edgeCore Known Issues

Bootstrap 4 Updates

Due to the significant upgrade to Bootstrap 4, systems with customizations in the following areas should be tested to determine if they will require updates:

  • HTML Template Visualizations
    • Example 1: Glyphicons are no longer included. If you have custom HTML Templates that used them, in v3.11 they will all be empty.
    • Example 2: EC-204 – updating theme theme=”bootstrap” to theme=”bootstrap4-1″
  • Login Pages
  • Themes

Common Table Expression ‘WITH’ Clauses

edgeCore uses the H2 database in support of the SQL Transforms. SQL that uses Common Table Expression (CTE) ‘WITH’ clauses have been identified as causing two issues.

  1. Lock Timeouts: Transforms fail to run as temporary tables fail to be cleaned up.
  2. Memory Leaks: The temporary table results are not being cleaned up properly in all instances, and it will trigger Out Of Memory on the JVM.
