A new web application security feature has been included since version 5.6.1 to protect the integrity of the workflow parameters exchanged between the WorkflowGen Portal and the web form.
Web apps secure mode activation is defined in the new Security section on the General tab in the Configuration Panel.
Note: When web apps secure mode is enabled, all of your Visual Studio Web Forms must have both Assembly files upgraded accordingly. Otherwise, the web form will raise the .NET error Unable to read the form data from the XML file.
The requirements for existing clients with Visual Studio-based webforms are:
WorkflowGen version 5.6.3 and earlier
Upgrade WorkflowGen.My.dll and WorkflowGen.My.Web.UI.WebControls.dll to version 2.3.4 in your Visual Studio Web Forms \bin folder.
WorkflowGen version 5.6.4
Upgrade WorkflowGen.My.dll and WorkflowGen.My.Web.UI.WebControls.dll to version 2.3.5 in your Visual Studio Web Forms \bin folder.
WorkflowGen versions 5.7.x and 6.0.x
Upgrade WorkflowGen.My.dll and WorkflowGen.My.Web.UI.WebControls.dll to the same version found in your WorkflowGen \wfgen\WfApps\WebForms\Bin subfolder.
