does order matter in gwt descriptor?

If you use maven to perform operations on your project you may have used:

mvn vaadin:update-widgetset

It examines your classpath and updates your gwt descriptor file (e.g. MyWidgetSet.gwt.xml) with entries for the Add-ons it discovers.  However, not sure if it guarantees the proper order of those entries.

For example:

If you have played with the awesome QuickTickets demo you may recall a file called "DashboardWidgetSet.gwt.xml".  It comes with the proper entries in the proper order for the add-ons.  But if you strip them out and run the vaadin:update-widgetset goal you may get some errors at runtime.

Bad Quicktickets:

<inherits name="com.vaadin.addon.timeline.gwt.TimelineWidgetSet" />
<inherits name="com.vaadin.addon.charts.Widgetset" />

Message:

Widgetset 'com.vaadin.demo.dashboard.DashboardWidgetSet' does not contain
implementation for com.vaadin.addon.timeline.Timeline. Check its component
connector's @Connect mapping, widgetsets GWT module description file and
re-compile your widgetset. In case you have downloaded a vaadin add-on package,
you might want to refer to...

 The above "Message" was showing up in each panel on the 'Dashboard' of the QuickTickets demo.  After re-ordering [see below] - and recompiling the widgetset all was fixed.

The odd part is that I was unable to reproduce the behavior.

It is unclear why.

Good Quicktickets:

<inherits name="com.vaadin.addon.charts.Widgetset" />
<inherits name="com.vaadin.addon.timeline.gwt.TimelineWidgetSet" />
