Library method recognized as Apache Isis prefix

[Erik de Hair <e....@pocos.nl>]

Hi,

As of today I can't start our application any more:

"org.apache.commons.collections.ExtendedProperties#clearProperty: has 
prefix clear, is probably a supporting method for a property, collection 
or action."

It looks like the library wasn't changed in the mean time so why is this 
getting triggered suddenly?

Thanks,
Erik

I created an action returning a VelocityContext. That pulled the other 
dependency into the meta model. Just made the action programmatic and 
now it works. Thanks!

There must be some method that's returning an instance of this type, and so
is being interpreted as part of the metamodel.

As the error says, methods cannot start with "clear" as a prefix. But the
real problem is that type is leaking into your metamodel.

I suggest you put a breakpoint in ObjectReflectorDefault, eg
loadSpecification() to see when that happens and look back down the
stacktrace.

HTH,
Dan
