One last thing : Even if everything works, I still get a stacktrace when I submit the form to save my object.
I think that the params interceptor tries to set the properties of the object "jspProfile" I have in my form (with <s:checkbox name="jspProfile.recpCheckErrorCount"/> for example), before the prepare interceptor initialize that object. Even if I initialize the object in the action's constructor, I get the stack. 2010-05-10 12:34:12,062 [http-8080-Processor24] WARN com.opensymphony.xwork2.ognl.OgnlValueStack - Error setting value ognl.OgnlException: target is null for setProperty(null, "recpCheckErrorCount", [Ljava.lang.String;@62812d) 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:192) at com.opensymphony.xwork2.ognl.OgnlValueStack.setValue(OgnlValueStack.java:155) at com.opensymphony.xwork2.ognl.OgnlValueStack.setValue(OgnlValueStack.java:143) at com.opensymphony.xwork2.interceptor.ParametersInterceptor.setParameters(ParametersInterceptor.java:273) at com.opensymphony.xwork2.interceptor.ParametersInterceptor.doIntercept(ParametersInterceptor.java:187) at com.opensymphony.xwork2.interceptor.MethodFilterInterceptor.intercept(MethodFilterInterceptor.java:87) ... 2010/5/10 Thomas Lulé <tho...@lule.fr>: > It works. > > Thanks a lot Lukasz and Alex. > > 2010/5/10 Alex Rodriguez Lopez <alo...@flordeutopia.pt>: >> Hi Thomas, >> >> use the paramsPrepareParams interceptor stack (or change yours), from >> struts-default.xml: >> >> <!-- An example of the paramsPrepareParams trick.
