Money Task example, ActivitiUiUtil id error

[mark1]

Hi

I'm new to Activiti and was trying out a couple of examples in the users guide.

I did successfully  create a simple workflow process using the Activiti Designer Eclipse plug-in and deployed it to the Activiti Explorer application.

When I tried to do the Money Task example I had a problem.

My current environment:

Activiti 5.11.1
Eclipse Juno
Activiti Designer Eclipse plug-in 5.11.1
    but in the POM it seems I have to specify 5.9.1


My Money Task compiles, and I can load it into a different Eclipse work space to try to use. The new Money Task shows up in the palette but when I try to add the task to a workflow it get errors. I can't actually add any tasks, because I always get the same error now.

Hi,

I think you are using the wrong version of the integration JAR.
The money task example is updated in Github, you can take a look at that:

https://github.com/Activiti/Activiti-Designer/tree/master/examples/money-tasks

Best regards,

hi thx,
was same error by me, i download the right jar from git and it works.( or just change version of your actual money task in your pom to 5.11.1).

Hi thx as well,

This worked for me as well. Once I removed my old test project and started over with a new Activiti project the money task is working fine.

Thanks again
