[stringtemplate-interest] Default Null Option

[Rene Villeneuve]

Hi guys, 

I am not sure if it's the right place to ask my question, but I could
not find a forum anywhere on the site. 

I just started to use string template and while I was able to get
everything set up and working, I hit a little snag earlier today. In
essence, all I'm trying to do is to ensure that every time there is a
null value, instead of skipping it will format correctly with an empty
value. While I can do it through the template, I want to do it
programmatically to ensure that it's always there, as I am not the only
one developing templates. I got it working by creating an anonymous
class, extending StringTemplate, that got an overridden parseAction in
which I modified the list of option coming from parse.action by adding
null every time. 

I also had to modify the way the parser was working to make sure it
would spawn sub template with the valid overwritten parseAction method.
Now it's working, but I am sure I am not using the right method. There
must be a simpler way to add a default option that will be applied to
every element in the template, I just cannot find it. Any form of help
would be appreciated.

Thanks!

Rene Villeneuve
