The best way would be to implement your own custom form type. Will you be using the Activiti Explorer or a custom application?

Best regards,

When you use a form to fill in properties, the values are set on the process as a variable. When you use the same form property again, the value that is already present is overridden. You should build some logic (e.g.. service-task, script-task or task-listener) that copies the filled in values to another data-structure (eg. create POJO's passed on that and add it to a list that is stored as process-variable).

I'm a beginner and this explanation made me clear how to find the solution ,I will learn more about POJO;
if possible please send me a simple example to better understand
thank you very much

Check the docs or our unit tests, or just try to put a pojo in the variables

I found an example in org.activiti.examples.bpmn.expression ;which include a Simple POJO, just for test purposes, I run the unit test and it's ok : no error, but when I deploy the process in activiti explorer a warning message appears : Unknown property used in expression: ${order.price<=250}
how can I solve this problem ? thanks

When starting a process in explorer, there are no "start variables" passed. IN the unit-test, the POJO is created and set as variable "order" in the process. The gateway than evaluates the expression. In case of explorer, no "order" variable is present and you get the error.

A solution would be to use an execution-listener (or service-task with java-delegate) that sets the initial value (the POJO) for the "order" property, as first step of the process. This will work in all environments…
