Hi Michael,

I just discovered ActionType.addNewActionType, where the code tries to follow some
(now) completely undocumented principle, where columns can be identified by single
letters, the first one of the action type. This is in conflict with the documentation,
where only full-fledged keywords are permitted.

There are some undocumented keywords, e.g., DESCRIPTION. Using this results
in a duration attribute (which is deprecated anyway). This can be fixed, but then
the description is entered "as is"; it should have a leading '#'.

Clear out all undocumented things? Or fix them properly and document them?

What is it to be?

nice work.. 
yes "syntax cushioning" is the best term I have heard for this. 

I am sure your enhancements would be welcome.

As one of the incentives (perhaps the main one) for this kind of rule authoring appears to be a "syntax" cushioning by spreadsheet entries, I feel that additional simplifications might be appreciated. Therefore, I have modified some classes in  org.drools.decisiontable.parser, to achieve the following, in the area of RuleSet entries:
  • All entries are now repeatable, either by adding more cells to the right of "import" than just one (with a comma-separated list) or by writing more that one "Import" row.
  • Same for "Variables", "Functions" and "Queries".
  • All tags ("Import",...) are case insensitive and immune against leading and trailing spaces.
  • Some user errors don't cause NPE; they throw an exception with an explanatory message
Opinions, please, and should I just release this, or would someone care to have a look and test it?
