RE: How to use a form itemdatasource to hold table data

Vaadin 6 / 7 / 8 Framework Data Binding

Your data bean should never include Vaadin components; just store the selected value(s) in the original data format (bean class). Then use BeanItemContainers in your table that you populate yourself; Create The Table, fetch all possible selection values, create the BeanItemContainer from them, and set that container to the table. The form should then be able to set/get the values correctly.

I completely agree. I’d actually started out with a Collection<Object> and thats because if u look at the table, I’m using addContainerProperty

                hurdles.addContainerProperty("Hurdle", String.class, null);
                hurdles.setColumnWidth("Hurdle", 310);
                hurdles.addContainerProperty("Choice", ComboBox.class, null);
                hurdles.setColumnWidth("Choice", 100);
                hurdles.addContainerProperty("Comment", TextField.class, null);

then add a row with

hurdles.addItem(new Object[]{
                            "Is there a market for the products of the business?", choice, new TextField()}, 1);

So my expectation was that my bean would be populated with Collection<Object>.

that didnt work though.

Yep I appreciate that, but my question is how…trust me I’ve tried so an example would be very helpful

Guys.

Pretty please I need this. I’ve already done a workaround but the code is not clean at all, so if you could help I would really appreciate it.
