<method-result> "scope" attribute query

[spring_field]

This web flow state produces the exception below; the problem is scope="flow" on the <method-result> element. Without it the flow executes. Thanks.

<action-state id="lookupIssue">
<bean-action bean="issuesManager" method="getIssueById">
<method-arguments>
<argument expression="${flowScope.id}"/>
</method-arguments>
<method-result name="issue" scope="flow"/>
</bean-action>
<transition on="success" to="viewIssue"/>
</action-state>

Which id youn are expecting as a parameter

[sriramy]

You can just try this as follows

<view-state id="currentState" view="currentView">
<transition on="currentEvent" to="currentSubFlow" >
			<set attribute="id" value="${requestParameters.Id}" scope="flow"/>
		</transition>

</view-state>

<subflow-state id="currentSubFlow" flow="currentInlineFlow">
		<transition on="finish" to="someWhereUNeed" />
	</subflow-state>

<inline-flow id="currentInlineFlow">
		<flow>
			<start-state idref="currentFlow" />
			
			
			<action-state id="lookupIssue">
                          <bean-action bean="issuesManager" method="getIssueById">
                            <method-arguments>
                               <argument expression="${flowScope.id}"/>
                           </method-arguments>
                           <method-result name="issue" scope="flow"/>
                      </bean-action>
                    <transition on="success" to="viewIssue"/>
                </action-state> 
			<end-state id="viewIssue" />
		</flow>
	</inline-flow>

or u can try this way

<input-mapper>
        <input-attribute name="id"/>
    </input-mapper> 

   ...................

<view-state id="currentViewId" view="currentView">
        
	  <transition on="*" to="lookupIssue"/>	
	</view-state>
<action-state id="lookupIssue">
                          <bean-action bean="issuesManager" method="getIssueById">
                            <method-arguments>
                               <argument expression="${flowScope.id}" parameter-type="int"/>
                           </method-arguments>
                           <method-result name="issue"/>
                      </bean-action>
                    <transition on="success" to="viewIssue"/>
                </action-state>
<view-state id="viewIssue" view="sadf">
..........
</view-state>

In the jsp or any view u need to do as

<input value="Save" class="btn" name="_eventId_save" type="submit">
<input type="hidden" name="id" value="${model.id}" />
