I have a cfform flash in an application. I want to be able to set the 
required="yes" on a form field after a user checks the checkbox above it. SO 
for 
example, if the user checks the "I have my keys" box, then the "keydate" form 
field becomes required.

I've tried it the same way for the enable attribute, but I get error that 
required attribute is not boolean like the enable attribute. 
(enabled="{haskeys.selected ? true : false}"). I was using this for enable the 
field, but then I wasn't sure how to use this code if the form is being 
prepopulated from a query and the checkbox is already checked?


<cfform action="" method="POST" name="myform" width="850" format="Flash" > 

<cfinput type="Checkbox" name="haskeys"  label="I have my keys" visible="Yes" 
enabled="Yes">

<cfinput type="DateField" name="keydate" width="100" label="Date My keys were 
Provided" required="" size="20" visible="Yes"  value"">

<cfinput type="submit" value="Submit" name="submit">
</cfform>
