Hi Paul,
How would you go about making form components dynamically
requirable? The Required class does not allow its required
property to be changed. I'd imagine there's some easy solution to
this, but I'm scratching my head trying to figure it out. Any help
would be appreciated.
In case anyone is interested, I came up with a solution. The idea is
to dynamically add or remove the validator, rather than try to modify
its state. An example of how I did it is below:
In the spec:
<component id="blah" type="TextField">
<binding name="displayName" value="literal:Blah"/>
<binding name="hidden" value="true"/>
<binding name="validators" value="blahRequired"/>
</component>
In the page class:
@Bean
public abstract Required getRequired();
.
.
.
public Validator getBlahRequired()
{
if (true == someCondition)
{
return getRequired();
}
return null;
}
This seems to be working pretty well now. I like being able to move
all of that logic into the page class too, rather than having it
kicking around in the spec.
