Re: [WebMacro-user] Accessing property via "Unary Accessor"

[Eric B. R. <eb...@tc...>]

WebMacro has to be precise in its spelling of properties because it's  
the only way to provide predictable results.

For example, what if your Bean also had:
	gettitle()
	getTitle()
         getTiTle()
	getTITLE()
	gettitlE()
	etc, etc

Which one would you want WebMacro to choose when the template  
designer typed $board.title?

This is somewhat of a hack, but if you want case-insensitive matching  
for property names, don't expose them at all through member  
functions, but instead implement a single get() method:

	public Object get(String proname) {
		return _propmap.get(proname.toLowerCase());
	}

This would allow any of these to return the same value:
	$board.title
	$board.Title
	$board.TITLE
	$board.TitLe
	etc, etc

But really, it's a horrible horrible idea and you shouldn't do it.   
Instead, just get used to WebMacro honoring the case of property  
names as they were defined in your class.  :)
