Maybe this will help you [?] This way I always test if variable is not null
http://velocity.apache.org/engine/devel/user-guide.html#Conditionals ............. The *#if* directive in Velocity allows for text to be included when the web page is generated, on the conditional that the if statement is true. For example: #if( $foo ) <strong>Velocity!</strong> #end The variable *$foo* is evaluated to determine whether it is true, which will happen under one of two circumstances: (i) *$foo* is a boolean (true/false) which has a true value, or (ii)* the value is not null*. Remember that the Velocity context only contains Objects, so when we say 'boolean', it will be represented as a Boolean (the class). This is true even for methods that return boolean - the introspection infrastructure will return a Boolean of the same logical value. ............ 2009/7/28 Captain Cid <captain_...@indiatimes.com> > > I have a template containing some variables to be rendered from context. > Is there way by which i can know if all the variables are present in the > context, otherwise throw an error. > -- > View this message in context: > http://www.nabble.com/checking-if-all-variables-are-present-tp24696207p24696207.html > Sent from the Velocity - User mailing list archive at Nabble.com. > > > --------------------------------------------------------------------- > To unsubscribe, e-mail: user-unsubscr...@velocity.apache.org > For additional commands, e-mail: user-h...@velocity.apache.org > >
