Conditional Binding

Rhythmyx Technical Discussion

Is it possible to create a conditional binding parameter so that the binding variable only gets set if the content item has the associated property?

I want to do something like

if ($sys.item.hasProperty(“rx:XXXX”))
$sys.item.getProperty(“XXXX”).String

Nick.

Nick,

Yes, it’s possible. See this thread http://forum.percussion.com/showthread.php?t=508 for an example using a different property. Specifically, see posting #9 for the example code.

I’ve just started with Velocity templates and bindings, but I’ve been using something along the lines of:

$rx.cond.choose($sys.item.hasProperty(‘XXXX’),$sys.item.getProperty(‘XXXX’).String,’’)

Your mileage may vary

RLJ,

Can you give an example of how this would work with bindings?

If I enter

if ( $sys.item.hasProperty("rx:XXXXX") ) 
{ $sys.item.getProperty("rx:XXXXX") ; }
else
{ else ""; }

into the JEXL expression part of the binding I get an error on assembling the item.

Try this:

if ( $sys.item.hasProperty("rx:XXXXX") ) 
{ $xyz = $sys.item.getProperty("rx:XXXXX") ; }
else
{ $xyz = ""; }

Thanks.
That works perfectly.
