Generating documents from SharePoint Designer workflows

Hi jcgonzalezmartin,

I was using the 2013 workflow engine. I did some testing this morning with the equivalent 2010 steps and my results are not great. 

1. when I configure a custom document library with a custom content type and I set the content type inside the workflow then I'm getting:

The workflow could not create the list item. Make sure the list exists and the user has permissions to add items to the list.

2. When I set the content type in the workflow to the out of the box "Document" then the workflow creates a document successfully.

3. Then I tried with a custom document template on the library and even though the document is created the document fails to open complaining about the content. 

So it looks like I can't use custom content types.
