This is not an error. This is a warning. The code looks fine, all input components are inside a form, it seems that it should run and work fine. If it indeed works fine, just ignore the warning. This warning is displayed only when the context parameter javax.faces.PROJECT_STAGE is set to Development anyway .

As to the false warning message itself, this check was introduced in Mojarra 2.1.1 as per issue 1663. However, as per issue 2147 it turns out to have some bugs and is been further improved in Mojarra 2.1.3. I'd imagine that the false warning is in your particular case caused by having an <ice:panelLayout> between the form and the input elements.

If you aren't on Mojarra 2.1.3 yet, you may want to consider upgrading to see if it removes the false warning message.
