You can write code like
if ("mycomponent" in this)
{
this["mycomponent"].doSomething( )
}
to avoid an FTE with mycomponent does not exist.

Hi,
Oftentimes I
need to check if a component( for example a TextInput) exists before
populating it with data.
The
getChildByName( )is the only method I know of, that can do this.
I wish there was
a getChildById( ) as well, so I wouldn’t have to set the name for all my
components( could be hundreds )in addition to their id.
[
If the
component( myComponent ) doesn’t exist:
this[“myComponent”]
throws the RE ReferenceError: Error #1069
and
this.contains( myComponent)
doesn’t compile of course
1120: Access of
undefined property myComponentId.
]
I know,
Christmas time is over, no more gifts for us from Adobe:)
Should I put it on
my next flex-xmas list?
Or do you guys
know about other ways of checking the existence of components? Any input would
be much appreciated.
Cheers,
Ondina
