error.txt

Similar replication procedures to bug #784656 but the stack trace is different and the cause is apparantly different.

See the attached error.txt for the stack trace. Notice it doesn't involve any portlets, which is why I'm creating this separate from bug 784656. #784656 involved specifically the platform utilization portlet but nothign in the stack trace for this issue involves that portlet.
Comment 1 John Mazzitelli 2012-04-24 13:48:00 EDT
from the stack trace, it looks like one of these calls to addChild is passing in null:

    public void setContent(Canvas newContent) {
        if (newContent instanceof HasViewName) {
            LocatableVLayout decoratedContent = decorateWithTitleBar(((HasViewName) newContent).getViewName(),
                newContent);
            contentCanvas.addChild(decoratedContent);
        } else {
            contentCanvas.addChild(newContent);
        }
