[Chameleon] scalebar widget/ print friendly page/session

[Julien-Samuel Lacroix]

Hi,
Did you try to set the scalebar color in your main page?

 From what I've seen of this discussion and understood of your problem, 
you could simply set the scalebar color in your index.phtml page. 
Instead of reopening the session in your PrinterFriendly page and reset 
the scalebar, simply set the color in the main page between the 
CWCInitialise and the CWCExecute:

$oApp->CWCInitialise();
$oApp->moMapSession->oMap->scalebar->label->color->setRGB(255,255,255);
$oApp->CWCExecute();

This way the scalebar will always have the same color in the main page.
