My obj1 has related "one to one" to obj2,
And my obj2 has related "one to one" to obj3.
Can I edit obj3's field in obj1's Edit page by using related field?
I've tried to use related field through obj2 as connector (obj2 has related field to obj3) but it said field is read only, Like this picture.
Or is there other way to do this situation?
PS. I use rollbase release 3.2.4.
There is no OOB configuration option to make this work.
You can considering using AJAX api to set a related records field value by taking input via custom form control. However, this will not be straight forward to acheive for all field types. For example, for a picklist field we need metadata like set of valid options, similarly for a look up field. Additionaly, users editing the form should have edit permissions against the related record object type.
This option can be considered for simple field type.
