[jboss-jira] [JBoss JIRA] (DROOLS-467) Decision tables: parsing an xls throws an IndexOutOfBoundsException, but it should throw a better error message (including the invalid cell in the xls

[Geoffrey De Smet (JIRA)]

    [ https://issues.jboss.org/browse/DROOLS-467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12962220#comment-12962220 ] 

Geoffrey De Smet commented on DROOLS-467:
-----------------------------------------

REPRODUCE RECIPE:
- Take a working XLS, for which the first ACTION column has a empty cell directly below the ACTION cell.
- Take the CONDITION column before that first ACTION column and expand the cell directly below the CONDITION cell, which holds the class name, by merging it with the cell below the ACTION cell.

Alternative:
- Just try to parse the DRL above - it should give a better error message than the IndexOutOfBoundsException.
