Error in BaseIntFieldClassReader for ArrayList ( size == 1) ----------------------------------------------------------- Key: JBRULES-1766 URL: https://jira.jboss.org/jira/browse/JBRULES-1766 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 5.0.0.M2 Environment: Eclipse 3.4; Drools SVN trunk from today, Linux Reporter: Michael Zimmermann Assignee: Mark Proctor The following rule worked perfectly with drools 4.0.x. Using Drools Trunk (post 5.0 M1) I do get an error in org.drools.base.extractors.BaseIntClassFiieldReader. Changing the ArrayList (size==1) definition to ArrayList() works, though. rule "MyRule" when ArrayList( size == 1 ) from collect ( SomeClass( ) ) then do_something () end As this is some hack also published on the mailing list for counting facts, I would expect to see this contruct to be compatible with drools 4.0.x -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
