hi joanneh
in documentation mentioned that
"Creating an expression in rule event that does not evaluate to true or false causes the expression to be automatically set to false".

Indeed, the real case in my situation should be

=isusermemberofgroup(

username:pv!user,

groupId: 23

)

What i am curious about is that why "the function with a pv!" doesnot work in a rule event

Setup below expression in Rule Event
isusermemberofgroup(pp!initiator, 23)

It will work...

Hello,

First of all you don't need to wrap boolean function into if(), you can use isUserMemberOfGroup() directly. It should work.

The error you have because this node is not user input and loggedInUser() doesn't return a correct value for isUserMemberOfGroup().

As I understand your scenario should wait until some user will be added into a group in case he is not yet a member. In this case the user should be saved into a process variable and passed as a parameter into isUserMemberOfGroup(). The problem here is that the rule is reevaluated when a process variable changes and changing membership will not update process variable. So you need some additional pieces to have it reevaluated after membership changed.

hi joanneh use script task before the rule event in that script task give your expression as output and save it in a Boolean process variable(pv!result),
then in your rule event configure condition as result=true().

Then instead of using rule event, I suggest to use script task.

Thanks. I have checked it before.

What confuse me is it doesn't event work for a simple rule expression like this....

I wish to use your way too...

However, the real case in my situation should be

=isusermemberofgroup(

username:pv!user,

groupId: 23

)

where the pv!user is keep updating within the process model.

If I have to save the function result beforehead, I have to create a loop until the function result returns true; Unlimited looping itself may induces another problem...

For rule event condition to work store the value returned by this condition
isusermemberofgroup(
username:loggedInUser(),
groupId: 23
)
in a process variable, Then select the operator as equal to(=) and give the value as true in the text-entry field.

Seems like It is not working either....

if(
isusermemberofgroup(
username:pp!initiator,
groupId: 23
),
true,
false
)
once try with this Expression rule,replace loggedInUser() with pp!initiator

please check the below link:
docs.appian.com/.../Rule_Event.html

Dear Santosh Kumar D,

Thanks for helping, this is the way I do it:

"if(isusermemberofgroup( username:loggedInUser(), groupId:23),true,false)"

and when I use a script task node to check the returned value from the above rule, it returns "true" as boolean; but it does not work in the rule Event node

Hi joanneh,

The rule event evaluates to true iff the condition you specified to be true, then the flow be continued in the process flow.
With your inputs(Screenshots) it's harder to say what is wrong in the rule. Can you provide the configure screenshot??
