[CompleteOCL]definition uses definition [message #632189]

hi, all:
I am new to OCL.. I tried to reuse definitions in OCL. For example, in CompleteOCL editor:

def: criteria1(c:Integer):Boolean = c > 90 and c < 100
def: criteria2(c:Integer):Boolean = c > 80 and c < 95
def: check(r:Integer):Boolean = criteria1(r) and criteria2(r)

The editor could not resolve criteria1 and criteria2 in check. Does the OCL specification allow such reuse of defintions? Is this only a bug specific to the editor? Thanks!

Hi Liu

Yes, this is a known bug in the editor.

The underlying Java support should work, and indeed if you save the file
and put it through the

[The OCL specification indeed specifies that such reuse of definitions
is allowed, but unfortunately neglects to provide a mechanism for an AST
with such reuse to be persisted. A solution to the specification is
currently being prototyped within MDT/OCL and this will solve the editor
problem too.]

Hi,

Im also interested in the workaround for this bug, but apparently the answer got cut ("put it through the...").

Thanks,

Hi Juan

Sorry. The complete answer was "put it through the LPG (rather than
Xtext) parser".

This is fixed in the new release. M6 available in about 2 weeks. The new
release also removes forward/backward resolution problems.
