lets antlr raise the following warning "Decision can match input such as "'correlatedAlarm' RULE_ID" using multiple alternatives: 1, 2".

Interestingly, this warning only shows up for contentassist-parser, but not for the runtime-parser.

This is a regression since it has been working flawlessly with Xtext 1.0.2

Workaround: enable backtracking for XtextAntlrUiGeneratorFragment.

I thought I already saw a bug report for this issue, but I can't find it anymore.
