please read exception message. answer straight in there.
javax.el.propertynotwritableexception: /index.xhtml @29,118 value="": illegal syntax set operation
at line 29, character 118 of /index.xhtml you've value="". not valid syntax el value expression should writable through setter method.
normally, specify value attribute value="#{bean.property}" wherein bean has getproperty() , setproperty() method conform javabeans specification.
it's one:
<h:inputtext styleclass="form-login" title="username" value="" size="30" maxlength="2048" /> i'm not sure why specified value that. plain wrong. should either remove altogether
<h:inputtext styleclass="form-login" title="username" size="30" maxlength="2048" /> or bind valid bean property
<h:inputtext styleclass="form-login" title="username" value="#{somebean.username}" size="30" maxlength="2048" /> please note problem has nothing changing jsf locale.
unrelated concrete problem, nesting forms illegal in html , therefore in jsf. should split language selection , user login on 2 separate forms. don't want submit login data when change language. further, may find hints in answer helpful how change jsf locale: localization in jsf, how remember selected locale per session instead of per request/view
