ArrayIndexOutOfBoundsException on NumberField<T>.setAllowDecimals

[icfantv]

Here's the code:

import com.google.gwt.core.client.EntryPoint;
import com.sencha.gxt.widget.core.client.form.NumberField;
import com.sencha.gxt.widget.core.client.form.NumberPropertyEditor;


public class MainEntry implements EntryPoint {


  @Override
  public void onModuleLoad() {
    
    NumberField<Integer> integerField =
      new NumberField<Integer>(new NumberPropertyEditor.IntegerPropertyEditor());
    integerField.setAllowDecimals(false); // throws an exception
  }
}

In theory, I think a developer might expect the allowDecimals property to be set implicitly to false because he/she is specifying an integer type with an integer property editor and integers are whole numbers.

If I don't call setAllowDecimals the field allows the . character which as previously mentioned violates the premise of having an integer field.

Fixed in beta 3 per release notes:
