Iterate over an ArrayList of arrays
Hi,
I've got an ArrayList named "breadcrumbs" in my action that
I would like to display in my JSP.
Something like :
${value[0]}
I want to iterate over the ArrayList, then get the two values of the
array, but this code obviously doesn't work.
Do you have any better idea ?
Thank you,
Thomas

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 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 : > It works. > > Thanks a lot Lukasz and Alex. > > 2010/5/10 Alex Rodriguez Lopez : >> Hi Thomas, >> >> use the paramsPrepareParams interceptor stack (or change yours), from >> struts-default.xml: >> >> >> >> ... >> >> 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). >> >> Em 10-05-2010 09:39, Thomas Lulé escreveu: >>> >>> 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: >>>> >>>> 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 >>> >> >> >> - >> 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 ?
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 : > 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
Struts 2 : redirect to action method on type conversion fail ?
Hi,
I've got a form with 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 :
it did not work because of the "archiveProfile" thing.
I currently use a workaround, a 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
