[rules-users] Regular expression problem in .dsl

[FrankVhh]

Hi,

The placeholder will just be replaced by whatever the user input is, there
is no need to do those String operations.

In your dsl, copy your DRL and replace everything that is user input by
{keyword}. Nothing else has to be done.

Regards,
Frank
