performance poor in internet explorer 7 related to input controls

[terco]

Hello,

 

I have a report which has 9 Input controls, 7 from them are cascaded.
This report is running with acceptable performance when JasperReports Server CP 4.0 is accessed with Firefox (3.5 or 5) or Chrome.

With IE 7 it is very slow, the mouse moves slow and the cascading IC react very slow: script loading the ICs?.
After a while, I get the error message:
"A script on this page is causing Internet Explorer to run slowly".

Is it possible to get a better performance via configuration? Ideally in JR-Server since I have no direct access to the users' PCs.

BTW: in my PC I add the registry entry as described in
http://support.microsoft.com/kb/175500/en-us
and this entry, eliminate the error message which pops up after a while "... causing IE to run slowly" but the performance stays equally bad.

Thanks in advance for any ideas.

Hey terco,

I'm having the exact same problem with the slow performance in IE7.  I have spoken with a JasperSoft representative and they seem to know about the issue.  I'm hoping they will look into this at some point in the near future as it's driving me crazy.

Same problem in internet explorer 8. Users cannot enter an input value. Makes the app unusable.

Seems to be list size related. My problems are occuring with large multi-select query input selections. Single-select queries work fine. Small mult-select queries also perform ok. But Large multi-select queries have problems. One with around 8,000 entries starts to have problems and one with 23,000 entries does not work. Both performed well under JasperServer 3.71.

No better with Jasperreports Server 4.2.1.

Have you been able to find a resolution to this problem?  We are now experiencing great latency when using large multi-select List of Values

iReports 4.5.0
