I know it, but in that case I didn't want to use __init__.

When i make a search i get "There is no data matching this Myfolder query". See
different tests below.

No error, no traceback. Neither when cataloging, neither when searching.

I try to search all the object where b['one'] = 'un'. I use the input form
generated by the ZSearch interface.

I typed 'un' in the b field of the input form 
#as expected i got "There is no data matching this Myfolder query"

I type 'un' in the b['one'] filed of the input form
#i expected one object to be returned i got "There is no data matching this Myfolder query"

Maybe my example was bad but some values of my dictionary could be long
text. That's why I also try it with Textfield. But forget the Textfield.


Here other details of what i have done:
**Metatables**
b
a
b['one']

**Indexes**
b
a
b['one']


I then used Find objects to catalog (i have just one for the test).
**Status**
1 object are in b
1 object are in a
1 object are in b['one']

I created a ZSearch Interface.

Then: 

Test1.
in my input form
b = 'un'
(other fields empty)
result ====> "There is no data matching this Myfolder query".

Test2
in the input form
a=a_content
result =====>
b = the b dictionary
a = a_content
b['one']     #here i expected b['one'] = 'un'


Test 3
in the input form
b['one'] = 'un'
other fields empty.
result ====> "There is no data matching this Myfolder query".


And i am sure the content of b['one'] is 'un'. (I tried my_instance['one'], and
got 'un' as expected).

It seem that when caloging, ZCatalog didn't "find" the b['one'] element.
Bad syntax?

Hope i have given enough details and thanks again for your patience.
