why? Nuxeo doesn't show workflow tab when type document is Folderish

Nuxeo doesn't show workflow tab when type document is Folderish. I need show this tab in my case

Workflow is enabled by default only on two document types: File and Note. This does not mean however that it cannot be enabled for other document types.

To enable the workflow on other document types please use these instructions: Enable workflow on your document type

Please note that Folderish refers to a facet, not a document type, and the procedure in the link above provides workflow association with document types.

Now when the workflow is enabled you can activate/display the "Workflow" tab on your "Folderish" documents:

<extension target="org.nuxeo.ecm.platform.actions.ActionService" point="actions">
  <action id="TAB_CONTENT_JBPM" link="/incl/tabs/document_process.xhtml"
     enabled="true" label="action.view.review" icon="/icons/file.gif"
     order="60">
     <category>VIEW_ACTION_LIST</category>
    <filter id="jbpm-process" append="true">
      <rule grant="true">
	<facet>Folderish</facet>

Afterwards you'll need to associate specific workflows to be available for the required document types (please note I'm listing here document types, not facets - this is because the default JbpmService filter operates on types - however you still could rewrite the default filter):

<extension target="org.nuxeo.ecm.platform.jbpm.core.JbpmService"
   point="typeFilter">
   <type name="Folder">
     <processDefinition>review_parallel</processDefinition>
   </type>
<type>
...

The last important thing to do is to provide the "require" clause to make sure your workflow/tab definitions are not overridden by those defined in another extension.

Indeed, that piece of documentation specifies only how to activate a workflow on a document type but does not add the tab to the ui. (because of the way this tool works, let me just modify my answer to include the missing information)

[Anahide_Tchertc]

you don't need to override the action, overriding the filter definition is enough

you're right
