ETL problem [message #589163]

Hello.

I'm trying do a transformation using ETL.

I have this model, created by a other previous transformation:

<?xml version="1.0" encoding="ASCII"?>
<xmi:XMI xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:pimnat="afpl.nat.pim">
<pimnat:Policy id="fw2">
<rule>
<filter interface="eth1" direction="out" action="deny">
<matches ipsrc="10.1.1.0/24" ipdst="10.10.10.2" protocol="*" prtsrc="*" prtdst="*"/>
</filter>
</rule>
<rule>
<filter interface="eth2" direction="in" action="deny">
<matches ipsrc="10.1.1.0/24" ipdst="10.1.1.3" protocol="tcp" prtsrc="*" prtdst="23"/>
</filter>
</rule>
</pimnat:Policy>
</xmi:XMI>

And two rules for try. This is the first one:
rule trasnform_policie
transform f: Source!Policy
to p : Target!Policy{

"policy".println();
}
and it's working ok.

And the second one:

rule trasnform_policie2
transform f: Source!Rule
to p : Target!Filter_Rule{

f.println();
"hello".println();
}

But when I executed this rule, nothing hapen

The problem is that ETL is not taking <rule> like Source!Rule, but I don't know why. I have checked the metamodel and I think every is ok.

Any idea?

Thank you very very much for your help!!!

Hi Jose Miguel,

Is perhaps Rule an abstract class? If so, you should add a @greedy
annotation to your second rule:

@greedy
rule trasnform_policie2
transform f: Source!Rule
to p : Target!Filter_Rule{

f.println();
"hello".println();
}

If this is not the case, could you please send me your metamodels, ETL
and a sample model so that I can have a look at this?

Cheers,
Dimitris

Hi Dimitris,

I've got the same problem with some of my rules. everything looks fine in my .ecore model.
I have tried the @greedy, but it doesn't work either.
Can you please help me ?
