[kepler-dev] Dynamicalling adding properties (attributes) to the relation ......

[jagan]

Hello Ilkay,


In continuation to my previous mail,  even If I remove the Composite 
Actor entry in the configuration file basicKeplerActorLibrary.xml
still I am able to create a relation without any error message. It looks 
for me my JTypedCompositeActor hasn't been loaded.

Do you know is there any other location where the Composite Actor has 
been configured?

with regards,

Jagan Kommineni


--------------------------
This entry I removed from the basicKeplerActorLibrary.xml file ....
<entity name="Composite Actor" class="griddles.JTypedCompositeActor">
     <property name="entityId" 
class="org.ecoinformatics.seek.util.NamedObjId" 
value="urn:lsid:ecoinformatics.org:kepler.118.1"/>
   </entity>
------------------------------
