Can I get a test case? Tested against 2.1.0 b1, 2.0.2 and 2.0.1.1 with both these test cases and do not get an error:

new Ext.Toolbar().setTitle(undefined);

var cnt = new Ext.Container({
    fullscreen : true,
    items      : [
        {
            xtype  : 'toolbar',
            docked : 'top'
        }
    ]
});

var toolbar = cnt.down('toolbar');

toolbar.setTitle(undefined);

Thanks for the response.

Hmm I didn't try a unit test. It doesn't throw an error this way (not sure what I screwed up in my code); however, setting the title after passing undefined doesn't seem to work.

var cnt = new Ext.Container({    fullscreen : true,    items      : [        {            xtype  : 'toolbar',            docked : 'top'        }    ]});var toolbar = cnt.down('toolbar');toolbar.setTitle(undefined);toolbar.setTitle('some title');

Ugh that didn't format very well.

var cnt = new Ext.Container({
    fullscreen : true,
    items      : [
        {
            xtype  : 'toolbar',
            docked : 'top'
        }
    ]
});


var toolbar = cnt.down('toolbar');


toolbar.setTitle(undefined);
toolbar.setTitle( 'some title' );

This is working for me:

var cnt = new Ext.Container({
    fullscreen : true,
    items      : [
        {
            xtype  : 'toolbar',
            docked : 'top'
        }
    ]
});

var toolbar = cnt.down('toolbar');

toolbar.setTitle(undefined);

toolbar.setTitle('Test');

Not really sure. I put a workaround in for now anyway.

Here's the exact build I'm using:

This bug still exists in 2.1.0.
