[jboss-user] [JBoss Seam] - why Seam cant invoke destroy method?

Hello I have one Stateful and one conversational bean in my project. sometimes the Seam can not invoke the destroy() method and throws an exception. this exception can been seen on tomcat console with following message: it's wondering me why this happen sometimes not always! I have declared this method in the local interface and marked them with @Remove and @Destroy in its implementation class. also, I handled any exception might be happen in destroy method by putting try/catch statement. | java.lang.NullPointerException | at org.jboss.ejb3.stateful.StatefulLocalProxy.invoke(StatefulLocalProxy.java:98) | at $Proxy12.destroy(Unknown Source) | at
