[rules-users] Guvnor 5.5 bug - when the advanced enum feature is used, the selected value is not saved in special condition

When there are 3 drop downs, one determines the values of the other, the selection in the last drop down is not saved when changing the rules twice in the row. For example: I have the following statement: in fact [field1] [field2][field3] each of the field is presented as a drop down by using the advanced ENUM feature - 1 determines the values in 2 and the selection of 2 determines the value of 3. After the value in field3 is selected, I can move on and make the changes in the rule. When the first change occurred, Guvnor remembers the values being selected in all 3 fields. But when another change is make, the selected value in the last field (field3) will be forgotten. Please note this is only happening to the last field. I did not go further and make the statement contain more than 3 drop downs. I have tested this several times and am confident this is a bug in the 5.5 final version. Thanks Sean
