JSF 2 - Ajax - Form not completely rendered -

my ajax codes rendering form using newly-selected locale are:

<h:selectonemenu id="selectlang" immediate="true" value="#{langlisting.language}">    <f:ajax listener="#{langlisting.changelocale}" render="@form" />    <f:selectitems value="#{langlisting.languages}" /> </h:selectonemenu> 

however, since above codes in in header file called header.xhtml, above codes render content of header.xhtml when switch locales between english , french. index.xhtml structure follow:

header.xhtml menu.xhtml body content id of "contentsection" footer.xhtml 

how can render menu.xhtml, body section , footer.xhtml @ same time render header.xhtml?

the @form affects content of parent <h:form> only. use @all instead.

<f:ajax listener="#{langlisting.changelocale}" render="@all" /> 

see description of render attribute in <f:ajax> tag documentation.

however, since changing locale affects entire page anyway, consider fire synchronous request instead of ajaxical one. achieve this, remove <f:ajax> tag, add onchange="submit()" dropdown , move code inside changelocale() setlanguage() method. see this answer concrete example.
