onAdd not firing

[demobiel]

Hi

my goal is to add a default attribute when elements are added and people should be able to choose from a popup menu the values.

I thought the "onAdd" event would be the good way to go, so that I could add the attribute to it and the given values.

However I tried the following code (the demo.js file is intact besides this change):

events: { onUpdate: console.log, onSave: console.log, onAdd: (evt)=>{alert("something is added")} },

but the onAdd is never called... the same code for onUpdate works, but is of course triggered way to much.

Am I misunderstanding this, or is this a bug?

thanks!

kind regards

Andries

Thanks for reporting this. The onAdd callback was indeed defined but never invoked — confirmed as a bug.

Fixed in #447 which:

• Wires up onAdd to fire alongside onAddRow/onAddColumn/onAddField (same pattern as onUpdate)
• Adds onRemove for symmetry (also fires alongside onRemoveRow/onRemoveColumn/onRemoveField)

After this fix, you can use:

events: {
  onAdd: (evt) => {
    // fires whenever any component (row/column/field) is added
  },
  onRemove: (evt) => {
    // fires whenever any component (row/column/field) is removed
  },
}

8 new unit tests added to cover these callbacks.
