      1. when you edit one of the attributes (consider "from" attribute), if you try copy the expression "#

      {MailingVar.from}"
      2. than you try switching to Data Item instead of Expression selected
      3. again switch back and select Expression and paste the copied expression "#{MailingVar.from}

      " in Script
      4. further you will observe that all four mapping error which was visible under problem tab disappears when you save the process.

      However if you try again updating your project (Maven -> Update project), again same error comes back and requires to be re-mapped[3] again to remove the errors.

      > consider you have maven project having bpmn process with custom task (Email task)
      > than set below expressions in Attributes for Email task where WorkItemDefinition contains [1] :

      From :: "#

      {MailingVar.to}

      When you set expressions instead of using "Data Item and assigning Source" for Custom task (such as Email task created) in process , throws error "Data Input From has no Data Type", similarly for other attributes:

      "Data Input To has no Data Type"
      "Data Input Subject has no Data Type"
      "Data Input Body has no Data Type"

      If we have WorkItemDefinition having content as below:

      [
      "name" : "Email",
      "parameters" : [
      "From" : new StringDataType(),
      "To" : new StringDataType(),
      "Subject" : new StringDataType(),
      "Body" : new StringDataType()
      ],
      "displayName" : "Email",
      "icon" : "defaultemailicon.gif"
      ],
