Script with 'location.href=' doesn't work on a chart

Baku

Hello all,

I try to do something simple :
On a chart, when the user clic on a serie, it calls a script (invokeScript).
In this script I have a location.href = 'someurl'.

This works perfectly when I load the Report on a Web Browser, but the redirection doesn't work when I load the report with the viewer integrated in Eclipse. And I need it to work with this viewer (we are using an java application with the reports directly integrated).

If I try to call this function from another component (submit button,...) it works too. It fails only with a chart. I know my url is good cause I put an alert(url); before the location.href...

Any ideas with this ?
Thx in advance.
