Error : Grid (Table) Component Fails to Display Data and Triggers Error

[Mudassir200]

📋 Description:

When using the Child Table (Grid) component in Frappe CRM:

1. If the initial value is an empty string (""), the component tries to map() over it during mounted, which leads to a page-breaking error because map is not valid on a string.
2. When data is added using the push() method to the definedModel variable, it does not emit a change event.
3. As a result, the component's computed value does not update, and the selected data is not displayed.

🛠️ Steps to Reproduce:

1. Use Child Table in a doctype then add in layout
2. Open Modal for create reocrd
3. Also Add Values then check

Notice:

Component breaks on mount.
UI doesn't reflect updated values.

✔️ Proposed Solution:

1. Fix for Empty String Handling:
   const rows = defineModel({ default: () => [] }) // update this line
2. Ensure Reactivity with push:
   rows.value = [...rows.value, newRow] // update this line in addRow
