[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-1735) Pages.getStringValuesFromModel throws ConcurrentModificationException

Pages.getStringValuesFromModel throws ConcurrentModificationException --------------------------------------------------------------------- Key: JBSEAM-1735 URL: http://jira.jboss.com/jira/browse/JBSEAM-1735 Project: JBoss Seam Issue Type: Bug Components: Core Reporter: Darryl Smith Fix For: 2.0.2.GA I don't see how this is happening from looking at the code, but occasionally I get a ConcurrentModificationException from Pages.getStringValuesFromModel. I can not reproduce it on demand. Only place that access this collection is Pages:971 page.getParameters().add( parseParam(param) ); but this shouldn't be called after init from what I can see.
