http://nagoya.apache.org/bugzilla/show_bug.cgi?id=8244 CallMethodRule rule can't be used to call no arg methods Summary: CallMethodRule rule can't be used to call no arg methods Product: Commons Version: unspecified Platform: All OS/Version: All Status: NEW Severity: Enhancement Priority: Other Component: Digester AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The digester's CallMethodRule rule can't be used to call methods taking no argument. The main issue is the semantic of the constructor, a paramCount of 0 doesn't stand for "no argument" but for "pass the tag body as argument", thus preventing the call of no arg methods on the parent objet. One could expect CallMethodRule to behave like Class.getMethod(), that is, a null or empty Class[] array means we are looking for a no argument method. Currently the decision is not made on the value of paramTypes but on the value of paramCount. If paramType is empty or null it's forced to an array with a single String.class element : in the constructor : if (paramTypes == null) { this.paramTypes = new Class[paramCount]; and later in end() : if (paramTypes.length == 0) { paramTypes = new Class[1]; paramTypes[0] = "abc".getClass(); } Fixing this issue is just a matter of letting paramTypes untouched till the method.invoke() call. -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
