Re: invoke ECMAScript-Function

Hello Thomas,

thanks for the hint.
But how do I lay my hands on the  BridgeContext? Or may I
not use
JSVGCanvas or JSVGComponent if I intend to use the Bridge?
All fields
and methods that seem helpful to access the BridgeContext I
found
protected (as createBridgeContext, userAgent or
documentLoader).
Is there another way?
TIA,

     Robert

   Get it from the UpdateManager.
