The issue seems to be your assignment mapping of the task data outputs.
Please note the "To" and "From" columns in the data assignments
editor:
** When you are mapping DATA INPUTS:
"From" columns should have the object you are mapping from, so like
process variables, globals, etc
"To" columns should have the object you are mapping to, so the data
input of your task
** When you are mapping DATA OUTPUTS:
"From" columns should have the object you are mapping from, so your data
output of your Task
"To" columns should have the object you are mapping to, so like your
process variables, globals, etc.
I think in your case you should just switch your assignments for your
task data outputs, so:
** Task 1:
from Object="Approve" is mapped to "ApprovedRequest"
should be
from Object="ApprovedRequest" is mapped to "Approve"
** Task 2:
from Object="Order" is mapped to "OrderItem"
should be
from Object="OrderItem" is mapped to "Order"
Hope this helps.

Thanks a lot for reply,
Actually I was searching the internet and I found your post in
wordpress. And yes it was a variable or binding error. I removed all
the variables and the forms generated with the no data.
So, Could you please give me some hints about the variables in Drools.
My whole process example is composed of 2 user tasks only:
* In the process properties under "*Variable Definition*", I add
"ItemID" = Integer and "ItemName" = String and
"Approve"=Boolean
and "Order"=Boolean
* In the first task properties: under "*DataInputSet*", I add
"AddItemID"=Integer and "AddItemName"=String | Under
"*DataOutputSet"* I add "ApproveRequest"=Boolean
o Under assignments, From Object= "ItemID" is mapped to
"AddItemID", From Object="ItemName" is mapped to
"AddItemName", from Object="Approve" is mapped to
"ApprovedRequest"
* In the second task properties: under*"DataInputSet"*, I add
"OrderItemID"=Integet and "OrderItemName"=String | Inder
*"DataOutputSet"* I add "OrderItem"=Boolean
o Under assignments, From Object= "ItemID" is mapped to
"OrderItemID", From Object="ItemName" is mapped to
"OrderItemName", from Object="Order" is mapped to
"OrderItem"
Thanks,

Task Form generation parses your process BPMN2 and it looks as you
have
some issues with it - click on the "BPMN2" button in the Designer
footer
and then either provide the BPMN2 shown, or the server log error(s) it
generates. If you get errors, provide those, and also click on the
"JSON" button in the footer and provide the JSON representation of
your
process.
You can click on the "info" button in the Designer header to
provide the
Designer version you are using...that will help as well
Thanks.
