The following mapping is throwing an NPE when I perform a search for the nested entry. The query is: InitialDirContext ctx = connect(); ctx.search("ou=XPT,ou=systems,o=teste", "ou=xhts", new SearchControls()) The db schema is pretty simple: function(function_id, function_name, system_id) system(system_id, system_desc) The penrose mapping is: <entry dn="ou=...,ou=systems,o=test"> <oc>organizationalUnit</oc> <oc>top</oc> <at name="ou" rdn="true"> <variable>system.system_id</variable> </at> <at name="description"> <variable>system.system_desc</variable> </at> <source name="system"> <source-name>system</source-name> <field name="system_id"> <variable>ou</variable> </field> <field name="system_desc"> <variable>description</variable> </field> </source> </entry> <entry dn="ou=...,ou=...,ou=systems,o=test"> <oc>organizationalUnit</oc> <oc>top</oc> <at name="ou" rdn="true"> <variable>function.function_name</variable> </at> <at name="description"> <variable>function.function_desc</variable> </at> <source name="function"> <source-name>function</source-name> <field name="function_name"> <variable>ou</variable> </field> <field name="system_id"> <variable>parent.ou</variable> </field> <field name="function_name"> <variable>description</variable> </field> </source> <relationship> <expression>system.system_id = function.system_id</expression> </relationship> </entry> And, finally, the exception is: java.lang.NullPointerException at org.safehaus.penrose.engine.LoadEngine.loadEntries(LoadEngine.java:308) at org.safehaus.penrose.engine.LoadEngine.loadBackground(LoadEngine.java:226) at org.safehaus.penrose.engine.LoadEngine.load(LoadEngine.java:106) at org.safehaus.penrose.engine.Engine.load(Engine.java:434) at org.safehaus.penrose.engine.DefaultEngine.expand(DefaultEngine.java:619) at org.safehaus.penrose.handler.SearchHandler.searchChildren(SearchHandler.java:297) at org.safehaus.penrose.handler.SearchHandler.search(SearchHandler.java:143) at org.safehaus.penrose.handler.Handler.searchInBackground(Handler.java:697) at org.safehaus.penrose.handler.Handler$1.run(Handler.java:567) at org.safehaus.penrose.thread.ThreadWorker.runIt(ThreadWorker.java:94) at org.safehaus.penrose.thread.ThreadWorker.runJobs(ThreadWorker.java:85) at org.safehaus.penrose.thread.ThreadWorker.access$0(ThreadWorker.java:72) at org.safehaus.penrose.thread.ThreadWorker$1.run(ThreadWorker.java:48) at java.lang.Thread.run(Thread.java:595) By adding "if(attributeMappings != null)" before line 308 in LoadEngine.loadEntries the problem goes away and the expected result is returned, but I'm pretty clueless if this is the proper way to fix it. Additional Comments From endisd dated Thu May 17 15:49:10 CDT 2007 In Penrose 1.2 the nested mapping has been rewritten and the following notation is no longer supported and should be removed: <relationship> <expression>system.system_id = function.system_id</expression> </relationship> Instead, the source relations should be specified inside the fields as follows: <source name="function"> <source-name>function</source-name> <field name="function_name"> <variable>ou</variable> </field> <field name="system_id"> <variable>system.system_id</variable> </field> <field name="function_name"> <variable>description</variable> </field> </source> ========================================================= Issue dump from jira $VAR1 = { 'priority' => '3', 'customFieldValues' => [], 'project' => 'PENROSE', 'status' => '5', 'components' => [ { 'name' => 'Engine', 'id' => '10009' } ], 'reporter' => 'kumpera', 'key' => 'PENROSE-202', 'assignee' => 'jimyang', 'summary' => 'Nested mapping throws NPE', 'id' => '10605', 'updated' => '2007-05-17 15:49:10.0', 'votes' => '0', 'fixVersions' => [ { 'releaseDate' => '2007-05-18 00:00:00.0', 'sequence' => '22', 'name' => 'Penrose-1.2', 'released' => 'true', 'id' => '10088', 'archived' => 'false' } ], 'description' => 'The following mapping is throwing an NPE when I perform a search for the nested entry.
