That seems to be a bug. Among other things, resourcebundle_iterator_read calls resourcebundle_extract_value instead of resourcebundle_array_get (which handles fallbacks via resourcebundle_array_fetch).
I'm not sure if the fix is that simple though, as that only fixes getting of values, but the iterated range probably still doesn't include the fallback values. What would the expected behavior be for iterators? Should it iterate over all contents, including fallbacks? You sent another message to the list earlier which appears to be describing a similar, but different problem where values are null when iterating? - David On 16.08.2010, at 23:05, Joel Sahleen wrote: > All, > > I am working on a large-scale internationalization project that use the intl > extension.
