Model:
    "Header is null"

    Is there anyway to set an header?

    I tried:

    new Ext.selection.CheckboxModel({text:'randomText'});

    new Ext.selection.CheckboxModel({header: 'randomText'});

    But nothing worked.

    Any Ideas?

    Edit:

    I dont geht the failure message when i am using:

    new Ext.selection.CheckboxModel({injectCheckbox: false});

    But i need the checkboxes

    To set a header I think you'd need to override this method:

    http://docs.sencha.com/ext-js/4-0/so...etHeaderConfig

    However, this doesn't really address the problem of that error message. Could you post a complete test case and your exact ExtJS version? The full stacktrace with line numbers would also be very useful (make sure you're using a debug version of ExtJS for meaningful line numbers).

    I had a look through the bugs forum but the closest I could find was this:

    http://www.sencha.com/forum/showthread.php?141633

    Similar but not quite the same. The fact that I couldn't find a known bug for this suggests that this probably isn't a bug in the CheckboxModel and that you've done something subtly wrong.
