LogicBlox 4.8.2

Release Date: January 8, 2019

Corrected Issues

The issues listed below have been corrected since the 4.8.1 release:

  • Modeler
    • The copy/paste of empty (no fact) entity type values now works as expected. This includes both single and multiple positions copied, with the blank cell or cells anywhere in the values copied.

    • Fixed a Javascript error (AssertionError) that could occur on views showing position only metrics on ALL.

  • Tools and Services
    • Fixed a bug that could cause prefix-join with lookup to produce incorrect results and have degraded performance during incremental maintenance when domain parallelism is being used.

    • Fixed a problem in alpha trees where certain data sets would be highly compressed and in some cases could cause invalid alpha tree internal structure. The problems would be reported as unexplainable functional dependency violations during execution of LogiQL rules.

    • lb-workflow tasks that parsed JSON (like lb.ParseJsonObject) previously produced runtime exceptions if a field contained an empty string. This has been fixed and empty string field values are now supported properly.

Known Issues

The issues listed below are known to exist in the 4.8.2 release:

  • Tools, Database, and Services
    • This release contains changes to some lb-workflow tasks related to workbook creation. These fixes have not been applied yet to lb.wb.CreateWorkbook, which means errors related to recent changes in the LB runtime that imposes restrictions on string lengths can still occur. Please note that this known issue does apply to lb.wb.util.CreateWorkbook.
