Hello Edson,

       If the generic *<T>* is not allowed, and drools appears to be written to
operate over collections of objects, how do you insert a List of items like
this:
*List<ProjectDataSet.Task> tasks*?  In my code I insert the tasks as facts
like this:
*commands.add(CommandFactory.newInsertElements(tasks));*
I use a decision table and have as one of the variables: (in the variable
row)
*List<ProjectDataSet.Task> tasks*.

       The error I receive is this:
/org.drools.template.parser.DecisionTableParseException: The format for
global variables is incorrect. It should be: [Class name, Class otherName].
But it was: [List<ProjectDataSet.Task> tasks]
       at
org.drools.decisiontable.parser.RuleSheetParserUtil.getVariableList(RuleSheetParserUtil.java:84)/

       I desire the rules in the table to iterate through all the tasks in that
list and identify tasks that are due soon (a part of my condition column
*TASKACTSTART< today* … etc.  The TASKACTSTART is a field named by Microsoft
in the ProjectDataSet.Task class.)

       Have I misunderstood the power of drools?  How do you address a collection
of a type like List<T> in a rule?

Thank you in advance for your help,
       Adrigan
