Select assignee button does not appear

[acgrama]

I have created a very simple workflow, and it is deployed correctly. However, when I start the workflow, I cannot select an assignee, because the "select" button is not rendered on the page (see attached screenshot).
My Alfresco version is 4.2.a.

I have copied the process definition (bc2process.bpmn) and workflow context (bc2process-workflow-context.xml) to this folder: \alfresco_4.2.a\tomcat\shared\classes\alfresco\extension

The files:

bc2process.bpmn:

In \alfresco_4.2.a\tomcat\webapps\share\WEB-INF\classes\alfresco\share-workflow-form-config.xml, I have added the following, to customise the form:

…
   <config evaluator="string-compare" condition="activiti$bc2process">
      <forms>
         <form>
            <field-visibility>
               <show id="bpm:assignee" />
               <show id="packageItems" />
            </field-visibility>
            <appearance>
               <set id="" appearance="title" label-id="workflow.set.general" />
               <set id="info" appearance="" template="/org/alfresco/components/form/2-column-set.ftl" />
               <set id="assignee" appearance="title" label-id="workflow.set.assignee" />
               <set id="items" appearance="title" label-id="workflow.set.items" />
               <set id="other" appearance="title" label-id="workflow.set.other" />
               <field id="bpm:assignee" label-id="workflow.field.assign_to" set="assignee" />
               <field id="packageItems" set="items" />
            </appearance>
         </form>
      </forms>
   </config>
…

EDIT: I cannot edit the Tags, as nothing happens when I type in the text field.

Tell me make your model first and if you are using exiting model,no need to deploy this model again you can use it.
i am giving you my email id send me your code to me and i will ractify it.
Your BPMN also have errors
1.  <startEvent id="eventStart" name="Start"></startEvent> ,here define the formkey that you want to disply
e.g. <startEvent id="eventStart" name="Start" activiti:formKey="wf:submitAdhocTask" /

if it not working mail the code

Hello
I note you're using bpm to deploy your workflow, in my case i'm using activiti and have the same problem, the select assignee button doesn't appear.
I use 3 archive configurations:

The workflow deploys successfully, but when I want to run it in the interface the assignee button doesn't appear like in the picture attached  show
please, any help is welcome!

[cool123]

see your model,
1. model
—————————-
<type name="wfge:startSopReview">

         <parent>bpm:startTask</parent>

         <mandatory-aspects>

         <aspect>bpm:assignee</aspect>

         </mandatory-aspects>

      </type>
you shoud use bpm:assinee in start task as a mandatory aspect.
This is the one mistake

2. share config file
