Your property isn't really 'blah'. It is 'blah[0]',
'blah[1]', etc. So if you use the full property for a
field for the ActionErrors key, then you can retrieve
it next to each field.
ActionErrors errors = new ActionErrors();
errors.add("blah[0]", new ActionError("error.msg"));
<html:error property="blah[0]"/>
This type of question would be a good question to ask
on the Struts User list. And any development
suggestions are good to post to bugzilla if there
really is a feature request you want so they don't get
lost.
