“Please wait while scripts are loaded…”
Some of Sharepoint developers might be familiar with this kind of message. It appears in the status bar of Internet Explorer when some action is executed. If the message disappears, fine, but what if it remains there and the desired behavior isn’t executed?
I was getting this “Please wait while scripts are loaded” message on a web part page with one particular web part, which had some custom verbs defined. Web part verbs are kind of menu items for a web part, that allow to perform some actions on it. For each verb, one can define server-side and client side action to be performed when the verb / menu item is clicked. And this client side code of the verb was the crux of the matter.
I replaced the string with an underscore and the problem was solved. At this time I thought that maybe the names or ID’s in aren’t allowed to contain characters like hyphen. But no, according to W3C, hyphens are allowed since they’re not the first character of ID or name. Probably Internet Explorer tries to evaluate the expression, treating the hyphen as a minus sign. And reaches a deadlock at some point (please wait while scripts are loaded…)
Hope this helps,
