Standard Messages in WebDynpro - Language Issue

Hi,

I want to know where "standard messages" of webdynpro are configured.

Right now I have an issue with this. I have for example an InputField and its binded to an numeric attribute.

In the browser when I type letters, the Webdynpro standard message shows up but it is in german language.

Currently my browser has EN(English) and my user in portal has ES(Spanish), so I dont know where that German message comes from.

Any help would be appreciated!
