http://issues.apache.org/bugzilla/show_bug.cgi?id=37600 Summary: Using Object as a tag property class automatically changes the value to a String Product: Commons Version: 1.0 Final Platform: Other OS/Version: other Status: NEW Severity: major Priority: P3 Component: Jelly AssignedTo: commons-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] Hi I recently found a bug in either the Jelly Engine, or in some of the tags which are provided. I encountered a problem with the following code: <c:new className="java.lang.Long" var="value"> <c:arg type="long" value="${12345}"/> </c:new> <c:new className="Profile" var="profile"/> <c:invoke method="setValue" on="${profile}"> <c:arg type="java.lang.Long" value="${321}"/> <c:arg type="java.lang.Long" value="${123}"/> <c:arg value="${value}"/> </c:invoke> the Profile setValue method takes three arguments; Long, Long, Object Invoking the code results in the arg always passing the value to the invoke tag as a String, not as an Object. I looked into the ArgTag source code seeing that it is using java.lang.Object as the type property class, not the ....jelly.Expression class. Since I was unsure I created my own tag and taglib to simulate the problem. public class MyTag extends TagSupport { private Object object = null; private Object expr = null; public void setObject(Object object) { this.object = object; } public void setExpression(Expression expr) { this.expr = expr.evaluate(this.getContext()); } public void doTag(XMLOutput output) throws MissingAttributeException, JellyTagException { System.out.println(object+" ("+object.getClass().getName()+")"); System.out.println(expr+" ("+expr.getClass().getName()+")"); } } executing the following script confirms the issue <c:new className="java.lang.Long" var="value"> <c:arg type="long" value="${12345}"/> </c:new> <my:tag object="${value}" expression="${value}"/> it result printing the following tho lines: 12345 (java.lang.String) 12345 (java.lang.Long) Is this a problem in the engine, or should the arg tag be using the Expression class instead of Object?
