I found out that this related to the validation. The field of the inputHidden
is not lost.
The code for inputHidden is:
<h:inputHidden id="version" value="#{userForm.user.version}">
This component works correct.
But something like:
<h:outputText value="Version: #{userForm.user.version}" />
wont work as expected
If I submit the form and some other required field is not provided, the
validation fails, then userForm.user.version is NULL for the component
<h:outputText> but <h:inputHidden> is rendered with the correct value
(userForm.user.version != NULL). Eg the HTML sourcecode after failing
validation is something like
<input type="hidden" id="userForm:version" name="userForm:version" value="3" />
Version:
Where I expect it to be:
<input type="hidden" id="userForm:version" name="userForm:version" value="3" />
Version: 3
I guess it has something to do with some other libraries I am using. Any
suggestions where I should start searching? Or could you recommend to replace
all inputHidden with saveState?
Thanks
René

I forgot about the side effects of the disabled property. But the hidden
fields are not disabled and they only get lost when validation errors occur.
If I "replace" inputHidden with saveState it works.
