Jianwu, Many thanks! This works like a charm. I was having trouble navigating the structure of the ArrayType constructor, but I see how it works now. Brilliant!

Parris Cc: 'Kepler Users' Subject: Re: [kepler-users] Enforcing array subtypes. Hi Tom, Now it is much clearer. Thanks. I think you can add 'portparameter.setTypeEquals(new ArrayType(BaseType.INT));' before 'portparameter.setExpression("{1}");' to constrain its type. It will make sure the portparameter will only have a vector of integer. I just tried this way. If users specify wrong values, a dialogue will show up explaining the error. It's not on my head how to constrain the port or portparameter to have between 1 and 5 value. Maybe you need define a separate Type that could only have value between 1 and 5, and replace the above BaseType.INT to this type?
