[rules-users] Decision table accessing my own methods

[djb]

Thanks,

Neither suggestion worked, unfortunately.

I have imported the object model. (eg. com.schoolstuff.*)

Excuse the syntax I used, but my method is not static, and it wouldn't make
sense to make it so.  (Or, I'd have to pass in ClassRoom and Student).

I tried with this.hasStudent("$param") and hasStudent("$param") with no
luck.  Since my method returns a boolean, will it know to evaluate the
column as a true or false condition?

Any other ideas?

-Daniel

PS (I'm not sure if my first reply was successfully posted, sorry if this is
a repeat.)
