Hi there, a code issue:

> Bonita Studio 6.3.7, Java 1.7.0.67, Windows 8.1

I’m trying to delete some processes as details … [click here](http://documentation.bonitasoft.com/javadoc/api/6.3/org/bonitasoft/engine/api/ProcessRuntimeAPI.html#deleteProcessInstances(long)) …

but it’s not working…telling me the system will not process the request as follows:

`

I’m only doing what the Javadoc indicates…

How do I use deleteProcessInstances to delete processes?

My code is as follows:

Code Summary:  
  
In GROOVY

1. prepare and print out existing processes
2. disable the process
3. delete the processes - using a modified while as groovy does not support do{…}while
4. delete the archived processes - using a modified while as groovy does not support do{…}while  

The code:
