Problem defining form for workflow task

[amitev]

Hi all! I am creating my own workflow and defined a form for the start workflow and the transition to the next task is successful. But when I open the second task for Edit instead of the default form I get the following error on the web page:

An error has occured in the Share component: /share/service/components/form.
It responded with a status of 500 - Internal Error.
Error Code Information: 500 - An error inside the HTTP server which prevented it from fulfilling the request.
Error Message: 04030000 Failed to process template org/alfresco/components/form/form.get.html.ftl
Server: Alfresco Spring WebScripts - v1.0.0 (Release Candidate 2 744) schema 1,000

Idea what am I doing wrong and how to fix that?

[amitev]

After some debugging i found that the exception is thrown in the following code in alfresco/WEB-INF/classes/alfresco/templates/webscripts/org/alfresco/repository/forms/formdefinition.lib.ftl:

        "formData":
        {
            <#list form.formData?keys as k>
            <#if form.formData[k]?is_boolean>
            <#– Render boolean data without the surrounding inverted commas –>
            "${k}": ${form.formData[k]?string}<#if k_has_next>,</#if>
            <#elseif form.formData[k]?is_number>
            <#– Render number data without the surrounding inverted commas and no formatting –>
            "${k}": ${form.formData[k]?c}<#if k_has_next>,</#if>
            <#else>
            <#– All other data rendered with inverted commas –>
            "${k}": "${form.formData[k]}"<#if k_has_next>,</#if>
            </#if>
            </#list>
        }
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

The json that is saved in the model for the view ftl is the following:

{
   "formData":{
      "prop_bpm_packageActionGroup":null,
      "prop_bpm_packageItemActionGroup":null
   },
   "item":"api/task-instances/jbpm$4",
   "type":"sirmawf:DRAReviewTaskAndDocument01",
   "submissionUrl":"/api/task/jbpm$4/formprocessor",
   "fields":[
      "org.alfresco.repo.forms.PropertyFieldDefinition@1adc141 (name=sirmawf:DRANeedSMETeamForReview, dataType=boolean, dataTypeParams=null, label=sirmawf:DRANeedSMETeamForReview, description=null, binding=null, defaultValue=null, dataKeyName=prop_sirmawf_DRANeedSMETeamForReview, group=null, protectedField=false, mandatory=true, repeats=false, constraints=null)",
      "org.alfresco.repo.forms.PropertyFieldDefinition@6acfc9 (name=sirmawf:DRAApproveDocument, dataType=boolean, dataTypeParams=null, label=sirmawf:DRAApproveDocument, description=null, binding=null, defaultValue=null, dataKeyName=prop_sirmawf_DRAApproveDocument, group=null, protectedField=false, mandatory=true, repeats=false, constraints=null)"
   ]
}
[/code]

And the problem comes when formData array is iterated where the values are null. But still I have no idea what I am doing wrong.‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Rather than trying to debug your problem from the exception traces it would be better to post the configuration you've changed and start from there.

Thanks,
Mike

I have share-config-custom.xml.

<config evaluator="task-type" condition="sirmawf:DRAReviewTaskAndDocument01">
      <forms>
         <form>
            <field-visibility>
               <show id="sirmawf:DRANeedSMETeamForReview" />
               <show id="sirmawf:DRAApproveDocument" />
            </field-visibility>
            <appearance>
               <set id="" appearance="title" label="Tralala" />
               <field id="sirmawf:DRANeedSMETeamForReview" />
               <field id="sirmawf:DRAApproveDocument" />
            </appearance>
         </form>
      </forms>
</config>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Here is the data model:

<type name="sirmawf:DRAReviewTaskAndDocument01">
         <parent>bpm:task</parent>
         <properties>
            <property name="sirmawf:DRANeedSMETeamForReview">
               <type>d:boolean</type>
               <mandatory>false</mandatory>
            </property>
            <property name="sirmawf:DRAApproveDocument">
               <type>d:boolean</type>
               <mandatory>false</mandatory>
            </property>
         </properties>
</type>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

What other information should I provide?

[amitev]

It got fixed when i changed the parent of the task to bpm:workflowtask instead of bpm:task but I don't know why this was needed.
