How to use FormsGraph in my forms

Question

Hello everybody,
I want to use FormsGraph in my forms. Demo works fine but when I create a bean area in my form, bean area is empty and get some error messages in the java console (1.3.1.13):

Hi,
hard to tell because the error simply says that there is a class missing that is expected. If you are not using other beans in Forms, can you take out the Graph bean to see if your module runs without? If it does, then we know that the problem is related to the bean. If the Forms module still doesn't run then you would have to take out the next bean until eventually the error goes away. Starting from here you put think back in and see when th eproblem reoccurs. This helps you to narrow down the problem.
