Struts 2 : redirect to action method on type conversion fail ?
Hi,
I've got a form with s:textfield mapped with Long variables in my
action class.
Also, my jsp displays some pre-computed information (that I retrieve
from database in my action's method).
When the user types letters in the number field, the type conversion
fails, and the JSP is reloaded. But the pre-computed infos are no more
displayed (because we did not execute the action's method).
I didn't find a way to redirect to the action's method even if type
conversion fails.
So I tried to store the pre-computed infos in http parameters by
adding a hidden field :
s:hidden name=archiveProfile.name /
s:property value=archiveProfile.name/
it did not work because of the archiveProfile thing.
I currently use a workaround, a s:hidden name=display/ field that
forces struts 2 to execute the setter :
public void setDisplay(String display){
display();
}
(display() is my method which loads stuff from db.)
That works but i'm afraid of potential side-effects, do you have a better idea ?
Thanks,
Thomas

That interceptor looks great, but is there any way to access request parameters in the prepare() method ? The http request provides an archiveProfileId parameter and I use that parameter to load my object archiveProfile. 2010/5/10 Lukasz Lenart lukasz.len...@googlemail.com: Use Preparable interface instead http://struts.apache.org/2.x/struts2-core/apidocs/com/opensymphony/xwork2/Preparable.html Regards -- Łukasz http://www.lenart.org.pl/ Kapituła Javarsovia 2010 http://javarsovia.pl - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org

Re: Struts 2 : redirect to action method on type conversion fail ?
Hi Thomas, use the paramsPrepareParams interceptor stack (or change yours), from struts-default.xml: !-- An example of the paramsPrepareParams trick. This stack is exactly the same as the defaultStack, except that it includes one extra interceptor before the prepare interceptor: the params interceptor. This is useful for when you wish to apply parameters directly to an object that you wish to load externally (such as a DAO or database or service layer), but can't load that object until at least the ID parameter has been loaded. By loading the parameters twice, you can retrieve the object in the prepare() method, allowing the second params interceptor to apply the values on the object. -- interceptor-stack name=paramsPrepareParamsStack ... I think this accomplishes what you are looking for (of course you need setters for the parameters that you want params interceptor to have ready for you by the time the prepare() method is called).

Re: Struts 2 : redirect to action method on type conversion fail ?
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.

I would like to know that aswell, so far I have been using javascript with jquery that is the lib that I use // somewhere inside the initial function $(input:text:visible:first).focus(); // or $(#othercontol).focus(); // if the first control is not a textbox.
