Suspending the workflow at particlalar condition

Hi,I am currently customizing the submit_processdefinition.xml to our needs.I need to have a validation java hook(action or decision handlers) at a specific point in the workflow process which will validate the condition and if returns success the submit process will continue normally.If it fails,

One possible approach would be to put some sort of "validation failed" state into your workflow.

Hi rogers,

Can u tell me how can i use validation in state instead of using it in transition..?


<process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="wcmwf:CRsubmitNew">

    <swimlane name="initiator"/>

    <start-state name="start">  
       <task name="wcmwf:submitReviewTask" swimlane="initiator"/>
      <transition name="" to="Validation">
      <action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
                 <script>
                       var mail = actions.create("mail");
                                mail.parameters.to = 'santhosh.sekar@yahoo.com';
                       mail.parameters.subject = "Adhoc Task 123";
                       mail.parameters.from = 'santhosh.sekar@gmail.com';                  
                       mail.parameters.template = companyhome.childByNamePath("Data Dictionary/Email Templates/new.ftl");     
                       mail.parameters.text = "It's done end ";                               
                       mail.execute(bpm_package);
                </script>              
            </action>      
       </transition>  
    </start-state>
         
  <decision name="Validation">             
       <handler class="com.sample.action.MessageActionHandler"></handler>   
         <transition name="trEnd" to="end"></transition>

Hey rockycres,
I've read your case, and a question came into my mind!
Where have you added the following code?

        FacesContext fc =FacesContext.getCurrentInstance();                          
                       fc.getApplication().getNavigationHandler().handleNavigation(fc,null, "dialog:submitSandboxItems");
                       Utils.addErrorMessage("DOing SomeThing WronG");‍‍‍

and in your workflow what do these lines do?

    <event type="process-end">
         <action class="org.alfresco.repo.avm.wf.AVMRemoveAllSrcWebappsHandler"/>
        <action class="org.alfresco.repo.avm.wf.AVMReleaseTestServerHandler"/>
        <action class="org.alfresco.repo.avm.wf.AVMRemoveWFStoreHandler"/>
    </event>‍‍‍‍‍

would you explain me a little more about how to print the error message in the same page?
thanks,

FSB

Hi,
Good question…
#1.         FacesContext fc =FacesContext.getCurrentInstance();
             fc.getApplication().getNavigationHandler().handleNavigation(fc,null, "dialog:submitSandboxItems");
             Utils.addErrorMessage("DOing SomeThing WronG");

These lines are added in my custom action handler class .In my case ,when user submits the content,this handler class will validate few things and if fails it goes to end state & throws this error message in the same page…

    <event type="process-end">
         <action class="org.alfresco.repo.avm.wf.AVMRemoveAllSrcWebappsHandler"/>
        <action class="org.alfresco.repo.avm.wf.AVMReleaseTestServerHandler"/>
        <action class="org.alfresco.repo.avm.wf.AVMRemoveWFStoreHandler"/>
    </event>
These lines just removes & release all the handles to the current WF instance .

And if u want to display the error message in the same page ,get current facecontext,and just call handlenavigation method and pass the 3 args(currentfacecontext,[not mandatory],outcome)…Here outcome is the same page…In this case ,"dialog:submitSandboxItems" is the page name(dialog name)…

So it wll display the same page again and adderrorMessage("    ") will just add the errormessage to the UI..Hope this clears ur doubt…Thanks
