gllobal filed doesnt update

[#1]

hi i have a problem in general, the issue is that i created a global variable on TargetGroup.xbo this is how i declare the variable: element isRaiseErrorGlobal: LongText; and on event-root-beforeSave.absl i try to update the value of the field in a specific condition and then on event-root-validation onSave.absl i try to check if the value of this variable is equal to 1 i will return false; but actually i update the value of the field isRaiseErrorGlobal to 1 on the event-root-beforeSave.absl but the value doesn't save and when the code debug mode runs into the root-validation onSave.absl file i see that the value in the field didn't update and it's still empty it is very strange behavior because it should update the value in the field if i did so also, there is no line in the code which resets the field value I don't know how to deal with this matter and that is very important to me because that's the whole point of a validation box where you can check certain values that were updated during the lift and accordingly return true or false please, if it is possible to check the matter why saving data in the global field does not work as expected
