Use cached birt reports in custom dashboard [message #1050922]

Hi,

i have made my own custom dashboard (with jsp) and with WebViewerExample.

On the dashboard i show different birt reports (charts) within different iframes. I cache the reports (by using frameset servlet and rptdocument), as they dont change for around 24 hours.

This is what i do:

1-call the frameset servlet with __document param to create the rptdocument:
frameset?

__toolbar=false&__navigationbar=false&__document=myreport1.rptdocument&__report=myreport1.rptdesign

2-whenever my dashboard is called the report is now cached from myreport1.rptdocument

But what i have experienced is that the frameset-servlet is very slow (uses 3-6 seconds to show the result).
If i use the preview-servlet with the __document parameter it shows it under a second. A lot quicker.

This is what i want:

1-check if rptdocument for dashboard-report does exist.

1.1 if rptdocument not exists call frameset servlet:

frameset__toolbar=false&__navigationbar=false&__document=myreport1.rptdocument&__report=myreport1.rptdesign

1.2 if rptdocument exists call preview servlet:

preview?__document=myreport1.rptdocument

But the problem is that the preview-servlet does not generate a rptdocument, it can only show a report. Is there a smart way that i in my dashboard
check if a rptdocument exists, if not call the frameset servlet to generete the rptdocument. And the next time always call the preview-servlet ?
