Bendpoint problem again [message #180719]

Hello！Randy and other guys:

I am sorry to trouble you again. A few days ago, I asked a question
about the bendpoint when updating our project from eclipse 2.1.2 to
eclipse 3.0.2, which is: when I select a connection with no bendpoint,
no new bendpoint is created automatically, and the
java.lang.NullPointerException occurs at the function
createHandlesForUserBendpoints in the class “BendpointEditPolicy”.

And you have suggested me to add an empty list as constraint for my
connection. I have made a try, but I find that the function
“SetRoutingConstraint” and “GetRoutingConstraint”of Connection are
interface function, so when I set a empty list, nothing has been done.
But in the function “refreshBendpoint” in the “logic” example, those two
functions work. So I want to ask where should I set the empty list for
my connection.

Thanks a lot!

Are you not using any router?

Somebody else had complained about the same thing and in my workspace
BendpointEditPolicy checks to see if the routing constraint is null. Open a
bug report and I'll release the change.
