Grails-melody plugin breaks the filterpane plugin about javamelody HOT 4 CLOSED

just to push it a little forward...
The problem seems to appear only with recent versions of Grails (and of Groovy).

Grails Melody plugin is here:
http://plugins.grails.org/grails-grails-melody/trunk/GrailsMelodyGrailsPlugin.gr
oovy
and the exception thrown is in the else of the plugin (line 158) because it 
seems
that the metaMethod is not found.

But this code seems ok when I read some examples on the Internet like the last 
one in
http://groovy.codehaus.org/ExpandoMetaClass+Domain-Specific+Language

All that I see from examples on Internet is that perhaps we can try to replace
"delegate.metaClass.getMetaMethod(name, args)" by
"delegate.class.metaClass.getMetaMethod(name, args)" (but I did not test that).

The FilterService.groovy is here:
http://plugins.grails.org/grails-filterpane/trunk/grails-app/services/com/zeddwa
re/grails/plugins/filterpane/FilterService.groovy
Is there a problem with "def params" in the "filter" method?
Or is there a problem with the fact that there is 2 "filter" methods in this 
file?

And for reference, MetaMethod, MetaClass and ExpandoMetaClass of Groovy 1.7.2 
are here:
http://www.jarvana.com/jarvana/view/org/codehaus/groovy/groovy/1.7.2/groovy-1.7.
2-sources.jar!/groovy/lang/MetaMethod.java?format=ok
http://www.jarvana.com/jarvana/view/org/codehaus/groovy/groovy/1.7.2/groovy-1.7.
2-sources.jar!/groovy/lang/MetaClassImpl.java?format=ok
http://www.jarvana.com/jarvana/view/org/codehaus/groovy/groovy/1.7.2/groovy-1.7.
2-sources.jar!/groovy/lang/ExpandoMetaClass.java?format=ok

Any idea?

I have just seen this post with a similar issue:
http://groups.google.com/group/nimbleproject/browse_thread/thread/3a2b38e968f3de
10/828cfa957569816d?q=javamelody#828cfa957569816d

And it was solved by replacing "def init = " with "public void init() " in the 
service:
http://github.com/bradleybeddoes/nimble/commit/1a965cac113fd0a56077a2c327b553e6e
b872dbd

How could we change "def filter(def params, Class filterClass) {" in
http://plugins.grails.org/grails-filterpane/trunk/grails-app/services/com/zeddwa
re/grails/plugins/filterpane/FilterService.groovy
?

Would it work?

It doesn't look like the exact same issue. Nimble had a problem with a closure
defined in a service; whereas there are no closures in FilterPane's 
FilterService.
Maybe the "private" methods are a problem? Could Steve move those methods to a 
Groovy
class or make them public?

Fixed by Liu Chao in JavaMelody Grails plugin v0.3 which is now released 
(including
JavaMelody v1.15.0).
