I have a comboBox cell editor with some predefined values. The grid is loaded from a database and the cell's value can be just any, not only those listed in the combo box.
The problem is: a user starts editing that cell and then decides not to change the value, but it changes!

from gxt 2.2.3 Editor.java
Code:
  protected void onBlur(FieldEvent fe) {
    if (!allowBlur && editing) {
      completeEdit();
    }
  }
So I enabled allowBlur, but it didn't help. Now the combo box stays visible after blur.
Why not
Code:
protected void onBlur(FieldEvent fe) {
   if (editing) {
    if (!allowBlur) {
      completeEdit();
    } else {
      cancelEdit();
    }
   }
  }
