[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-2192) AbstractMap from org.jboss.seam.international.Messages needs containsKey()

AbstractMap from org.jboss.seam.international.Messages needs containsKey() -------------------------------------------------------------------------- Key: JBSEAM-2192 URL: http://jira.jboss.com/jira/browse/JBSEAM-2192 Project: JBoss Seam Issue Type: Bug Components: Core Affects Versions: 2.0.0.CR2 Environment: Mac OSX, Jboss 4.2.1 Reporter: Damian Harvey Assigned To: Pete Muir Fix For: 2.0.1.GA Performing a containsKey() on the AbstractMap from org.jboss.seam.international.Messages results in severe performance problems (800ms on 1,800 properties compared to under 1ms for a get()) eg: @In Map<String, String> messages; //This is the Seam messages bundle public void aMethod() { if(messages.containsKey("key.mykey")) { //do something } } I traced the containsKey for a while but it went on a mad run through ELResolvers and Pages.java etc. Simple solution is to add a containsKey to the AbstractMap: public boolean containsKey(String key) { if(messages.get(key).equals(key)) { return false; } else { return true; } } Would be nice to know why this 'mad run' happened though. Hopefully not symptomatic of something wrong deeper down. Cheers, Damian.
