Testing for the presence of jQuery UI modal dialog or alternative on page
I've worked on something similar in the past.
Assuming the modal is contained in a div, I'd start with a 'WaitForVisible' on that to wait until the modal is acutally showing.Then you can interact with the elements in the normal way, and then have a 'WaitForNotVisible' once you've finished with it.
If there isn't a convenient containing div, just pick some other element on the modal to wait for.
The following works with the demo JQuery UI modal dialog at http://jqueryui.com/demos/dialog/

<tr><td>waitForTextPresent</td> <td>Selecione os produtos para impressão</td><td></td>You can use this to check dialog by the title
