Subject import hangs

[mhmoed]

When trying to import subjects from an Excel file, the importer gets stuck on the first step ('Import file').

After uploading the Excel file, setting the type of data, study and data template, and clicking 'next', the wizard returns to the same page instead of going to the next step (i.e. assigning properties). The Excel file appears to be loaded correctly, as a working, correct preview is shown at the bottom of the page.

The log looks clean, as does the output in Safari's debug console (web inspector). The log of a single import try is stored in this gist. I'm using the latest version (0.9.5.4, commit 033c418) compiled with Grails 2.4.5.

Could you please provide the Excel file you tried to import?
