Before 6.7, we can place the properties file under webapp/locales, then web client load the plugin, it can find the proper properties file according to the locale value, but now, this mechanism seems not to be working any more.
The only way is set the resource file name and then place the resource file without locale in the name to the locales.
Just like the sample custom-object-ui, all the other samples are not working now.
<resources baseUrl="locales/"> <resource>com_vmware_samples_customobject</resource></resources>
