There is a bug in the DSL parser: after '=', a couple of variable
references merely separated by a period isn't recognized.
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}
