Re: Updating image inside zone
No, I think I solved the problem by adding fake context to the chart component. I think the problem was that browser cached the image with src="someurl" (because the chart is ultimately just an html img. By adding "random" data (our context) to the url we prevent the image from caching (this is my guess). -- View this message in context: http://tapestry.1045711.n5.nabble.com/Updating-image-inside-zone-tp5716498p5716503.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
Re: Updating image inside zone
Maybe your component jfreechart:jpegchart caches the datas.

As I said, I see that zone is updated (there are also log entries for
dao.loadSomeData() every time). but the getChart() method is never called
again and chart content is obviously the same

Re: Updating image inside zone
Can you provide the code when performing zone update? On 26 September 2012 11:50, ch_pasha wrote: > Hi all, > > I have an image with dynamic content inside zone component (jfreechart > actually).

Updating image inside zone
Hi all, I have an image with dynamic content inside zone component (jfreechart actually). Unfortunately when triggering the zone update image content is never updated - getter method returning streamresponse is called only once when the page is first loaded but never again,when zone is updated. Is it an expected behaviour? How can I make the image populate content each time zone is updated? -- View this message in context: http://tapestry.1045711.n5.nabble.com/Updating-image-inside-zone-tp5716498.html Sent from the Tapestry - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org
