I think theres some knot in my head I just can not figure out a solution for the following problem:
I would like to use a BeanItemContainer and a Form to display and edit information of a Song like shown in the attached simple_edit_song.png.
When the user selects an artist in combobox “Artist” I want to show only records of this artist in the combobox “Record”.
I do know how to achive that behavior without a Form and a BeanItemContainer but i was wondering if there is a way to use them.
I do not have any code for this because I need a solution for that problem in a larger more complex project and thought that it might be less confusing with this simple example.
Which Vaadin version would you like to use (7 or 6)? If 6 you can look a bit into my simple application where I had faced with problems like complex form with tabs and validation, application working on few tabs in browser without session connection problem, CRUD with SQLContainer, global variables to each session and few more things.
In Vaadin 6 you could use a custom FieldFactory on a form, and filter the second Select component on ValueChange in the first. In Vaadin7, you can do the same thig, but without the FieldFactory (create the fields yourself).
thank you for your help. I am using vaadin 6 and I have achieved my goal using the
customfield addon because it allows me to use a FieldFactory to put a new custom made field instead of the “record” property into the Form.
