When programmatically selecting a TabItem with ScrolledComposite, the following Javascript error is displayed in the client's browser:

Could not evaluate javascript response:

org.eclipse.swt.custom.ScrolledComposite: Element must be created previously!

var req = org.eclipse.swt.Request.getInstance();req.setRequestCounter( "12" );var wm = org.eclipse.swt.WidgetManager.getInstance();var w = wm.findWidgetById( "w90" );w.setChecked( true );var w = wm.findWidgetById( "w92" );w.setChecked( false );var w = wm.findWidgetById( "w91" );w.setVisibility( true );var w = wm.findWidgetById( "w93" );w.setVisibility( false ); 

To demonstrate the problem, I've extended the mail demo so that upon double-clicking on a mail folder for a given account, an account view with tabs representing the various folders is displayed. The tab corresponding to the folder that was double-clicked in the navigation view is programmatically selected. The "Inbox" tab uses a ScrolledComposite whereas the other tabs do not.

Instructions in the "steps to reproduce" provide further explanation.





Reproducible: Always

Steps to Reproduce:
1. Within Navigator view, double-click on a non-Index folder to open an account view. Account view will open with tab corresponding to folder selected.
2. Double-click the Index folder within the Navigator view for that same account
3. Javascript error occurs

The error will not show if you select the Index tab within the new account view or if you double-click the Index tab when bringing up a new account view for the first time. The other tabs built with a simple Composite do not demonstrate this problem.
