Hi all,

I’m on a POC to migrate from RAD 7.5 to MyEclipse Blue 8.6 for my company. The migration works correctly and when I finished it, I commit all my changement (new files and other) with SVN.
But when I do a checkout of my workspace and try to open it with MyEclipse Blue I have the following error. This error occurs for “Initializing Java Tooling”, “Update Installed JREs” and when I close the Workspace (during the step to save the state of workspace):

java.lang.ClassCastException: org.eclipse.wst.common.componentcore.internal.resources.VirtualComponent cannot be cast to org.eclipse.jst.j2ee.componentcore.util.EARVirtualComponent

Hi,

I found a workaround. I have to delete projects from my workspace and then i commit my .metadat folder.
So when i make a checkout, I open my workspace with MyEclipse Blue and then I import my projects into it.
With this workaround, projects load and build correctly but i want to be able to save my workspace without deleting my project from it.

Can you help me?

Thanks.
