Disable/Delete Not Existing Validation - jsf

Question

I implement a <h:form> to edit Employee data which gets preloaded from the database. The preload works fine - all fields get filled with data. The <h:form id="editEmployeeForm"> is surrounded by a <h:form> which contains a <p:dataTable>.
When I do an edit on Employee data and click the "Speichern"-button nothing happens. <p:messages> says all my fields are empty what is obviously a wrong validation because all fields are prefilled. Then I deleted all <p:message> tags from my <h:inputText> tags to check whether the doSaveEmployeeEdit() gets called at all. But nothing happens - no error in console, etc. Even a simple System.out.println() doesn't get printed from the doSaveEmployeeEdit() at all.
Below the <p:dialog> what I have at the time:
<h:form id="editEmployeeForm">
<p:dialog header="Angestellten ändern" id="employeeEditDialog" widgetVar="employeeEditDialog" modal="true" showEffect="fade" hideEffect="fade" resizable="false" closeOnEscape="true">
<p:outputPanel id="employeeDataEdit" rendered="#{not empty employeeEditController.employee}">
<h:panelGrid columns="2">
<p:outputLabel for="usernameEdit" value="Benutzername: " />
<p:inputText id="usernameEdit" value="#{employeeEditController.employee.username}" disabled="true" />
</h:panelGrid>
<p:separator/>
<h:panelGrid columns="6">
<p:outputLabel for="firstnameEdit" value="Vorname: " />
<p:inputText id="firstnameEdit" value="#{employeeEditController.employee.firstName}" />
<p:outputLabel for="lastnameEdit" value="Nachname: " />
<p:inputText id="lastnameEdit" value="#{employeeEditController.employee.lastName}" />
<p:outputLabel for="birthdayEdit" value="Geburtsdatum: " />
<p:inputMask mask="99/99/9999" id="birthdayEdit" value="#{employeeEditController.employee.birthday}" />
<p:outputLabel for="locationEdit" value="Wohnort: " />

<p:inputMask id="phonenumberEdit" mask="9?99999999999" slotChar=" " maxlength="12" value="#{employeeEditController.employee.phoneNumber}" />
<p:outputLabel for="emailEdit" value="Email: " />
<p:inputText id="emailEdit" validatorMessage="Ungültiges Email-Format!" value="#{employeeEditController.employee.email}">
<f:validateRegex pattern="^$|^[_A-Za-z0-9-\+]+(\.[_A-Za-z0-9-]+)*#[A-Za-z0-9-]+(\.[A-Za-z0-9]+)*(\.[A-Za-z]{2,})$" />
</p:inputText>
</h:panelGrid>
<p:separator/>
<h:panelGrid columns="6">
<p:outputLabel for="familyStatus" value="Familienstatus: " />
<p:selectOneMenu id="familyStatus" value="#{employeeEditController.employee.familyStatus}" style="width:150px">
<f:selectItem itemLabel="Wähle Familienstatus" itemValue="#{employeeEditController.employee.familyStatus}" />
<f:selectItems value="#{enumController.familyStatus}" />

<p:outputLabel for="Religion" value="Religion: " />
<p:selectOneMenu id="Religion" value="#{employeeEditController.employee.religion}" style="width:150px">

<f:selectItem itemLabel="Wähle Arbeitsrolle" itemValue="#{employeeEditController.employee.workRole}" />
<f:selectItems value="#{enumController.workRoles}" />
</p:selectOneMenu>
</h:panelGrid>
<p:separator/>
<h:panelGrid columns="3">
<p:commandButton value="Speichern" action="#{employeeEditController.doSaveEmployeeEdit()}" />
<p:commandButton value="Neu laden" action="#{employeeEditController.doReloadEmployee()}" />
<p:commandButton value="Abbruch" onclick="PF('employeeEditDialog').hide()" />
</h:panelGrid>
</p:outputPanel>
</p:dialog>
</h:form>
What can be the reason that html or whatever still do the validation and don't call the doSaveEmployeeEdit()?
UPDATE:
I made a new xhtml-file with same outputs - no validation anymore. But my controller method doesn't get called.
