problem regarding parameter length in drill through report [message #1409785]

Hi everyone,
I am facing a parameter length problem when creating a hyperlink to drill through from one report to another report. If the the length of parameter is less than 1000 characters, the detail report works fine, but sometime the parameter is more than 1000 characters, when redirecting to the detail report, it only display a blank page without anything.

My BIRT version is 2.6.2

Appreciate your help in advance.

You could create your own link in a HTML text box and use a POST form like this:

<form method="POST" target="Birt" action="http://127.0.0.1:59668/viewer/frameset"
accept-charset="utf-8">
    <input type="hidden" name="__report"
value="C:/Users/mwilliams/workspace/BIRT 4_4_0/BIRT 4_4_0/longparamPOST.rptdesign">
     <input type="hidden" name="__format" value="html">
     <input type="hidden" name="LongParam" value="START long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text long text END">
   <button type="submit">Drill Through</button>
 </form>

My guess is with the long parameter through the URL is that you're hitting a character limit. Hope this helps.
