Form event handler not being called

[Toby Hobson]

Can anyone see anything which is wrong with this code:

EditPhoto.tml:

<t:form t:id="editPhoto">
  <t:textfield value="photo.name" />
  <input type="submit" />
</t:form>

EditPhoto.java

public void onSubmitFromEditPhoto() {
  ...
}

my event handler is not being called, I have also tried

@OnEvent(value="submit", component="editPhoto")
public void update() {
 ...
}

but this doesn't work either :(

Thanks

Toby
