** I have the following Drools DSL "sentence": [when]The field {field} in the module {module} contains value {value}=$a : {module} ( {field} != null) String( this.equalsIgnoreCase("{value}") ) from $a.{field} where the `field` is a `Set` of Strings. Now, if I have two of these sentences in one rule, it obviously won't work as the variable `$a` occurs twice. So I wanted to improve the rule to make the variable, well, variable: [when]The field {field} in the module {module} contains value {value} as {a}={a} : {module} ( {field} != null) String( this.equalsIgnoreCase("{value}") ) from {a}.{field} This doesn't work, I can't use the part `{a}.`, that breaks. So, my questions are: Is there either a way to rewrite the rules or a way to allow the `{variable}.` notation to work? Alternatively, is there a `contains` operator which works case insensitive?

There is no expanded DRL. If I take that line into the DSL, I can't even validate the DSL and if I have the line in it, I can't select any DSL statements for rules in Guvnor.

Hello Wolfgang, hello everybody, Nice one, thanks for the idea! This one works for now, but is there a way to automatically assign random variable names to the RHS of the DSL? So the user won't have to explicitly set a variable in the DSL which is only needed for internal purposes.

As a workaround, use this: [when][]The field {field} in the module {module} contains value {value} as {abc} = {abc}x : {module} ( {field} != null) String( this.equalsIgnoreCase("{value}") ) from {abc}x.{field} -W On 12/06/2012, Sandjaja, Dominik <dominik.sandjaja(a)it-motive.de&gt; wrote: > There is no expanded DRL.
