How to resolve “The workflow template has specified no FormURN for this page” error if you do not use any forms for the workflow.

When creating a Workflow project, by default, I insert a workflow.xml snippet with something like this:

 

   1:  

   2: <Elements xmlns="http://schemas.microsoft.com/sharepoint/">

   3:   <Workflow

   4:        Name="My Workflow"

   5:        Description="This workflow ..."

   6:        Id="GUID"

   7:        CodeBesideClass="ProjectName.Workflow1"

   8:        CodeBesideAssembly="ProjectName, Version=1.0.0.0,

   9:          Culture=neutral,

  10:          PublicKeyToken=publicKeyToken"

  11:        TaskListContentTypeId="0x01080100C9C9515DE4E24001905074F980F93160"

  12:        AssociationUrl="_layouts/CstWrkflIP.aspx"

  13:        InstantiationUrl="_layouts/IniWrkflIP.aspx"

  14:        ModificationUrl="_layouts/ModWrkflIP.aspx"

  15:        StatusUrl="_layouts/WrkStat.aspx">

  16:  

  17:     <Categories/>

  18:     <MetaData>

  19:       <AssociateOnActivation>false</AssociateOnActivation>

  20:     </MetaData>

  21:   </Workflow>

  22: </Elements>

  23:  

Usually I don’t have any forms associated with the workflow, after deploy the workflow, I will get the “The workflow template has specified no FormURN for this page.” error.

To resolve this, just remove the TaskListContentTypeId, AssociationUrl, InstantiationUrl, ModificationUrl properties of the workflow and redeploy the workflow. 

   1: <Elements xmlns="http://schemas.microsoft.com/sharepoint/">

   2:   <Workflow

   3:        Name="My Workflow"

   4:        Description="This workflow ..."

   5:        Id="GUID"

   6:        CodeBesideClass="ProjectName.Workflow1"

   7:        CodeBesideAssembly="ProjectName, Version=1.0.0.0,

   8:          Culture=neutral, 

   9:          PublicKeyToken=publicKeyToken"

  10:        TaskListContentTypeId="0x01080100C9C9515DE4E24001905074F980F93160"

  11:        AssociationUrl="_layouts/CstWrkflIP.aspx"

  12:        InstantiationUrl="_layouts/IniWrkflIP.aspx"

  13:        ModificationUrl="_layouts/ModWrkflIP.aspx"

  14:        StatusUrl="_layouts/WrkStat.aspx">

  17:     <MetaData>

  18:       <AssociateOnActivation>false</AssociateOnActivation>

  19:     </MetaData>

  20:   </Workflow>

  21: </Elements>
