Error handling with

[Malcolm Edgar <ma...@gmail.com>]

Hi All,

I have just been reviewing the new error handlingin Velocity 1.5-dev.
One change I have observed it that an invalid macro call, passing 2
arguments instead of one will log an error message:

[Velocity] [error] VM #writeForm: error : too many arguments to macro.
Wanted 1 got 2
[Velocity] [error] VM error writeForm. Null AST

However it will not throw an ParseErrorException like it used to in
1.5-dev. Please see the example below for the earlier behaviour:

http://www.sunvolt.com/click-examples/exception.htm?actionLink=brokenBorderLink#

I prefer earlier approach, as the error is explicit. The new approach
logs an error message, but beyond that you would not have known that
an error occured. The #writeForm() call is not even rendered, as is
done with an invalid object reference.

regards Malcolm Edgar
