Drupal Community Portal

I test migration from D6 to D7 and have problem afterwards, in D7, with integer fields which are not required. When I add a node and leave that field empty, I get a pdo exception.
Does it happens to you or not?
I use easyphp 5.3.8.1.
To simplify I made the following test
I did a new install drupal 6.24 English
I add cck module last version, I enable text and integer.
I add a new content type with an integer field, not required.
I add 3 contents (not important).
I migrate from D6 to D7, core, then cck
When I add a new content of that content type, with no value for integer, I get :
PDOException: SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'field_entier_value' at row 1: INSERT INTO {field_data_field_entier} (entity_type, entity_id, revision_id, bundle, delta, language, field_entier_value) VALUES (:db_insert_placeholder_0, :db_insert_placeholder_1, :db_insert_placeholder_2, :db_insert_placeholder_3, :db_insert_placeholder_4, :db_insert_placeholder_5, :db_insert_placeholder_6); Array ( [:db_insert_placeholder_0] => node [:db_insert_placeholder_1] => 6 [:db_insert_placeholder_2] => 6 [:db_insert_placeholder_3] => nicole [:db_insert_placeholder_4] => 0 [:db_insert_placeholder_5] => und [:db_insert_placeholder_6] => ) in field_sql_storage_field_storage_write() (line 448 of C:\Program Files (x86)\EasyPHP-5.3.8.1\www\cms\cmsd624en\modules\field\modules\field_sql_storage\field_sql_storage.module).
I posted this cck issue without reply.
Lately I posted that issue here :http://drupal.org/node/1433834
As you can see, they ask more tests.
Can someone reproduce my test?
For someone used to migration, it's an half an hour job.
Thanks for helping Drupal system
