Hello, I've been combing the velocity docs/faqs and haven't found an answer to the following: How do I get nulls into context variables? For example, in some .vm file I would want to do:
#set ( $foo = $bar.someBigExpensiveOperationThatMayReturnNull(..) ) #if ( $foo ) ... #end But _don't_ want to do: #if ( $bar.someBigExpensiveOperationThatMayReturnNull(..) ) #set ( $foo = $bar.someBigExpensiveOperationThatMayReturnNull(..) ) The problem is $foo won't be set to "null" if velocity sees a null and even worse, the prior value will be used. I've noticed that the Context class extends from Hashmap which does not allow nulls but this seems like an oversight? IMHO of course :) My situation is further worsened since I'm mainly working in Texen/Anakia which limits code objects i can place in the context to use as "helpers" that aid in this functionality. Any insights would be greatly appreciated? russ -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
