Last change on this file since 23012 was 23012, checked in by ak19, 13 years ago

Fix to bug causing depositor to crash library.cgi upon selecting a collection: code was previously looping on parameter names in args to substring them in order to compare them to a prefix. However, it also tried to substring them when the arg parameter name was shorter than the prefix. Fix was necessary in two locations (wizardaction and depositoraction).
