To link documents from SharePoint to viflow, create a viflow information object and enter the path to the document in the Hyperlink field of the information's properties.

In SharePoint, make sure that the link is not changed by document updates.
This way, you always have the advantage to access the current version of the document in SharePoint.

It is not possible to simply copy the link directly from SharePoint because it displays URL encoding like %20 instead of spaces.
Such a link cannot be opened properly later in the WebModel.

To work around this problem, all links with this encoding must be edited after they have been pasted into viflow.
Replace all %20 with spaces.
