I want to start my workflow with a SharePoint Designer created Custom Action (ribbon button)

The steps I did were:

1. create workflow with

    Form Type = Custom

    Start Page = empty

2. create a custom Action "Start Workflow"


Then if i use the Action Button, I get an error


An exception occurred while rendering the Ribbon on the SharePoint Page.The following exception was thrown : System.ArgumentException: The Ribbon Tab with id: "Ribbon.Read" has not been made available for this page or does not exist. Use Ribbon.MakeTabAvailable().

    at Microsoft.Web.CommandUI.Ribbon.Render(HtmlTextWriter writer)

    at Microsoft.SharePoint.WebControls.SPRibbon.Render(HtmlTextWriter writer)


I'm not sure, what's wrong  - does anybody have an idea ?
