Hi Juergen,=0D=0A=0D=0AOk, as I have a way to retrieve the current theme =
in the view, I'm happy.=0D=0A=0D=0ANevertheless, as Rod sayed one day tha=
t the view definition file will have to be reviewed, adding a 'parent' pr=
operty could be useful for avoiding repetitive properties.=0D=0A=0D=0AReg=

oper] Theme issue=0D=0A=0D=0AHi JP,=0D=0A=0D=0AI can see what you were ai=
ming at. But unfortunately you've misunderstood the purpose of the Cookie=
ThemeResolver's request attribute: It is only there to override the cooki=
e value if changed in the course of the current request, to avoid reading=
 the stale value from the cookie in the request object. It was never mean=
t to be used by application developers, not in controllers and not in vie=
ws. The attribute name contained the full CookieThemeResolver class name =
on purpose, as it is just an implementation detail.=0D=0A=0D=0AThe proper=
 way to retrieve the name of the current theme is RequestContext.getTheme=
(), as used by ThemeTag underneath the hood. You can instantiate a Reques=
tContext yourself, or instruct the View implementation to add an instance=
 under a specified model attribute name, like as follows:=0D=0A=0D=0A  ex=
ample.class=3Dcom.interface21.web.servlet.view.InternalResourceView=0D=0A=
  example.requestContextAttribute=3Drc=0D=0A  example.url=3D/example.jsp=0D=
=0A=0D=0AWith this configuration, a model attribute "rc" of type RequestC=
ontext is available for the view. With JSTL, you can simply access the cu=
rrent theme name via "${rc.theme.name}" then (specifying no scope simply =
searches page -> request -> session -> application).=0D=0A=0D=0AI guess I=
 haven't made RequestContext obvious enough. I'll revert the changes prom=
ptly, and add a respective comment to CookieThemeResolver.=0D=0A=0D=0AReg=

Subject: [Springframework-developer] Theme issue=0D=0A=0D=0A=0D=0AHi Juer=
gen, everybody,=0D=0A=0D=0AI tried to test the current theme and locale i=
n a view for avoiding=0D=0Alinks to current choices. I encountered these =
issues and committed=0D=0Achanges.=0D=0A=0D=0A1) The request attribute co=
ntaining dots forces to use the brackets=0D=0Asyntax, but we can leave wi=
th this.=0D=0A2) The request attribute is a bit long: <c:when=0D=0Atest=3D=
"${requestScope['com.interface21.web.servlet.theme.CookieThemeResol=0D=0A=
ver.THEME'] =3D=3D 'xxx'}">=0D=0A3) The request attribute contains the im=
plementation class name of the=0D=0Aresolver. If we change it in the conf=
iguration, the JSP have to be=0D=0Achanged accordingly :-(. For the point=
 2 and 3, I have changed the=0D=0Arequest attribute name to the fixed Str=
ing 'com.interface21.web.THEME'=0D=0Adefined now in ThemeResolver. I am a=
ware that it breaks the backward=0D=0Acompatibility, but it solves this i=
ssue from this point (I think=0D=0Aespecially on point 3).=0D=0A4) When t=
he theme is set, all is ok. But for next views, the current=0D=0Atheme na=
me is no longer available, so the default is returned. I added a=0D=0Anew=
 method 'makeThemeNameAvailable' in the ThemeResolver called by a new=0D=0A=
else clause in ThemeChangeInterceptor. So, when an interceptor is used,=0D=
=0Athe request attribute is always set.=0D=0A=0D=0ARegards,=0D=0AJean-Pie=
