2.Make sure the Process Explorer pane does not contain any Intalio|BPMS Business Process Project with same name.

Steps to remake process:

1. Go to File > New > select “Intalio|BPMS Process Project”.

2. Provide Project name as “Loopingsubprocess_until”, click on Finish.

3. Right click on project and go to New > select “Business Process Diagram".

4. Provide diagram name as "Loopingsubprocess_until" and click on Finish.

5. A pool with a task is available on the modeler window. Name the default pool as 'Client' and default task as 'send'.

6. Right click on client pool and select "Set pool non executable".

7. Add new pool by click on BPMN Editor (select "Add Pool" option from pop up menu) and name it as "Loopingsubprocess_until”.

Defining outging Mapping:

1. Make sure Mapper view is visible(go to Windows > Show View > Mapper.)

2. In the process model select "sub-one" subprocess.

3. Change the loop type as "Repeat Until" in the properties window.

4. Go to Window> Show View->Palette and select it.
   Note: Drag the Mapper Palette to other location from where you can easily dnd any operator onto the Mapper.

5. Go to Mapper Palette and expand "Functions and Operators on Numerics” Comparison of Numeric Values" and dnd "op:numeric-greater-than" operator onto the Mapper Area.

6. Click on "creates a new operator" button available in Mapper tool bar.

7. A text box will be available in edit mode, provide "10" in the text box without double quotes.

8. Click on "$thisReceiveRequestMsg:body" node in left side of Mapper area and then click on the left edge of the textbox displaying ">" .

9. Click on right edge of textbox displaying numeric value "10" and then click on left edge of textbox displaying ">" operator.

10. Click on right edge of textbox displaying ">" operator and then click on "repeat until" node given in right side of Mapper area.

11. Select "loop" task in the modeler and go to Mapper.

12. Go to Mapper Palette and expand "Functions and Operators on Numerics Operators on Numeric Values" and dnd "op:numeric-add" operator onto the Mapper Area.

13. Click on "creates a new operator" button available available in Mapper tool bar.

16. Click on right edge of textbox displaying numeric value "1" and then click on left edge of textbox displaying "+".

17. Click on right edge of textbox displaying "+" operator and then click on "$thisReceiveRequestMsg:body" node given in right side of Mapper area.

18. Select “reply” task in the modeler and go to Mapper.

19. Click on "$thisReceiveRequestMsg:body" node in left side of Mapper area and then click on "$thisReceiveResponseMsg:body" node given in right side of Mapper area.

20. Save the process design.

21. Now your process is fully implemented which is ready to deploy and execute with in Intalio|BPMS server.
    

Process Deployment & Execution:

1. Click on Deploy Project to Intalio|BPMS Server button in tool bar.

2. Make sure you select all runtime files while exporting to Intalio|BPMS Server.

3. Click on Finish button.

4. Open a web browser, provide url as: http://localhost:8080/bpms-console which takes to login screen for bpms-console.

5. Login with the following credentials:
   username: 'admin' (without quotes).
   password: 'changeit' (without quotes).

6. Bpms-console will be available with deployed processes list.

7. You should see "Loopingsubprocess_until:Loopsubprocess_until" process with a package name "Loopsubprocess_until", select it and click on Start.

8. This should generate a form with an input filed.

9. Type '1' in loop field, then click on Submit button.
