Expression Rule timer logic?

Hi Narmada,

Appian does not provide feasibility to develop such logic using SAIL/expression rules, however you can try using timer event in process model.
Thanks

No way. Because, before an expression displays line1 and line2, its evaluating line1 and line2 first then its displaying in the output. Observation:I tried to keep system busy by generating nulls in which will take 25,734 ms after line1 and before line2. Its taking total time to evaluate (line1+null generation+line2) to present the output. This means the expression prepares everything before it presenting.

One thing no one is mentioning in this, if you're using this in SAIL you're not going to be able to do it. You can't kick off a process without some sort of user interaction. You either need a start process link for the user to get to another process with timer, and the user will have to click for timer to start. Or you will have to submit the form to continue in the same process model and reach timer event. That also can only happen on user click.

If you want the form to display something, then a second later display something else automatically, it's most likely not going to happen with any current version.

Hi Narmada,

This is not possible in appian u can not put timer in expression rule because the whole expression logic is executed at once only.
U need to handle this in process.

Hi Narmada,
This is not possible with rules in appian. so could you please give more details where you want to implement it and what is the scenario/use case.

Thanks

Hi Narmada,
There is no such workability to do with your case,I propose you to go with timer event i.e, through process model and that makes the work easier too.According to your requirement you can also use a timer condition.Based on condition you provide the values get evaluated.Make sure the timer events starts only if the compared values are true. Comparision is done against process variables.
Kindly go through this link:

Hi,
This is not feasible in Appian however if you want to have some delay between algorithms then you could implement it through a process model where a timer event would serve your purpose.

This is not possible. What is your use case?

Hi Narmada,

As per my understanding, we can not execute a expression rule on timer basis, the whole expression logic is executed at once only. We use this timer logic in process model from node to node.
