[news.eclipse.birt] Re: How to remove report caching for Report Viewer

["Robert I. Lin" <Robert.Lin@xxxxxxxxxxxx>]

Hey Jason,

it turns out the cause of this problem is that I have a war file that is 
never unpacked, and in the method ViewerAttributeBean.processReport(), 
there's a line
if ( lastModifiedOfDesign != -1L)

which checks the modified date of the rptdesign file, unfortunately in this 
case, this will always return false because the design file is not a valid 
file system file, it's packed inside the war file, so whatever is in that if 
statement never gets executed, which means the rptdocument file is never 
removed, and later on after the soap call to the BirtViewerReportService, a 
re-execution of the report is called only if the rptdocument is not present, 
so in this case, a re-execution of the report is never made.

Sorry that's a very messy explanation, hope you understand what I just typed

Anyway, shall I still log a bug?
