There has always been an ambiguity in AS3 about [Foo] being interpretable as either metadata or as property access. (This is one reason we're changing the metadata syntax in AS4!) I don't remember the rule in the old compiler, but I think Falcon's rule is that if the [Foo] is the first nonwhitespace on a line then it is metadata, and this seems reasonable to me so I don't particularly want to change it.

If this stuff is allowed, then this is a bug in the grammar of antlr or the BaseASParser. I could see this as being a not so hard fix since to get into the array access or member state there has to be a correct predicate which would be foo. or foo[a] If Gordon doesn't chime in, I will look at the implementation. This is where it sucks we don't have unit tests for the ASParser! > Falcon doesn't allow multiline member access > -------------------------------------------- > > Key: FLEX-33320 > URL: https://issues.apache.org/jira/browse/FLEX-33320 > Project: Apache Flex > Issue Type: Bug > Reporter: Chema Balsas > Labels: Falcon > Attachments: MultilineArrayAccess.as, MultilineObjectAccess.as > > > Falcon doesn't allow multiline member access. > Try to compile any of the attached examples.
