StackOverflow error occurs when opening Recursive Structure with Visualization in Tree Picker of Process Plan Browser in WIndchill MPMLink 12.0.2

Modified: 21-Jun-2022   


Applies To

  • Windchill MPMLink 12.0

Description

  • StackOverflow error occurs when opening Recursive Structure with Visualization in Tree Picker of Process Plan Browser
  • When this occurs, new Methodserver instance restarts and existing pages in browser are not responsive
  • New tab (or browser restart) is successively required in order to access back Windchill PDMLink/MPMLink environment
  • This impacts recursive structures created with the following logic:
    1. SUB assembly assembled in TOP assembly in a BOM Transformer
    2. ASSY assembly assembled in SUB assembly
    3. ASSY Assembly opened as top object in a new BOM Transformer
    4. SUB Assembly assembled as a child of ASSY assembly
    5. This leads therefore in following structure when TOP assembly is opened as top assembly object in Product Structure Browser

  • Issue consequently occurs when similar above Recursive structure with Visualization is then opened in Tree Picker of Process Plan Browser
  • Exception in Methodserver log as follows:
