Question

When I click a row in the datagrid, the “PeopleDetails” state is loaded. On the details state, I have a checkbox. This checkbox was automatically generated when I created the form. This is because the field in the People table is Boolean.

I actually do not want to have a checkbox, but I want the value Yes/No printed next to the label.

So I write some AS code embedded in the MXML code:

<s:Form includeIn="PeopleDetails">
 <s:FormItem label="Is Present?">
  <fx:Script>
  <![CDATA[
  if(person!= null ){
   if(person.present==true){
    Alert.show("Test - Yes");
   }
  }
  else{
   Alert.show("No");
  }
  ]]>
  </fx:Script>
  <s:CheckBox id="personCheckBox2" enabled="false" selected="{person.present}"/>
 </s:FormItem>
</s:Form>

Just for testing purposes, I have Alert popups. Eventually, I would change to printing to screen the values Yes/No.

The problem:
-I do not know how to test whether the attribute present in the object person is true or false.
In the above, I get a FB complaint 1120: Access of Undefined property person.

If I remove the AS code, the checkbox works fine. The checkbox uses person.present to know whether it should be checked or not. Why cannot I use person.present to do the if-else test?

I would appreciate any help on this.

If I’m reading you right, you want a Yes/No value rather than a checkbox, this should do it for you:

Change :

<s:CheckBox id="personCheckBox2" enabled="false" selected="{person.present}"/>

To :

<s:Label text="{(person.present)?'Yes':'No'}"/>

So the new form looks like this :

    <s:Form includeIn="PeopleDetails">
        <s:FormItem label="Is Present?">
            <s:Label text="{(person.present)?'Yes':'No'}"/>
        </s:FormItem>
    </s:Form>
