Default filter - Value may not be longer than 1,000 characters. You have entered 1,109 characters.

It sounds like you're writing your Expression Rule directly into the box, like this:

This is not good practice. All such Rules should be encapsulated in their own rule - e.g. XXX_ER_defaultFilterForMyRecord() where they can be tested (and changed!) independently of where they're used (that is you shouldn't have to add them to the Record first in order to know whether it's working or not!). This should also solve the character-limit issue.

Thank you @Stewart Burchell for the response. I pass all the filters as an expression rule, and fixed my problem and also the character-limit issue.
