Consider this question closed. I found answer by looking at hivemodule.xml of tapestry framework. For anyone who should have similar problem in the future:
To make T4 use new user defined TypeConverter you need to contribute to the configuration point by adding entries in hivemodule.xml. Eg: <contribution configuration-id="tapestry.coerce.TypeConverters"> <converter class="org.apache.tapestry.IRender" object="service:IRenderToStringConverter"/> </contribution> <service-point id="IRenderToStringConverter" interface="tap.IRenderToStringConverter"> <invoke-factory> <construct class="tap.IRenderToStringConverter"/> </invoke-factory> </service-point> cheers --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
