test-data.h5 (18.1 KB)
In the attached file I’ve added a single row of data of a compound type as an attribute and as a data-set.
HDFView can display the data-set but when I double click the attribute I get “Error occured when instantiating TableView class.”
Could be an HDFView bug. The h5dump output is shown below. What happened to that dataset /MeasurementConfigurations? How did you create this file?

What version is hdfview? We have fixed a number of issues since the release of hdfview 3.1.1
Current development (soon to be released) does display correctly.

What do you mean ‘what happened to …’? If you mean why is it only one row, then it’s just a test.
My code here: https://github.com/PhilPJL/HDF5Test
We do have binaries of the latest hdfview development for some platforms we could make available.
On my system, fedora 35, i have development builds of both hdf5 and hdfview that display this file correctly.
HDF5 1.12.2 will be released within a couple of weeks and HDFView 3.2.0 (based on hdf5 1.12.2) should be released shortly after that.
