[jboss-user] [JBoss Seam] - Re: NullPointer during Identity.hasPermission ?

Thank you, Shane. I was aware that it is a varargs param, but I did not know that it behaved differently for hasPermission(String, String) and hasPermission(String, String, null). In both cases it should throw a NullPointer in this line: for (int i = 0; i < arg.length; i++) Apart from that, as I said I have stumbled into this solution after several iterations. The code I have had previously looked like this (adapted from the documentation) public void deleteCustomer() { | Identity.instance().checkRestriction("#{s:hasPermission('customer','delete',null)}"); | } The null was added by me. Without the third parameter I get the following error javax.el.ELException: Function 's:hasPermission' specifies 3 params, but 2 were declared | at org.jboss.el.lang.ExpressionBuilder.visit(ExpressionBuilder.java:181) | at org.jboss.el.parser.SimpleNode.accept(SimpleNode.java:129) | at org.jboss.el.lang.ExpressionBuilder.prepare(ExpressionBuilder.java:138) | at org.jboss.el.lang.ExpressionBuilder.build(ExpressionBuilder.java:152) | at org.jboss.el.lang.ExpressionBuilder.createValueExpression(ExpressionBuilder.java:195) | at org.jboss.el.ExpressionFactoryImpl.createValueExpression(ExpressionFactoryImpl.java:68) | at org.jboss.seam.el.SeamExpressionFactory.createValueExpression(SeamExpressionFactory.java:98) No way to specify only 2 parameters, and 3 parameters result in a null pointer. I cannot believe this is intended. I have some questions now: * is there a general contract for the different behavior on the hasPermission method without a 3rd parameter and null as the third parameter? (the null pointer is thrown, when I use the syntax with s:checkPermission) | * Is the last exception ok this way? | * Shouldn't there be a method without the third parameter?
