Visual Business Director fails to load data



Visual Business Director (VBD) fails with ArrayIndexOutOfBoundsException while loading a very small volume of data using the data source.

Error Messages

Following error is occurring when the Java Applet loads.

Caused By:
>>> Type: java.lang.ArrayIndexOutOfBoundsException
>>> Message: 6
>>> Stack trace:
>>> at com.pega.decision.vbd.service.engine.util.ColumnFamilyGrouping$2.groupValue(

Steps to Reproduce

1) Import data into VBD.
2) Launch the VBD Planner by clicking on the data source.

Root Cause

The Data Source was corrupted causing the reported behavior. Creating a new Data Source and writing the same data to it results in it being able to be used. There is one data source provided out-of-the-box that use the Interaction History tables as its source i.e. the ‘Actuals’ Data Source which is retrieved from Interaction History.


Additional Data Sets can be created that DO NOT use Interaction History as a Source of their data. In both Pega 7.1.9 (GridGain) and Pega 7.2 (Cassandra) a VBD DataSet other than “Actuals” results in the data being stored in the attached file system.
