[TYPO3-mvc] Localize Flashmessages and fluid form errors

[Matthias Krappitz]

Hi,

I just created a small extension with the extension_builder where there is 
one model with 4 fields and 2 of them must be nonempty (the annotations for 
that in the model are set). If I save in the frontend without these 2 fields 
being filled out, I get a Flashmessage and fluid form errors using the 
appropriate Viewhelpers <f:flashMessages /> ...<f:form.errors> ... 
{error.message} ... <f:if condition="{error.propertyName}"> <f:for 
each="{error.errors}" as="errorDetail"> {errorDetail.message} </f:for> ... 
</f:if> ... </f:form.errors>.

So my question is, how do I change the text of the Flashmessage and of the 
Form Errors to something more human readable and how can I localize these 
messages? What is the best practice for that? And where exactly do the 
current standard texts come from? Are they hardcoded in extbase core 
somewhere?

Best Wishes
