Hi Massimo,
Probably (and probably not) because I manually delete applications/
myapp/uploads/*.jpg, somehow I encounter an exception when gonna
display a crud.update(...) form.
The error traceback:
......
File "C:\DOWNLOAD\google_appengine\web2py\gluon\html.py", line 452,
in _traverse
newstatus = c._traverse(status) and newstatus
File "C:\DOWNLOAD\google_appengine\web2py\gluon\html.py", line 452,
in _traverse
newstatus = c._traverse(status) and newstatus
File "C:\DOWNLOAD\google_appengine\web2py\gluon\html.py", line 452,
in _traverse
newstatus = c._traverse(status) and newstatus
TypeError: 'NoneType' object is not callable
Then I add some logging before gluon.py/html.py line 452, and see:
WARNING:root:c=<tr id="crude_products_sold_crude_oid__row"><td><label
for="crude_products_sold_crude_oid"

td><td>3</td><td></td></tr>, c._traverse=<bound method TR._traverse

WARNING:root:c=<td>3</td>, c._traverse=<bound method TD._traverse of
<gluon.html.TD object at 0x0219D8F0>>
WARNING:root:c=3, c._traverse=None
Therefore I suggest changing line 445 of gluon/html.py from:
if hasattr(c, '_traverse'):
to:
if hasattr(c, '_traverse') and c._traverse is not None:
At least it won't break anything else.

Iceberg
