Maximum path length exception error raised when starting web form action with web apps secure mode enabled


#1

When web apps secure mode is enabled, WorkflowGen will try to store web form runtime temporary files inside a GUID subfolder (36 characters length) for the current action.

 

In some cases, the generated path might exceed the Windows maximum path length of 260 characters. (See the Maximum Path Length Limitation section at https://msdn.microsoft.com/en-us/library/aa365247.aspx for more information.)

 

There are two workarounds:

  • Disable web apps secure mode in the Configuration panel.

    or

  • Make sure the web form storage path (e.g.\\SERVER\SHARE$\WfApps\WebApps\eFormAspx\App_Data) is as short as possible.
