Re: [Wicket-user] IMG reload via AJAX
there are a couple of ways:one) add anti caching headers to your resourcetwo) append a random number to the resource url-IgorOn 4/7/06, Jerry Smith [EMAIL PROTECTED] wrote: Hi all, I'm trying to get an Image to reload via AJAX.

Ive already got res.setHeader(Cache-Control, no-cache); res.setHeader(Cache-Control, no-store); in the resource, how do I go about changing the src url?

Re: [Wicket-user] IMG reload via AJAX
what are you using right now to display images?usually i call urlfor(resourcereference), get the url, append rand=+Math.random() and use an attributemodifier or oncomponenttag() to set the src attr of an img tag. -IgorOn 4/7/06, Jerry Smith [EMAIL PROTECTED] wrote: I've already got res.setHeader(Cache-Control, no-cache); res.setHeader(Cache-Control, no-store); in the resource, how do I go about changing the src url?

url=url+rand=+UUID.random().toString() but wait...even with that there is a chance of collission...hmmm Is there? Isn't UUID supposed to be unique in space and time?
