Hi All,
Iam new to jbpm web based designer for BPMN modelling. And I have few questions:
- Is it possible to customize the designer in a way that allows only custom tasks/service nodes (just examples...could be other BPMN constructs as well) to be available/visible to business users? In general I want the business user to see only pre-defined process constructs that are available for use (and not the world!).
- Is it possible to introduce custom validations such that if the business user constructs process model that is not valid or possible in a particular business case (even though it may be a valid BPMN 2.0 model), then a error can be shown (similar to red X for invalid BPMN)? As example, there may be pre and post conditions on some service nodes that needs to be satisfied before a valid link can be established with other nodes. And such pre and post conditions can be based on input/output data or rule based. 

So please advice if these things are possible out-of-box with the current designer or what is the best away to approach such need?
