Document contains screenshots and steps to reproduce the issue.

Description of problem:
In Guided Rule Editor, customer is trying to add expression for variables (String type) using replace or replaceAll condition parameters. 

After saving, closing and reopening same rule in guided rule editor, string expressions are missing.

Version-Release number of selected component (if applicable):
BRMS 6.1.0

How reproducible:

Steps to Reproduce:
1. Create a Project using Business Central and import the fact which contains string variable.

2. Create one Guided Rule by using that imported Fact

3. Use the fact and String variable of that fact. (as per attached project, used TestVO)

4. Apply replace condition on the string variable with some expression and rule looks like below:

~~~
import com.org.redhat.TestVO;

rule "Replace_condition_Issue"
     dialect "mvel"
     when
          TestVO( $cts : test.replace("+",""))
     then
end
~~~

5. Save the guided rule, close it and try to reopen same rule.

6. Expressions from replace condition has been removed.

Actual results:

There should be no change in the rule while reopening it. It should be as it is with whatever parameters have been configured in replace condition.

Expected results:

After reopening the rule in guided rule editor, expressions from replace condition has been removed.
