I got this error in some template

the minimal that i got for the error is the following : http://pastebin.com/7jik0rHJ

removing some of the vardecls or removing the template part fixes the error.

It seems that some string, e.g. the name of some generated class, becomes too long when there is a large collection of {var decls + template args} leading to long strings with type information.

Minimal test:

application test

page root(){
	placeholder x test(1,2,3,4,5,6,7,8,9,10,11,12,13,14, LongNamedEntityWithALotOfCharactersInIt{}, LongNamedEntityWithALotOfCharactersInIt{})
}

entity LongNamedEntityWithALotOfCharactersInIt{
	
}

ajax template test( arg1 : Int,arg2 : Int,arg3 : Int,arg4 : Int,arg5 : Int,arg6 : Int,arg7 : Int,arg8 : Int,arg9 : Int,arg10 : Int,arg11 : Int,arg12 : Int,arg13 : Int,arg14 : Int, e1:LongNamedEntityWithALotOfCharactersInIt, e2:LongNamedEntityWithALotOfCharactersInIt ){
	var arg15 := 0;
	var arg16 := 0;
	var arg17 := 0;
	var arg18 := 0;
	var arg18 := 0;
	var arg20 := 0;
	var arg21 := 0;
	var arg22 := 0;
	
	
	submitlink action{}{}
}

It turns out that some class has a very long name, too long for the file system to use that as a file name (Mac OSX in my case, which has a limit of 255 chars).
