Re: Widget Updating Content Of Another Panel

No, it's added to the main layout and then exposed through a getter(), which is passed into activityManager.setDisplay(template.getAppPanel());  Those are the only references to it.

Do you use 'appPanel' in different places? an element can have only one parent, adding an element to a different parent automatically removes it from its previous parent.

My bug was due to having introduced a second instance of my template, so when calling to update content it as on the second instance, not the one actually being displayed.

I tried switching from DockLayoutPanel to HeaderPanel as suggested by Vassilis, but I can't get the content area to be scrollable.  Here's the two versions of code, and screenshots that show the issue. Does anyone know what the problem is?

Here's the two versions of my code.  First up, this uses DockLayoutPanel, and renders correctly.

And here's the version with HeaderPanel, the center content is not scrollable.

Furthermore I would suggest the HeaderPanel (terrible name - but very cool widget) instead of the DockLayoutPanel so your header and footer can be __naturally__ sized without having to specify exact size.

Put a SimplePanel in your DockLayoutPanel and then set the ActionBar into that SimplePanel using SimplePanel.setWidget().

In your setActionBar() method call SimplePanel.setWidget(newBar) to replace the old ActionBar with the new one.

So you basically put a container widget into your DockLayoutPanel and then update the contents of the container widget through your setter method.
