Escape Character in Rules

Hi,

I am using a DSL sentence within the JBRMS like this:

[condition]There is an Instance with field of =i: Instance(field=='{value}')

When I enter a string for in the rules editor that contains a “{” it is not shown in the source code of the rule and saving of that rule is impossible. There is no Error Message, but the saving dialog in not closing.

So I wonder if there is any escape character, that I should use in the rule or is there something wrong with the DSL?

Cheers Tobi
