I also have validation errors both the MyEclipseIDE Version 5.5.1 GA and the latest MyEclipseIDE Full Stack Installer. Eclipse error markers appear to the left of every xmlns declaration (see code below).
I can make them disappear if I click MyEclipse > Preferences > MyEclipse > Validation and click “Allow projects to override these preference settings” and uncheck all the Build Validator checkboxes.
The odd thing is that I don’t get the errors in my local copy of JBoss-Seam-2.0.0.BETA1 examples–especially the bookings example. I can copy the code below into one of an .xml file in that project and I don’t get the validation errors.
Is my problem project specific and how can I fix it correctly?
