• Transfomers should now assume they work with just one locale - no need to be able to track several locales all at once.
• Simplify i18n support:

  • BasicTransformer#i18NPropertyName becomes unnecessary - we don't need to set it externally, we can inject I18NAuthroingSupport and generate i18n-aware property name via it internally.

  • TransformedProperty's i18n-related methods (hasI18NSupport and fireI18nValueChange) become also redundant since TransformedProperties will be regenerated.

  • For read-only state support: add read-only state setter/getter to Transformer interface and make TransformedProperty delegate to it:

    @Override
    public boolean isReadOnly() {
        return super.isReadOnly() && transformer.isReadOnly();
    }

  • Delegating transformers should adapt to one locale case:

    • i.e. 

...

• • • DelegatingMultiValueFieldTransformer#items which tracks separate items for all locales - should be replaced with a single item for the current locale.

Other consequences:

• DefaultI18NAuthoringSupport#i18nize() wouldn't be needed any longer - all the ugliness could go away.

• Default values and read-only states would be much better and logically respected during locale changes since FieldFactories would re-apply those on form re-generation.
