> ActionMappingParametersInteceptor is accessing request parameters

> Key: WW-2691
> URL: https://issues.apache.org/struts/browse/WW-2691
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.1.2
> Reporter: Musachy Barroso
> Assignee: Don Brown
> Priority: Critical
> Fix For: 2.1.3

> I am not really sure how this works, but it looks wrong to me. It seems like
> ActionMappingParametersInteceptor is trying to set parameters from the
> request, instead of the action mapping. To see it (throwing an exception) go
> to Tags/UI Example in showcase and click submit:
> ognl.OgnlException: target is null for setProperty(null, "birthday",
> [Ljava.lang.String;@a1fd57)
> at ognl.OgnlRuntime.setProperty(OgnlRuntime.java:1651)
> at ognl.ASTProperty.setValueBody(ASTProperty.java:101)
> at ognl.SimpleNode.evaluateSetValueBody(SimpleNode.java:177)
> at ognl.SimpleNode.setValue(SimpleNode.java:246)
> at ognl.ASTChain.setValueBody(ASTChain.java:172)
> at ognl.SimpleNode.evaluateSetValueBody(SimpleNode.java:177)
> at ognl.SimpleNode.setValue(SimpleNode.java:246)
> at ognl.Ognl.setValue(Ognl.java:476)
> at com.opensymphony.xwork2.ognl.OgnlUtil.setValue(OgnlUtil.java:197)
> at
> com.opensymphony.xwork2.ognl.OgnlValueStack.setValue(OgnlValueStack.java:150)
> at
> com.opensymphony.xwork2.ognl.OgnlValueStack.setValue(OgnlValueStack.java:138)
> at
> com.opensymphony.xwork2.interceptor.ParametersInterceptor.setParameters(ParametersInterceptor.java:205)
> at
> com.opensymphony.xwork2.interceptor.ParametersInterceptor.doIntercept(ParametersInterceptor.java:162)
> At first I thought it was the params interceptor, but it is
> ActionMappingParametersInteceptor. In this case it is trying to set
> "dojo.birthday" which will fail. If ActionMappingParametersInteceptor is
> supposed to handle request parameters somehow, then we need to ignore the
> "dojo.*" and "struts.*" parameters, but I don't think this was happening in
> 2.0.X (hence the ticket)
