which components in email

[svande]

Hello forum,
Can someone tell me which rich components can be sent by email?
I get an exception when sending a rich:simpleTogglePanel:

java.lang.NullPointerException
com.sun.facelets.FaceletViewHandler.writeState(FaceletViewHandler.java:776)

But all goes well with a h:panelGrid.
Regards,
Wilfred

In the Seam manual it says:

The <m:body> tag wraps the body of the email. You can use regular HTML tags inside the body
as well as JSF components.
