Build Identifier: Xtext 2.0 Trunk as of 2011-03-18 Xbase does Support Closures with more than 6 Parameters but the Compiler/Validator does not. So provide a Validation rule that gives the user an error. Reproducible: Always Steps to Reproduce: Taking following Xtend2 example class Test { doit() { var n = [Integer i1,Integer i2,Integer i3,Integer i4,Integer i5,Integer i6, Integer i7|i1] } } this is valid in the editor but does not compile / give error on the console java.lang.RuntimeException: org.eclipse.emf.common.util.WrappedException: XbaseJavaValidator#checkTypes for

Hi Christian, thanks for the report - we are aware of the missing validation. Do you see an actual use case for more than 6 parameters? Regards, Sebastian
Hi, no i do not see an usecase for more than 6 parameters - thus a validation rule would be ok for me ;-)
