Hi Izaak,

I reproduced the problem you described. We will investigate the feature to see
if there is a bug or some limitation in HDFView.

Thank you very much for reporting it.

Hello all,
Regarding external links, should one be able to cascade or recurse down multiple external links? In HDFview-2.7 I can't see the contents of an externally linked group more than 1 level deep. Should I expect similar behaviour in a compiled Fortran code?

For example, I have a set of files named 1.h5 to 9.h5 each containing multiple groups and data sets. Files 1.h5 to 8.h5 also contain an external link, '/next' which, as you can see, lives at the top (root) level of each data file. This soft link then points to the root group of the next hdf5 file. For example, 1.h5/next --> 2.h5/, 2.h5/next --> 3.h5/, etc. In HDFview-2.7 if I were to open 1.h5/next I can see the entire contents and meta data of 2.h5/, but 1.h5/next/next won't open, although it appears I can see the correct meta data.

Is this the desired behaviour of HDFview or a bug?
Can I expect to be able to derefrence/address a chain of multiple external links in a compiled program using the HDF5 API?

Thanks,
 Izaak Beekman
