I’m having the following problem with a checkbox
I have a checkbox list that is dynamically loaded (as the items that exist in the bank a checkbox is generated). I currently have only three items being ids 1, 2 and 3. Within the system when I have saved the object containing a list of these items is passed by some validations, and when it returns to the View the system validation message is displayed, if I select a checkbox for ID 2 or 3 the flow works normally, when I select the checkbox with id 1 all part of the backend works normally but when it returns to the view and when trying to render the checkbox again returns the following error:

I saw some responses related to similar errors but in different situations, I can’t identify what can be, since it only happens with ID 1 in others works perfectly
EDIT
I ran a test removing the item with id 1 from the list before rendering by selecting the first checkbox from the list of the same error when selecting the second works normal
If when you select Ids 2 and 3 everything works, but only for ID 1 it doesn’t work, try comparing the fields between these objects, as it seems that some field related to ID 1 needs to be converted/treated.

Opa Renan, I had already checked this, but I took another look for consciousness disengagement and there are no differences in the objects only the values of the same attributes
