Changeset 27282 for main/trunk/greenstone2/macros/style.dm

Message:

When retrieving a collection's existing usercomments, the collection could be open in GLI and therefore locked so that the metadata retrieve fails with an error about this. The while loop in the loadUserComments javascript function needs error handling therefore, since the page load hangs otherwise during the meta retrieve loop as things seem to be retrieving something (an error) instead of meta and the loop keeps going.
