Get Information of a UserTask which is not created yet.

When my process is in a UserTask A, i need to get Information (form properties, and assignment expressions) of a UserTask B which is not crated (reached) yet (I have processDefinitionId and userTaskDefinitionKey of B). No expression evaluation is necessary.Is it possible? how?Thanks in advance

I am afraid that this is not possible through the current API. However, its possible by using internal implementation classes (which may change in the future)

[java]
ProcessDefinitionEntity processDefinitionEntity = (ProcessDefinitionEntity) repositoryService.getProcessDefinition(processDefinitionId);
TaskDefinition taskDefinition = processDefinitionEntity.getTaskDefinitions().get(userTaskDefinitionKey);
[/java]

Check ProcessDefinitionEntity class

Thanks for quick response,

How can i get form-properties (TaskFormData) from a TaskDefinition? It has a TaskFormHandler field which needs TaskEntity for creating TaskFormData.

<code>
public interface TaskFormHandler extends FormHandler {

TaskFormData createTaskForm(TaskEntity task);

Expression getFormKey();
}
</code>

Try using the UserTask BPMN model which you can get as follows:

[java]
UserTask userTask = (UserTask) repository.getBpmnModel(processDefinitionId).getFlowElement(userTaskDefinitionKey);
[/java]
