Hi All,
Hope all is well.
Attached is a patch to the I18nTransformer to support transform
time configuration changes. The parameters given at definition time
can now also be overridden as map:parameter's to change the defaults
specified at definition time (all except the cache-at-startup option).
eg.
<map:transformer name="i18n" src="org.apache.cocoon.transformation.I18nTransformer">
<catalogue-name>messages</catalogue-name>
<catalogue-location>translations</catalogue-location>
</map:transformer>
...
...
...
<map:transform type="i18n">
<map:parameter name="catalogue-name" value="msg"/>
</map:transform>
Hope it's all ok. Hope everyone has a great weekend.
Cheers,
Marcus
