Am Really excited to interact with you. I have been exploring Activiti for couple of weeks and I must say, User Guide has been very helpful..
I have a couple of Questions,
1) How do I integrate External forms into the User Task ? The information in User guide is really good, but, can you please give me an example if possible.
2) I have seen some links which tells that the Vaadin is a great combination for Web app and Activiti. Can you please elaborate more on this. I have to confess that I know Java but have never built any web app (before last week, tried Vaadin recently).
1) You can specify a formKey attribute on a userTask that is pointing to your external form/page definition. So if you would for example use JSF, this formKey value could be one of the navigation definitions in our JSF application.
So then you retrieve the formKey value from the user task and let your JSF application handle the navigation based on that value.
The same is true for every other web technology framework of course.
2) We chose Vaadin to implement the Activiti Explorer because we think it's a great web framework. It allows Java programmers to code a web UI with only Java code (and some CSS in most cases).
Because Activiti is also Java based this provides a very good combination.
