Hi,

There seems to be an issue with multiple validation summaries with a validation summary on each UltraWebTab. It seems on page load the script is trying to remove other validation summaries not on the current tab, even though the LoadOnDemand async option is set on the tabs.

On page load, a script error is thrown (as null) on the dispose function shown below.

document.getElementById('ValidationSummaryClientId).dispose = function() {
    Array.remove(Page_ValidationSummaries, document.getElementById('ValidationSummaryClientId'));
}

But when I remove the ValidationSummary, it seems to work fine. The error seems to appear only once on the initial page load though.

When I set the LoadOnDemand, why is it trying to remove the Validation summaries on other tabs?

Also for testing, when I put a alert on each tab, the previous tab alert is shown and then the current tab. If it might help, I the following level:

Master / Page / UltraWebTabControl / UserControl (UserControls have validation summaries)

Thanks
