I vaguely remember running into this. I can't test it (no IE access
at the moment) but my old component has a name bound to the WOImage's
key attribute. I used a random number (eg 123.png) so that the cache
would be refreshed when the image gets updated. Chuck's suggestion
might work too, but if it doesn't, give this a try. If I understand
it correctly, if you don't bind the key attribute then the image has
to be re-fetched each time the page loads, and I guess IE goes back
to the source instead of looking in its cache for printing.
hope that helps, Jacob

Hi list,
I'm using a WOImage to print charts generated by JFreeChart.
This works fine and the generated charts are displayed on the
browsers.
Now when I try to print my page with IE (this works well) the
generated pictures are not printed.
I googled for a while without success, I just found some posts
mentionning cache/content-type issues :
if they are not set correctly IE performs a refresh of the picture
before printing (which is the cause of my problem)
I checked my page for a pragma no-cache in the header and set a
correct mime time in the WOImage bindings without success.
Anyone could help me with this issue ?
Here is one way. This goes in Application.java
// Revert to 4.5 behaviour. Having this enabled prevents

setPageRefreshOnBacktrackEnabled(false);
