get Expression

[arag]

Hello!!!

Well i have a question, and I don´t know if it is posible...

I have a bpmn with many form properties, all of them have a Expression, and i need to recover this information

is there some method or a way to do that??

Thanks for your time

I'm sorry. I did not understand what you really wanted to do.
Do you want to get a list of form properties?

I need to obtain "Expression"

Thank you for your reply.
If you use Activiti6, you can get expressions of form property by using internal api, like this code.

If you use Activiti 5.22, please tell me.

// Start form
org.activiti.bpmn.model.Process process = ProcessDefinitionUtil.getProcess({ProcessDefinitionId});
StartEvent startEvent = (StartEvent) process.getInitialFlowElement();
List<org.activiti.bpmn.model.FormProperty> formProps = startEvent.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}

// Task form
UserTask userTask = (UserTask) process.getFlowElement({ActivityId}, true);
formProps = userTask.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}

Thanks to you, specially for you time... I'm using activiti 5.22

I'm sorry that the following code works with both versions.

BpmnModel bpmnModel = repositoryService.getBpmnModel(processDefition.getId());

// Start form
StartEvent startEvent = (StartEvent) bpmnModel.getFlowElement("startevent1");
List<org.activiti.bpmn.model.FormProperty> formProps = startEvent.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}

// Task form
UserTask userTask = (UserTask) bpmnModel.getFlowElement("usertask1");
formProps = userTask.getFormProperties();
for(FormProperty prop : formProps){
    System.out.println(prop.getExpression());
}
