preTarget variable not available in Connection Complete Precondition [message #1403570]

1. In Connection Complete Precondition of Edge creation tool, preTarget is not available to use in the expression. while preSource variable is available in Connection Start Precondition.
What may be the problem?

2. One more issue:
How to compare the enum variables?
for example
[source.oclAsType(Port).type = port_type::in/]
does not work

Any help much appreciated

1. This is a known bug in Sirius, the "preSource" and "preTarget"
variables are not accessible in completion or validation but there are
correctly computed when evaluated in runtime. So you should ignore the
validation issue on your VSM, your expression will work

2. This is the expected OCL Syntax, it should work.
If you still have issue, you may write this expression with java and
reference it through the service interpreter (service:), see [1] and [2]
for further details about this service interpreter

Alex
