Hi Today I've experienced a weird behaviuor from MonoRail while using elements mention in the topic.
Imagine the following: 1. I have a custom extension, which loads menu items from configuration and then uses UrlHelper to build links for those items. 2. On one of the pages I use ActionHelper's Render method 3. The whole thing explodes inside Controller#DisposeFilters() with NullReferenceExpception I spent some time looking into that issue and it seems the problem lies inside ActionHelper. 1. ActionHelper creates UrlInfo without supplying AppVirtualDir, which causes UrlBuilder to fail inside extension 2. Because extensions fire before other MonoRail steps, the disposing of Controller happens before it has been contextualized 3. The above is the reason of NullRefereneException (the null is in fact Controller#context) There are a few weak spots I thnk should be fixed: 1. Dispose should be invulnerable to NullReferenceException. Extension failing is a good reason not to assume, that all Controller's properties will be set. Other solution would be actually contextualizing *before* anything could go wrong 2. Another UrlInfo constructor should be used for ActionHelper. That is the direct reason for my problem. I'm not sure how to supply all the required parameters correctly though. 3. Last issue is exception handling inside MonoRail, which hasn't just once failed me. This is not the first time I've encountered MonoRail display not the actual exception, which tends to be quite misleading. It took me quite a lot of digging to figure out what's going on. On the other hand thank god MR is open source. I doubt I would be able to find my solution for a simmilari issue with ASP.NET... ;) -- You received this message because you are subscribed to the Google Groups "Castle Project Users" group.
