Hi all !
I have some problem with a rule processing classes on a different package
thant the context.
I have an OCL method taking a parameter of a type defined in another emf
package (dreams.model). This parameter was unkonw at the compilation, so I
prefixed this parameter type by model:: and the compilation was ok.
But during the execution, when accessing to this parameter, I have an
OCLInvalid error (with ocl verbose). If the parameter type is in the same
package, I have no problem.
Any idea ?
Here is my OCL :
------------------------------------------------------------ ------------------
package dreams
context ResourceExtendedTest
def rankResource : rankResource(req : model::RequiredResource):Real=(
if (req.duration > 0) then
100.0
else
-0.0
endif
)
endpackage
------------------------------------------------------------ ------------------
Thanks in advance,
Samuel

Hi, Samuel,
The OclInvalid usually indicates some kind of RuntimeException in the
evaluation, like a ClassCastException, IllegalArgumentException, or
NullPointerException. Can you debug to find out which exception is
being thrown, where?
I don't have any ideas off-hand ... If you can provide a small
reproducible test case, you could attach it to a bug so we can
investigate the problem, in case it's a bug in the OCL interpreter.
Cheers,
Christian

Great! I'm glad you were able to resolve the problem.
Perhaps a little more diagnostic information from the interpreter would
have been useful to you.
