Colour palette refresh - WebI

Hi,

I'm using BI 4.0 SP1 and just customised the colour palette by changing VisualizationConfig.template.xml.

The new palette works fine with new WebI reports or new charts within old reports but doesn't come up in the palette list for old charts.

I restarted tomcat after changing the VisualizationConfig.template.xml file. Is there anything I can do to refresh the palette?

Regards,

Matt
