Hello! last november we added the dynamic legend widget to our viewer, and it's been working with no particular problems, until a few days ago. No changes at all have been performed on any HW/SW configuration since then. Now, when one clicks on the widget icon, the system returns the following error message in the widget window: ---------------- (mx.messaging.messages::ErrorMessage)#0 body = "<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Server</faultcode><faultstring>Server was unable to process request. ---> Object reference not set to an instance of an object.</faultstring><detail /></soap:Fault></soap:Body></soap:Envelope>" clientId = "DirectHTTPChannel0" correlationId = "E4258224-CB77-5E1A-D5FE-76C5BAB1D256" destination = "" extendedData = (null) faultCode = "Server.Error.Request" faultDetail = "Error: [IOErrorEvent type="ioError" bubbles=false cancelable=false eventPhase=2 text="Error #2032"].

The problem therefore seems to be in the phase of building the xml legend file or when this xml file is read and displayed in the widget.
