found a workaround for this
seems like the Assignments field in the Reusable Subprocess need to be assigned like this:
item->varMap
instead of
varMap=item or varMap=#
{item}
but the problem is assigning value like this is not always possible if we use the assignment dialog (by clicking on the dropdown field's down arrow) because the first column "From Object" validate the input, if we write something that is not available in the dropdown list of the "From Object" then it will be cleared.

The only way to do this now is to write directly to the Assignments field in the property panel

Description

I have two Processes:
1. test.SimpleApproval
2. test.testMultipleInstance

in test.testMultipleInstance, I have a Multiple Instance Node, inside the Multiple Instance Node, I have a Reusable Sub Process that invoke test.SimpleApproval

The Problem is I can't pass in input variable to the Reusable sub process.

the error is

Could not find variable scope for variable _AC2D2281-2882-4B44-BCED-62D5DBF6C2C4_varMapInput

where varMap is the name for input variable in Reusable Sub Process..

what could have gone wrong?

Then I try to simplify my process to just start - reusable Sub Process - end

and i got the same error in the log

Could not find variable scope for variable _E55BD645-C28C-4394-98D6-906EF811F97F_pvData1Input

What may be the cause?

Is it an issue with the Web Designer?

I attach the process definition and error log

Note:
1. I Use JBPM 5.4 Final fron JBPM5.4 Final Full Installer
2. I Use the Web Designer that comes with JBPM5.4 Final Full Installer to create the process definition
