Cell is not editable

Error message

Cell is not editable

What it means

Default implementation of EnumeratedTableColumn.setValueOf(R, Object). Mirrors error 562 for the simpler EnumeratedTableColumn interface: columns are non-editable unless isEditable(R) is overridden to return true, and when editing is enabled the subclass must also override setValueOf. The default throws to signal an incomplete edit implementation.

Solutions

1. Override setValueOf(R row, Object value) in the enum constant/class so the edit is applied to the row.
2. Leave isEditable returning false if the column must remain read-only.
3. Pair every isEditable()==true column with a tested setValueOf override.

Example fix

// before
ADDRESS {
  public Object getValueOf(Row r) { return r.getAddress(); }
  public boolean isEditable(Row r) { return true; } // no setValueOf
};

// after
ADDRESS {
  public Object getValueOf(Row r) { return r.getAddress(); }
  public boolean isEditable(Row r) { return true; }
  public void setValueOf(Row r, Object value) { r.setAddress((Address) value); }
};

if (col.isEditable(row)) {
  // only call setValueOf if isEditable is true AND the column overrides setValueOf
}

try {
  col.setValueOf(row, value);
} catch (UnsupportedOperationException e) {
  if ("Cell is not editable".equals(e.getMessage())) {
    // no setter implemented; ignore
  } else throw e;
}

When it happens

Trigger: An enum-based EnumeratedTableColumn overrides isEditable(row) to true but does not override setValueOf(row, value). The table invokes setValueOf when a user commits an edit in that cell.

Common situations: Prototyping an editable enumerated table column; toggling editability on a column modeled after a read-only one without adding the setter; framework upgrades where the editable contract was tightened.
