WAM Editor not displaying design view on Windows 8.1

Product/Release:Visual LANSA - V13 and above
Abstract:WAM Editor not displaying design view on Windows 8.1
Submitted By:LANSA Technical Support
Updated:26 November 2015

Update:

This technical article previously described this as a problem that could occur on Windows 8.1 32-bit only. This issue has subsequently been confirmed as occurring on both 32-bit and 64-bit Windows 8.1 operating systems and the article has been updated to remove references to 32-bit only.

Description:

Using the WAM editor in Windows 8.1 can generate an error when trying to open the design view and the design will appear blank.

LANSA Editor error

Blank Design

Cause:

This is caused by Visual LANSA not having authority to write to %temp%. This location is where the WAM Editor is trying to create temporary cache files.

Solution:

The solution is to set Visual LANSA to always run as administrator. This will mean that Visual LANSA has full premissions to read and write to the %temp% location.

Development Environment Properties 

The Design is now visible

Note:

  • This issue can affect both 32-bit and 64-bit versions of Windows 8.1. The same solution can be attempted for both versions of Windows 8.1.
  • If this change does not resolve the issue, WAM Editor logging can be enabled by creating a file called wamed.def in the folder  <LANSA>\LANSA\WAMEditor, (where <LANSA> is the LANSA environment root folder) and adding the following script to it

    [trace]
    groups=*ALL


    Send the resulting log (found in %Temp%\wamed\<006044>\trace\wamed.log) to LANSA Support.
