Re: [Axualize-users] Strange behavior in boolean logic?

[Russell W. <rus...@ya...>]

Frank,

Here is your problem:

<boolean id="ans">
  <object idref="validator" method="validateForm">
    <object idref="fields"/>
  </object>
</boolean>

The boolean tag has only two forms:

<boolean>true</boolean>
<boolean value="true"/>

Of course you could substitute "true" for "false", but hey I am an optimist. :)

The primitive tags are used to create instances of primitives. Since you
already have an instance you do not need to do this. Your method returns a
boolean so you can just put it in the model like this:
<void idref="validator" method="validateForm" id="ans">
  <object idref="fields"/>
</void>

This form would have also worked but is very redundant and I would not
recommend it:

<void class="java.lang.Boolean" id="ans">
  <object idref="validator" method="validateForm">
    <object idref="fields"/>
  </object>
<void/>
