Using Dojox/form/Fileinput give error : 2 elements found with non-unique id

I am using the Dojox/form/Fileinput in a page.
In the console of chrome i find the following error
[DOM] found 2 elements with non-unique id

But the page works fine. How to remove the error from the console.

Hi cavimals,

I can not reproduce the problem…
Could you provide more information about your context, please?

Maybe using some code…
