When embedding the viflow WebModel in SharePoint, a basic distinction must be made between the WebModels of viflow 6 and ViFlow 5.
The procedure for both versions is explained below:
Integration of a viflow 6 WebModel:
Your WebModel can already be stored on a WebServer or has been stored in a document library of SharePoint (With SharePoint 365 no longer possible!).
Then create a new page-viewer webpart and link it to the start page (index. htm) of the stored WebModel.
Integration of a ViFlow 5 WebModel:
The integration of the ViFlow 5 WebModel is the same as for the viflow 6 WebModel, but with the following exception:
To view the ViFlow 5 WebModel in Internet Explorer we need the compatibility setting for IE 8, but in SharePoint 2010 and higher we use higher compatibility. WebModel display is only possible if the compatibility settings in the SharePoint Masterpage are reduced. This may cause display problems with other SharePoint elements.
Problem with HTML files downloaded from SharePoint and not opened directly:
If an older version of SharePoint is used (2007,2010 or 2013) the download can be prevented:
To do this, change the "Browser File Handling" option in the General Settings of the Web application in SharePoint's central administration. By default it is set to "Strict" and must be changed to "Permissive".
