Hi, I wonder if anyone could help me?
I'm attempting to use the 'from' keyword in the same fashion as the
sample found on the Release Notes/Language Improvement wiki. The
example shows a piece of syntax that uses the 'from' keyword to obtain
data via a Hibernate query. i.e:
$r : Restaurant( $postCode ) from hbSession.getNamedQuery( "some
query" ).setProperties( [ key1 : value2, key2 : value ] ).list()
I'm having difficulty executing syntax using this keyword because
Hibernate uses CGlib which relies on ASM 1.5.3 - the 'from' keyword
seems to rely on MVEL which uses ASM 3.0.
ASM 3.0 is not backwards compatible with ASM 1.5.3 and I get 'no such
method' errors.
So how does one get the 'from' keyword to work in an environment running
Hibernate?
Thanks,
Brad

For M2 I'll look at changing the namespace for ASM to avoid this issue.
Not sure how you'll avoid the issue till then.

should already be done - mvel may be using the wrong one.
Can you tell me what class it is that gives the nosuchmethod? (ie what the
target class is) and we can make sure all references are to inlined one so
this won't happen again.

This is more of an MVEL question, I guess, but do you know if there is a
way to force the use of reflection over ASM?

This is now corrected in MVEL 1.2beta16 which also inlines ASM with a
different package name. The MVEL author notes that while the jar
conflict stops the ASM optimiser, it'll still work as normal in the
fallback reflection mode.

actually I got that wrong. We already do change the namespace. The
problem is MVEL. MVEL uses reflection mode normally, but will use ASM if
its provided, so its MVEL that is having the problem.
