hi, I just had to deal with this myself. The function seems to have been disabled in the core script files. You may try re-enabling it again until a permanent fix is available. Add the following script block in your page (preferably the masterpage)
<script type="text/javascript">
function pageLoad()
{
if (__wpm != null)
{
if (!__wpm.ExportWebPart)
__wpm.ExportWebPart = WebPartManager_ExportWebPart2;
}
}
function WebPartManager_ExportWebPart2(exportUrl, warn, confirmOnly) {
if (warn == true && __wpmExportWarning.length > 0 && this.personalizationScopeShared != true) {
if (confirm(__wpmExportWarning) == false) {
return false;
}
}
if (confirmOnly == false) {
window.location = exportUrl;
}
return true;
}
</script>
Also note that I have taken the liberty to change the original function name from
WebPartManager_ExportWebPart to WebPartManager_ExportWebPart2 ; this is done on purpose in case ms decided to fix this in a future release, you won't go into conflict and it should just work whether you remember to remove the above workaround or not.
Have a good day,
