Ok, i'll test this and I'll come back to you. Thanks. On 08/01/2013 04:00 PM, Lukasz Lenart wrote: Can you test with the latest SNAPSHOT? This can be related to https://issues.apache.org/jira/browse/WW-4142 And you can directly use DefaultActionMapper from 2.3.15.1, just copy the code and define your custom Action mapper as specified in the docs. Regards -- Łukasz + 48 606 323 122 http://www.lenart.org.pl/ 2013/7/31 Thim Anneessens <t.anneess...@ictjob.be> Hi Struts users, I am having problems migrating from version 2.3.1.2 to version 2.3.15.1. This upgrade seems pretty important as it fixes a known security issue. The problem I am having is the that apparently, I can no longer check if a property has been given to my Struts component (using s:component and s:param)  by testing that the value associated to the parameter key in the "parameters" is equal to null. Test This is the code of the component that I call: <h1>Param items</h1> <s:property value="parameters.items.class.name"/> <h1>Radom param name</h1> <s:property value="parameters.radomParamnameDynamo.class.name"/><br/> <s:property value="parameters.radomParamnameDynamo"/><br/> <s:property value="parameters.radomParamnameDynamo"/><br/> <s:property value="parameters.radomParamnameDynamo2"/> <s:property value="test"/> Here is the call to the component: <s:component template="TestComponent.jsp"> </s:component> And here is the produced output (without html marking) Param items java.lang.Object #Output of <s:property value="parameters.items.class.name"/> Radom param name java.lang.Object #Output of <s:property value="parameters.radomParamnameDynamo.class.name"/> java.lang.Object@3c0e5477 #Output of <s:property value="parameters.radomParamnameDynamo"/> java.lang.Object@3c0e5477 #Output of <s:property value="parameters.radomParamnameDynamo"/> (the second one) java.lang.Object@e91824 #Output of <s:property value="parameters.radomParamnameDynamo2"/> test #Output of <s:property value="test"/> Note: test is a property of the action that should return the "test" string. OK. I Environment Java 6 struts-javatemplate-plugin (same version as struts) JRebel Tomcat (restarted and cleaned), Eclipse(restarted & project recompiled) Analysis Action properties are acting as before (I've checked with the debugger, and the non existence of an action property result in a null value) The Component "parameters" object will always return a value (even if it is an object) By using the debugger, we can see that accessing an unexisting "parameters" key will result in the creation of this "parameters" key and its association to an object of type Object. 2 unexisting "parameters" key will result in the association of 2 distinct objects of type Object. (as illustrated in the output of the Test) What I have tried I hope I provided enough information and that you will be able to tell me what I do wrong, how I could get out of this mess or that there is a bug ;).
