For collecting errors found in the 7th Edition.
I believe there is a bug in the code presented for
updateTags() in the Photorama app, page 469. Details are here:
@gc3182 – Good catch! And perfect fix.
We’ll get that fix in for the next printing. We’ll also update the online solutions, along with adding a comment explaining the fix (since the 1st printing obviously won’t have the fix in place).
