[Webwork-user] Re: Getting a value from a map

[Patrick L. <pli...@ho...>]

Followup:

Chaning line 407 in AbstractValueStack from:

value = ((Map) value).get(key.toString());

to:

value = ((Map) value).get(key);

Fixes the problem. I'm suprised this hasn't been noticed before. I wonder if
I'm doing something wrong?
