GWT Error After IDEA 7 Upgrade


I have just upgraded to IntelliJ IDEA 7, and suddenly I'm seeing this message in the Dev Shell window:

Errors in 'jar:file:/C:/JBLibraries/gwt-windows-1.4.60/gwt-user.jar!/com/google/gwt/user/client/impl/'
Line 56: The method createObject() is undefined for the type JavaScriptObject

Clearly the immediate cause is the IDEA upgrade, but the message seems to belong to GWT. Needless to say, gwt-user.jar shows no sign that it has changed.

When the message first appeared the project used to run OK, but I made the mistake of running a full rebuild to try to get rid of it, and now IDEA knows about the error and won't run the project!

Can anybody help with this?

It seems this results from inappropriate GWT libraries, or possibly duplicated GWT libraries, being included in the module dependencies. After the transition from IDEA 6 to 7 the dependency list appeared somewhat munged, so I removed all the GWT libraries and just added back gwt-user.jar, and with a full rebuild everything is OK.
