Marshal method is called multiple times on a single user task

[melissa.ferenal]

Hi,

I created my own marshalling class by implementing ObjectMarshallingStrategy  as suggested on this post How to persist session data.

But when I execute a user task the marshal method is called multiples times which tries to insert the data multiple times as well.

How can I limit the call to marshal to only once?

[swiderski.maciej]

it will call the marshaling for every variable. Does it call multiple times for single variable as well?

Anyway, your marshaling strategy should be capable to cope with both initial persist of the variable and updates as well. This is because engine will call it whenever it attempts to persist its state

Thanks Maciej for the reply.

I only have 1 data object(3 fields) assigned to a user task but it calls the marshal method 5 times after submission.

Actually, I've already enabled my marshalling strategy to handle updates when the record exists but I was just curious about the number of times the marshalling method is called after submission since I may have to send a REST request every time the data is created or altered.

that should not happen, I'll take a look and write a test to make sure that single variable is persisted/updated only once. If you have a standalone reproducer then please file a jira with it as that will make the investigation way faster.
