rich:modalPanel loading the data when opened

[anonyin]

I have several rich:modalPanels which will be launched from a single(parent) page. As I have included all the modalPanels in the parent page. Everytime the parent page is loaded all the modal panels included along with their data(comboboxes) are also getting loaded.

I want the content of the ModalPanel to be loaded only when it is actually opened, so that when the parent page is loaded included modalPanels data is not loaded.  Is there anyway to acheive this.

Thanks

Also I have a modalPanel(Level 2) ontop of a modalPanel(Level 1) and I need to pass the value selected from a dropdown in Level 1 modalPanel  to the Level 2 modalPanel. This passed value is used to filter the data in the Level 2 modalPanel dropdown data.

With my current implementation all the dropdowns data(Parent page, Level 1 modalPanel and Level 2 modalPanel) is getting loaded when the parent page is loaded.

Please advise how I could acheive this.

Thanks.
