I confirm the second part of the problem.

Inline edit uses ODBSet(), which uses the "jset" AJAX call to mhttpd which does not extend string variables.

This is the jset code. The best I can tell it truncates string variables to the existing size in ODB:

db_find_key(hDB, 0, str, &hkey)
db_get_key(hDB, hkey, &key);
memset(data, 0, sizeof(data));
size = sizeof(data);
db_sscanf(getparam("value"), data, &size, 0, key.type);
db_set_data_index(hDB, hkey, data, key.item_size, index, key.type);

These original jset/jget functions are a little bit too complicated and there is no documentation (what exists is done by me trying to read the existing code).

We now have a jcopy/ODBMCopy() as a sane replacement for jget, but nothing comparable for jset, yet.

I think this quirk of inline edit cannot be fixed in javascript - the mhttpd code for "jset" has to change.

K.O.
