Child table strange behavior

Hi All,
I am using
ERPNext: v12.1.6 (version-12)
Frappe Framework: v12.0.16 (version-12)

I am facing a strange behavior on child table as below

I have this DocType

and this is the 2 linked childTables

and when i test the Doc, i found as below

any idea about why it behaves like that,
what is the mistake i made

Regards,

get sure that child table fields is not mark as read

it is not read only

Hello @Ahmed_F_Mostafa,

Make sure you have checked “In Grid View” in child table fields as shown below.

Hope this helps.

Yes i checked , all fields are marked as In Grid View

In your child table doctype, tick mark “Custom?” and then save it and reload your account.

as i understand , if i tick Custom , it will not be saved in myapp folder, but instead it will be in database.

i am developing these docs in application .

am i right or not?

I have found it ,

the parent doctype was referenced as “table multiselect” field in another doctype.
when i removed this reference or just change from “table multiselect” to link. it started to work normally.

according to this https://erpnext.com/docs/user/manual/en/customize-erpnext/articles/table-multiselect
the referenced doctype in “table multiselect” should be childdoc not parent.

thanks for all
