Hi,

I am currently working with MyFaces and am having a nightmare with the java.lang.IllegalStateException: Client-id : xxx is duplicated in the faces tree.

My page works fine until I use a h:selectBooleanCheckbox with onchange="this.form.submit()", now when I click the boolean checkbox and the page gets re-posted I get the above exception.

I cannot find any reason for why this is happening and my googling hasnt come up with much either, any ideas would be really appreciated.

thanks,

John

Does the error occur when you don't click the checkbox?
