Logic map not visible in EngageOne Designer

Product Affected: EngageOne Designer
Product Feature: Designer - Logic Map
Versions affected:  All V5 and V6

Issue

The logic map is no longer visible:
User-added image

 

Cause

During a resize operation, the pane sometimes gets set to a negative value which causes the resize controls to be rendered outside the window area. This makes them inaccessible.

The invalid size gets saved in the registry.

Resolution

UPDATED: August 23, 2019
To solve the problem of the logic tree disappearing, follow these steps:
  1. Ensure Doc1 Designer is no longer running on your machine (exit the program)
  2. Start RegEdit (Start Menu->Run, then enter "regedit")
  3. Find the path: "HKEY_CURRENT_USER\Software\Group1\DOC1 Series\5.1\Doesvr\Settings" and look for the key: "LogicMapWidth"
  4. It will most likely have a negative value; set it to a new value like "100".
 Designer should now work normally.



Note: At the end of 2019, Microsoft is ending support for the Windows 7 operating system along with a number of the older versions of Microsoft SQL. No version of EngageOne Server lower than 4.4 or Designer/Generate version lower than 6.6 will still be fully supported. Please see release notes for full details.
