Spring MVC 3 Error suggestions

[flavouski]

I am currently using spring's form taglib and am displaying errors when received back from the server and it works great:

<form:errors path="*"/>

What does everyone do for ajax errors? Do you just plug them into about the same spot, use error codes, or ...?

Thanks

When you say AJAX errors..are you referring to async calls made to the server? If so Shouldn't they be handled/processed in the same way your other validation calls are happening?

yes, asynch. I'm unsure how to plug them into springs taglibs. When I receive them back from the server-side I get them in JSON format.

Currently what I do is have a set of errors that exist in separate divs (that are invisible) and have a error code associated with each. When i receive an error from the server I just make the div with the proper error code appear. That is just for JSON, for everything else I use spring's form:errors taglib.

But I was interested in how other people handled it and if there was a cleaner way?

In my case all calls , sync and async are validated by the same validators and are accessed on the jsp using form:errors (i don't use a separate response mechanism for async calls but rather use the same mvc model object paradigm to propagate errors). I dont use divs etc to show hide dynamically but rather use tiles+Spring JS/AJAX to reload specific parts of the page (in the case of a async all). This way all my requests/response are handled in the same way and the error validation is also central.

ah yeah, I forgot about that. I didn't mention I was on Portlet MVC, but I forgot that there are parts (like the marshaller) the portlet code can't use.

Interesting on the Spring JS, haven't checked that out. Thanks!
