Groovy project throwing ArrayIndexOutOfBounds Exception during deployment

[Venkatesh]

Hi,
Recently, we have mixed groovy classes into a java project that
outputs a web archive (.war). We have also converted the project into
a groovy project to get Groovy-Eclipse plugin to compile our groovy
classes. But since then, we are facing ArruIndexOutOfBoundsException
while deploying the .war in JBoss. It seems more coming from the
reflection part of it where it is trying to get the Extensions
working. It looks like, IPF fails to return the method arguments
correctly resulting in ArrayIndexOutOfBoundsException. IPF extensions,
I have been trying are FlowModelExtensions Any idea guys?

Hi,

are you sure that the exception is caused by IPF's FlowModelExtensions and not by some project-specific DSL extensions? How is the DefaultModelExtender bean defined in your Spring context?

Hi Dmytro,
IPF extensions are only the extensions we are loading from the
applicationContext. In fact, entire setup are from IPF examples. Btw,
here is the model extender bean defined in applicationContext.

<bean id="routeModelExtender"

class="org.openehealth.ipf.platform.camel.core.extend.DefaultModelExtender">
<property name="routeModelExtensions">
<list>
<ref bean="coreModelExtension" />
<ref bean="sampleModelExtension" />
<ref bean="flowModelExtension"/>
</list>
</property>
</bean>

Thanks & Regards

Mistake is from my side..did not make the route to depend on
'routeModelExtender' - your question about the Model Extender made to
look at the applicationContext again and it is working now..Btw, I
feel, the error (exception) is little off the context.
