Thanks for your reply.

I have another question, how to set the field invisible in a one2many field,like:
<field name='condition_field' />
<field name='one2many_field'>
<tree>
<field name='field1' / >
<field name='field2' / attrs={'invisible':[('condition', '=' , True or Condition)]}>
</tree>
</field>
I tried to set the field like this, but fail.
And then set the attrs={'invisible':[('field1','=', True or Condition)]}
It just set the field unclickable on the condition, seems like it verifies on every field and change state for fields that meet the condition, not every field.
Do you have any clue? Thank you.

Can you please specify the fields and their types so I can help?
