Bug 363046

Description jukefox 2011-11-07 09:06:03 EST

Build Identifier: M20110909-1335

After installation of the plugin

ATL SDK - ATLAS Transformation Language SDK	3.2.1.v20110914-0724	org.eclipse.m2m.atl.sdk.feature.group	Eclipse Modeling Project

and having a look at the Plugin-Properties there is an ATL-entry (I think it makes no sense that it is listed there and maybe this is already the bug). After navigating to "ATL" -> "Editor" -> "Typing" you will get a ClassCastException.

See the error details of the log below:
