Unable to resolve class from Groovy script

[Neil Gordon]

Hello,

Is it possible to reference custom model classes (PO's) that are located in my plugin, from a Groovy script?

I get an error 'Unable to resolve class' referring to my model classes when starting a Groovy script from my plugin.

References to classes which are in org.adempiere.base do not trigger an error.

I start the Groovy script from within my plugin as follows:

            //Adapted from: ProcessUtil.startScriptProcess

            ScriptEngine engine = rule.getScriptEngine();

            MRule.setContext(engine, getCtx(), 0); // no window

            // now add the method arguments to the engine
            engine.put("A_Ctx", getCtx());
            engine.put("A_TrxName", getTrxName());
            msg = engine.eval(rule.getScript()).toString();

Part of the stack trace is as follows:

Script1.groovy: 23: unable to resolve class org.compiere.model.MCustomTable

Any help would be appreciated.
