How do I enable and disable a modalPanel from javacode?

[xterm2]

Beeing new to richfaces this is what I want to acomplish

I want to use a modalPanel to display a "please wait" dialouge to the user while I perform a heavy db question. I have a form on a page with a dropdown field. Thisa is connected to a datafield that displays data from a database. It takes a while to get the value from database and I want to display a "please wait" dialouge during this time.

I Like how the modalPanel lookes and wnat to use it but how do I enable/disable it from javacode?

What's the simplest way to go? Should I create it dynamicaly or can I connect it from the page to a backingbean?

Any ideas?

If you wanna attach this wait box only to some buttons which performs the huge db calls - just point this statuses directly from buttons as described in our guide.

Looks great. But I'm not shure on how to enable/disable it. When I change the value in the dropdown field, this is connected to a backingbean that do some db stuff and to a <a4j:support event="onchange" reRender="datafield"> thing. How do I enable/disable the modalPanel?

I just don't get it

Sorry...
