Hello Davor, What is the best solution from your point of view ? As there is many options in Tapestry 5 framework, i'm not always sure of the one I choose to do something.
Service Alias is a really powerful feature to replace an existing service implementation, Decoration can be used as well but from my Point of view, the principle of decoration is near to the "aspect" concept and may be more suitable to implement general behaviour like logging. Thanks in advance for your answer, Christophe. -----Message d'origine----- De : Davor Hrg [mailto:[EMAIL PROTECTED] Envoyé : mardi 10 juin 2008 13:15 À : Tapestry development Objet : Re: [T5] overriding application-wide message catalog location? to change a service you can also use service decorators, http://tapestry.apache.org/tapestry5/tapestry-ioc/decorator.html and for config just add a SymbolSource http://tapestry.apache.org/tapestry5/tapestry-ioc/symbols.html Davor Hrg On Tue, Jun 10, 2008 at 12:33 PM, Cordenier Christophe < [EMAIL PROTECTED]> wrote: > Hello > > Take a look at the service 'Alias'. > > There is also a thread about this : > http://markmail.org/search/?q=tapestry+type%3Ausers+list%3Aorg.apache.tapestry.users+Can+you+try+with+something+like+this%2C+Override+and+alias#query:tapestry%20type%3Ausers%20list%3Aorg.apache.tapestry.users%20Can%20you%20try%20with%20something%20like%20this%2C%20Override%20and%20alias+page:1+mid:bd4xfcmup7cdlbes+state:results > > Christophe. > > -----Message d'origine----- > De : news [mailto:[EMAIL PROTECTED] De la part de Neeme Praks > Envoyé : mardi 10 juin 2008 10:45 > À : [email protected] > Objet : [T5] overriding application-wide message catalog location? > > Hi all, > > Tapestry5 is shaping up quite nicely, great work! > As a result, I have chosen Tapestry 5 as the framework to build a new > project on :-) > > Inevitably, there will be questions and here is mine: > Is there some way to override application-wide message catalog > location?
