Migrating to RC 2
If you've been using the eXpressApp Framework since our earlier
Beta 2 release, you might have projects that make use of certain
features, or rely on certain implementation details that have
changed for the Release Candidate 2 release. This document is a
list of such changes that we are aware of and that we anticipated
to be problematic. I hope we haven't forgotten anything severe,
please let us know if you find anything.
Note: the migration from the interim RC 1 version to the current RC 2 doesn't require any special steps.
Namespace DevExpress.Persistent.Validation.SingleObject removed
If you have any using or Imports statements
for the namespace DevExpress.Persistent.Validation.SingleObject, you must remove them.
ViewNavigationController is now a base class
We have introduced two new classes
WinViewNavigationController and
WebViewNavigationController, both of which are
derived from ViewNavigationController. If your own
application has controllers derived from
ViewNavigationController, you will now see four
buttons for view navigation instead of two. You should derive
your controller from either
WinViewNavigationController or
WebViewNavigationController now, instead of from
ViewNavigationController.
Image Resource support in Web applications
The Web.config for existing XAF Web applications must
be extended to include the following section inside the
<system.web> section:
<httpHandlers>
<add verb="*" path="ImageResource.axd" type="DevExpress.ExpressApp.Web.ImageResourceHttpHandler"/>
</httpHandlers>
Without this change, all images will be missing from your Web
application.
