Velocity counters and obj access

[dizzi <D....@sh.cvut.cz>]

Hello,
I have 2 questions

1.
Is there way how to use 2 velocity counters in 2 nested loops?
(i didnt test it but my colleague had problem with that)

2.
I have this object (below), why I cant access to rok, mesic and den 
arrays without defining getters (ive tried to make them public too) like 
this

#foreach($rok in $datum.rok)
	$rok
#end

even with getters defined, i cant access to members of inner class
#foreach($den in $datum.den)
	$den
#end
this works fine, but when i try

$den.svatek or $den.isSvatek()

velocity complain that $den.svatek/isSvatek() cannot be resolved.

thx d.


Datum dtime = new Datum();
request.setAttribute("datum", dtime);



public class Datum {

	class Den {
		public boolean svatek=false;
		public boolean vikend=false;
		public String den=null;
		@Override
		public String toString() {
			return den;
		}
		public Den(int den) {
			this.den=Integer.toString(den);
		}
		public String getDen() {
			return den;
		}
		public boolean isSvatek() {
			return svatek;
		}
		public boolean isVikend() {
			return vikend;
		}
	}
	
	String[] rok=new String[3];
	String[] mesic=new String[12];
	Den[] den;

	public Den[] getDen() {
		return den;
	}
	public String[] getMesic() {
		return mesic;
	}
	public String[] getRok() {
		return rok;
	}
}

not sure quite what you mean, but i suspect that you can't do that.
you can always define as many of your own counters as you want though:

#set( $anotherCounter = 0 )
#foreach( $foo in $foos )
 #set( $anotherCounter = $anotherCounter + 1 )
 ....
#end

Velocity doesn't provide access to class members, only to public
methods in public classes.

that's because the Den class isn't declared public.  Velocity will
only provide access to public methods on public classes.
