Subject RE: Preserving Messages and Garbage values Across a Redirect in Struts 2
Date Thu, 26 Nov 2009 13:13:15 GMT
Messages are stored since you use RedirectMessageInterceptor.

Action property Data is not retained during redirect.

Try following scenarios,

 

Method1:

So you need to set explicitly from Action property to ActionContext in
Action1 and Need to retrive from the context and set to properties in
Action2.

Method2:

Try to use alias interceptor and put alias through the <param> tag in
struts.xml  of Action1 and Action2 properties as below.

<param name="aliases">#{ 'action1Property1' : 'action2Property1',
'action2Property2' : 'action2Property2'}</param>

<interceptor-ref name="alias"/>

 

Method3:

Have you tried chain instead of redirectaction and use same properties in
Action1 and Action2.

Struts 2

 

 

I donno If i can able to explain it to you, I will try my  best , here is
the

secinario

 

 

Step 1.  When the user click the button on the page, depend on the string

return from the action method the page will be display and is configured in

the struts.xml file as mention below.

  

           <action name="determineCaseEvaluationType" 

class="com.activity.EvaluateCaseAction"

method="determineCaseEvaluationType">

            <result name="guidelInitConsid"

type="tiles">editGuidelinesCaseEvaluation</result>

            <result name="shrtsntcInitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

            <result name="sscat2p1InitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

        </action>

 

step 2. There are fields in the pages like 10 text boxes 2 drop down and 2

radio buttons , when I fill all the field and click submit it will do the

neccessary business operation and return the string to which page is to

display, and is mention in the struts.xml file as mention below

         

       <action name="saveInitConsiderationEval"

class="com.activity.EvaluateCaseAction"  method="saveInitConsiderationEval">

            <interceptor-ref name="redirectInput"/>

            <result name="success" type="redirect-action">

                  determineCaseEvaluationType

            </result>

            <result name="input" type="redirect-action">

            determineCaseEvaluationTypeForInput

      </result>

        </action>

 

step 3. : when valiations fails I need to determine on which page

validations failed and hence I am forwarding the the input to method which

it will determine what page to be displayed.

 

<action name="determineCaseEvaluationTypeForInput"

class="us.ga.state.pap.cons.clemency.presentation.action.activity.EvaluateCa
seAction"

method="determineCaseEvaluationTypeForInput">

            <result name="guidelInitConsid"

type="tiles">editGuidelinesCaseEvaluation</result>

            <result name="shrtsntcInitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

            <result name="sscat2p1InitConsid"

type="tiles">editShortSentenceCaseEvaluation</result>

</action>

 

I hope you got the sicenario , Its tofugh to explain whatz going on in the

mind !

 

Thanks

Siddiq.
