OnError() function in web service: impossible?

Question

Hi,
Context: A ColdFusion web service with application.cfc and OnError() function.
I want the OnError function to log and email me when exceptions occur in web service but for some reason OnError() is never fired in such a case.
It's weird because it works if a .cfm page is called instead of a .cfc!
Is it a standard behaviour with CF webservice? Is there a workaround?
Thanks

Hi Dan,
Thank you for reading and suggesting. The fact is I would like to use onError() for what it is supposed to provide - and also to understand the mechanism.
My onRequestStart() sets request variables to bar.cfc so application.cfc globally plays fine with the webservice cfcs. Well... except for error handling
I found that if exception occurs in application.cfc it is actually caught by onError().
But if exception occurs in webservice cfcs then it is not caught by onError() and a ugly SOAP error is sent to consumer instead.
Here are my application.cfc and bar.cfc webservice components. They are pretty simple so I don't see why onError() is not fired:
<cfcomponent displayname="Application" output="false">
    <cfscript>
        this.Name                = "foo";
        this.applicationTimeOut    = CreateTimeSpan(0,1,0,0);
        this.sessionManagement    = false;
        this.setClientCookies    = false;
        this.clientManagement    = false;
        this.scriptProtect        = "all";
    </cfscript>
    <cffunction name="onApplicationStart" access="public" output="false">
        <cfset application.foo= "foo" />
    </cffunction>
    <cffunction name="onRequestStart" access="public" output="true">
        <cfargument name="targetPage" type="string" required="true" />
    </cffunction>
    <cffunction name="onError" access="public" returnType="void" output="true">
        <cfargument name="Exception" required="true" />
        <cfargument name="EventName" type="string" required="true" />
        <cfmail from="toto" to="[email protected]" subject="error">
            error
        </cfmail>
    </cffunction>
</cfcomponent>
<cfcomponent displayname="bar">
    <cffunction name="test" access="remote" returntype="cpTest" output="false">
     <!--- Throws an exception as b does not exist. This must be caught by onError() but it is not --->                   
     <cfset a = b />
     </cffunction>
</cfcomponent>
Any clue?
