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 IE
from displaying content that cannot
// be displayed inline in the browswer (pdf files, for
example). This was a known bug in IE 4.0
// and is reported fixed by MS: http://support.microsoft.com/
support/kb/articles/Q231/2/96.ASP?LN=EN-US&SD=gn&FR=0&qry=Internet%
20Explorer%20cannot%20download&rnk=19&src=DHCS_MSPSS_gn_SRCH&SPR=IE
// "When you try to download a .pdf file from a Web site
that uses the Hypertext Transfer Protocol
// (HTTP) "Cache-Control = 'no-cache'" directive, Internet

// error message: Internet Explorer cannot down load from

setPageRefreshOnBacktrackEnabled(false);
