flowRequestContext not available in error.vm

[Dominique Petitpierre]

Hi Christopher,

here is how we added locale choice in all the user views, including error.vm:


#if ($request.getQueryString())
    #set ($querynolang = $request.getQueryString().replaceAll("&?lang=[a-zAZ_]+",""))
#else
    #set ($querynolang = "")
#end
#set ($lang = $springMacroRequestContext.getLocale().getLanguage())

<div class="lang">
#if ($lang.matches(".*[Ff][Rr].*"))
FR | <a href="?$querynolang&lang=en">EN</a>
#else
<a href="?$querynolang&lang=fr">FR</a> | EN
#end
</div>


Not very general, but good enough for us.

$lang is initially set to the browser's locale preference (no default set in the localeResolver bean), then it is set to the flow's locale ("stateful" while the flow lasts).

Let us know if you implement a different solution!
