Hi, I might be misunderstanding the question, but I don't see the bug in Ptolemy II 5.0-beta.
I put your code in to ptolemy/actor/lib/JTypedCompositeActor.java I had to modify the top part: --start-- package ptolemy.actor; import ptolemy.kernel.util.*; import ptolemy.kernel.*; import ptolemy.data.expr.*; public class JTypedCompositeActor extends TypedCompositeActor{ --end-- I then modified $PTII/ptolemy/configs/basicActorLibrary.xml and added <entity name="JComposite Actor" class="ptolemy.actor.JTypedCompositeActor"> </entity> When I compile the JTypedCompositeActor class and start up vergil, the JComposite Actor icon is present in vergil. File -> New -> Graph Drag the JComposite Actor into the graph editor Add a Const and a Display Connect the Const and Display Right click on the background of the graph editor, I can change the relation parameter. The resulting model is below: <?xml version="1.0" standalone="no"?> <!DOCTYPE entity PUBLIC "-//UC Berkeley//DTD MoML 1//EN" "http://ptolemy.eecs.berkeley.edu/xml/dtd/MoML_1.dtd"> <entity name="relation2" class="ptolemy.actor.TypedCompositeActor"> <property name="_createdBy" class="ptolemy.kernel.attributes.VersionAttribute" value="5.0-beta"> </property> <property name="_windowProperties" class="ptolemy.actor.gui.WindowPropertiesAttribute" value="{bounds={104, 125, 815, 518}, maximized=false}"> </property> <property name="_vergilSize" class="ptolemy.actor.gui.SizeAttribute" value="[600, 400]"> </property> <property name="_vergilZoomFactor" class="ptolemy.data.expr.ExpertParameter" value="1.0"> </property> <property name="_vergilCenter" class="ptolemy.data.expr.ExpertParameter" value="{300.0, 200.0}"> </property> <entity name="JComposite Actor" class="ptolemy.actor.JTypedCompositeActor"> <property name="_location" class="ptolemy.kernel.util.Location" value="{160.0, 125.0}"> </property> <property name="relation" class="ptolemy.data.expr.StringParameter" value="foo"> </property> <property name="_windowProperties" class="ptolemy.actor.gui.WindowPropertiesAttribute" value="{bounds={104, 125, 815, 518}, maximized=false}"> </property> <property name="_vergilSize" class="ptolemy.actor.gui.SizeAttribute" value="[600, 400]"> </property> <property name="_vergilZoomFactor" class="ptolemy.data.expr.ExpertParameter" value="1.0"> </property> <property name="_vergilCenter" class="ptolemy.data.expr.ExpertParameter" value="{300.0, 200.0}"> </property> <entity name="Const" class="ptolemy.actor.lib.Const"> <doc>Create a constant sequence.</doc> <property name="_icon" class="ptolemy.vergil.icon.BoxedValueIcon"> <property name="attributeName" class="ptolemy.kernel.util.StringAttribute" value="value"> </property> <property name="displayWidth" class="ptolemy.data.expr.Parameter" value="60"> </property> </property> <property name="_location" class="ptolemy.kernel.util.Location" value="{240, 135}"> </property> </entity> <entity name="Display" class="ptolemy.actor.lib.gui.Display"> <property name="_windowProperties" class="ptolemy.actor.gui.WindowPropertiesAttribute"> </property> <property name="_location" class="ptolemy.kernel.util.Location" value="{320, 180}"> </property> </entity> <relation name="relation" class="ptolemy.actor.TypedIORelation"> </relation> <link port="Const.output" relation="relation"/> <link port="Display.input" relation="relation"/> </entity> </entity> What behavior are you expecting to see? _Christopher -------- Hello Edward, I have made the following changes for creating property to the relation and I worked before, and it not working now, Could you mind to advise please?. 1. I did subclass the TpedCompisiteActor and I have overridden newRelation method which is as floows, ========================================================================== package griddles; ////////////////////////////////////////////////////////////////////////// //// JTypedCompositeActor public class JTypedCompositeActor extends TypedCompositeActor{ public JTypedCompositeActor() { super(); } public JTypedCompositeActor(Workspace workspace) { super(workspace); } public JTypedCompositeActor(CompositeEntity container, String name) throws IllegalActionException, NameDuplicationException { super(container, name); } public ComponentRelation newRelation(String name) throws NameDuplicationException { try { workspace().getWriteAccess(); TypedIORelation relation = new TypedIORelation(this, name); StringParameter param = new StringParameter(this, name); param.setExpression("Enter "+name); return relation; } catch (IllegalActionException ex) { // This exception should not occur, so we throw a runtime // exception. throw new InternalErrorException(this, ex, null); } finally { workspace().doneWriting(); } } } =========================================================================== === 2. I made the following changes to the configuration file, basicKeplerActorLibrary.xml <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> 3. I checked the new configuration file that was loaded while running kepler has loaded the updated configuration file, [java] *sys-package-mgr*: processing modified jar, 'C:\kepler\build\kepler-configs.jar'. 4. When I connect two actors with a relation, I am not able see any new property that was created in the JTypedCompositeActor. 5. Whereas when I do same thing few months back I was able to see property when ever I create new relation. with regards, Jagan Kommineni Edward A.
