I am using Struts + Velocity in a Java application, but after I submit a form, the confirmation page (Velocity template) shows the variable names instead an empty label, like the Age in following example:
Name: Fernando
Age: {person.age}
Sex: Male
I would like to know how to hide it!
You can mark variables as "silent" like this:
$!variable
If $variable is null, nothing will be rendered. If it is not null, its value will render as it normally would.
You will also need to be sure and use the proper syntax. Your example is missing the dollar before the variable. It should be $!{person.age}, not just {person.age}.
