Re: [rules-users] pattern
rule "PatternTest"
when
$pli:Item( eval(title.matches("^Test\s*")) )
then
#
end
Having a second look i realize that the DroolsParser should not parse
the pattern string because it's java code ... and i can't use title
matches "^Test\s*" because title may have chars like (,\ and so on
that resolves into a RuntimeException (sth. with Groups not closed in
RegEx).

that regexp is a String, but variables that resolve to a valid regexp are
also allowed. It is important to note that different from java, if you write
a String regexp directly on the source file, you don't need to escape '\'.
