<p class=MsoNormal style='margin-bottom:12.0pt'>The operators "in"
and "not in" operate on parenthesized lists of operands. They can be
used with a single template parameter expanding as a list.<br>

<p class=MsoNormal>I have successfully generated a .drl file from a decision
table. The column headers in this table made use of the forall(||) construct
which happily parsed the corresponding comma separated data in the relevant
spreadsheet cell to nice || separated conditions.<br>
<br>
We have since decided to use the template approach so we can store rule data in
a db. We ideally want to store this data as key/value pairs in a db table where
the values may contain comma separated data. The intention being these values
would be processed as per the decision table.<br>
<br>
How is this achieved using a template ? I note that a column can be denoted as
an array column by adding [] i.e.<br>
<br>
template header<br>
column[]<br>
<br>
<br>
However, although this appears create an ArrayColumn parser, and splits the
comma separated data when running through a debugger, any attempt to access it
in the template falls over in mvel code trying to call HashMap.column<br>
<br>
<br>
Any examples on how to set this up ?<br>
<br>
Thx<br>
