Hi all,
Im trying to copy the associations between selected classes from the
source model to the target one. The metamodels for both the source and
target are UML2. I selected first the classes to be copied according to
their stereotypes then I need to select the associations according to the
stereotype of their member ends. Since I couldnt navigate the target
model to copy only the associations of its classes, I have to repeat the
same condition in the association rule.
I use these rules to copy the classes and their associations, but I get
this error could not find operation hasStereotype on Sequence(OclAny)
having supertypes: [Collection(OclAny)] . A helper called hasStereotype
is defined and works fine only with the rule CopyClass. I get the same
error if I use isStereotypeApplied()
rule CopyAssociation{
from
s : UML!Association (s.memberEnd.hasStereotype(' myStereotype'))
to
t : UML!Association (
name <- s.name,
ownedEnd <- s.ownedEnd,
memberEnd <- s.memberEnd
)
}
rule CopyClass{
from
s : UML!Class (s.hasStereotype('myStereotype'))
to
t : UML!Class (
name <- s.name,
ownedAttribute <- s.ownedAttribute,
ownedOperation <- s.ownedOperation,
generalization <- s.generalization
)
)
How can I access this helper through the association?
Do I need to use a lazy rule to call it when I need to copy a specific
association or just a condition in a matched rule is enough?
Is the order of these two rules matter? If the CopyClass rule executed
first, then the selected classes are moved from the source model to the
target model and the second CopyAssociation rule will not find these
classes in the source model. Or we dont modify the source model so the
order doesnt matter.
Any help would be appreciated!

Hi Rasha
When i worked with ATL on UML2 I had some problems too with stereotypes
some solutions to try
1) try UML2 handler
2) instead of using s.hasStereotype
make an helper which will execute this (sorry for helper syntax i don't
remember):
helper personnalHasStereotype(name :String) .... =
s.getAppliedStereotypes()->select(s | s.name = name)
and try to put a debug on s.getAppliedStereotypes
I really have this problem and it seems the stereotypes methods with
Strings doesn't work

Hi Rasha,
After getting that connected info message you have to switch to the
Debug perspective.
