Hi Chad,
I have added the following lines of code to add actor programitically,
------------------------------------------------------------------------------------
LibraryIndex index = LibraryIndex.getInstance();
KeplerLSID lsid = new
KeplerLSID("urn:lsid:kepler-project.org:actor:701:1");
LibraryIndexComponentItem itemToAdd = new
LibraryIndexComponentItem(_actorNameStr, lsid);
System.out.println("itemtoAdd="+itemToAdd);
LibraryIndexItem subtree = index.findItem(new
KeplerLSID("urn:lsid:localhost:onto:1:1#PreConfiguredGridletActor"));
System.out.println("subtreeitem="+subtree);
index.add(itemToAdd, subtree);
LibraryIndex.getInstance().refresh();
-------------------------------------------------------------------------------------
I am getting the following error messages, by somehow it is not able to
resolve lsid.
Could you mind to look into it?
============================================================
[java] itemtoAdd=<component name="localActorName"
lsid="urn:lsid:kepler-pro
ject.org:actor:701:1"/>
[java] subtreeitem=<concept name="gridlets"
lsid="urn:lsid:localhost:onto:1
:1#PreConfiguredGridletActor"/>
[java] Could not resolve lsid urn:lsid:kepler-project.org:actor:701:1
