PrimeFaces nested form inside p:dialog with appendTo="@(body)

Question

I have this fragment:

Answer 1

Finally, I found a way using OmniFaces, with :

page:

fragment:

This will cause some warning:

WARNING Unable to save dynamic action with clientId 'form:innerForm:dialog' because the UIComponent cannot be found
WARNING Unable to save dynamic action with clientId 'form:innerForm:innerText' because the UIComponent cannot be found
WARNING Unable to save dynamic action with clientId 'form:innerForm:confirmButton' because the UIComponent cannot be found

because the restored components are not re-removed on subsequent RESTORE_VIEW for postback.

These warnings, as for my experiments, are harmless and could be safely ignored.

However I opened a pull request to eventually fix it.
