Issue with Parallel multi instance not processing all items

m.issoulghane · July 25, 2024, 9:50am

Hi all,

I’m facing an issue when using a parallel multi-instance.

Here is my BPMN:

This BPMN should browse all lines, and for each line browse all commands, and for each command check.

The first test case (working fine):
Json Input :

{
	"id": "1",
	"name": "Facture 1",
	"state": "Ok",
	"lignes": [
		{

			"commandes": [

The second test case (not working):

Thanks for your help.

Hi @m.issoulghane

The output variable in the attached model includes a JSON that differs from the one in your post. It contains only 9 items where state != "Ok".

Hi @hassang

Thanks for the quick reply.
Indeed, to reproduce the issue, you can replace the output variable in the first BPMN or use this one instead.

loop10lignes.bpmn (19.1 KB)

Hi @m.issoulghane

If I am not mistaken it looks like a bug. I am using the 8.5 self-managed version.
Through my experiments, I’ve discovered that the issue arises when using exclusive or inclusive gateways. However, if no gateways or parallel gateways are used, everything works as expected (all outer and inner items are processed).
