Need logging around the DetectUpdateBegin/DetectUpdate/DetectUpdateComplete events in your MBA. Are you seeing detect being triggered twice?
If you don't return Result.Ok, then the engine won't download and parse the feed. If you return Result.Ok (which seems to be the case since you say in fiddler you see the feed being downloaded), then the feed parsing will cull any entries it doesn't see as valid (missing app id, bad version, etc). Then for each successfully parsed update it will call back to DetectUpdate to let the BA decide what to do. I don't think the size should matter. Exiting an update early should not cause an issue. The A bundle will download the B bundle, execute it, and then cleanup via a MoveFileEx which moves the bundle B from the per-user cache to temp and flags it for deletion. I don't think today the engine parsing would support modifying the feed URL. Since it's declarative when you create your bundle, I don't know if we'd want the BA to modify what the bundle developer defined. Note, there isn't anything preventing you from doing it like you used to, but then all the parsing is left on your side. -----Original Message----- From: Phill Hogland [mailto:phogl...@rimage.com] Sent: Tuesday, July 22, 2014 10:49 AM To: wix-users@lists.sourceforge.net Subject: [WiX-users] wix39.720 Burn DetectUpdate - fails to detect new version I transitioned my mba code to model the WixBA UpdateViewModel code in wix 3.9.720. Initially it detected the latest new update and appeared to work as expected. However the more I play with it I seem to run into a problem multiple times. I am still a little unsure of how I get to this problem, but I think it is as follows. Create Bundle A, move to test box. Create Bundle B, stage to web site. Launch Bundle A, and after checking 'Update Available' is indicated. (Also in the log the message fro DetectUpdate indicating a 'Potential update' is available. (At this point one can either exit Bundle A or apply the new update. I am not entirely sure of the relationship to the following, but I think exiting is probably more related.) Create Bundle C, and stage to web site. Launch Fiddler to watch the http traffic. Launch Bundle A. Fiddler shows a feed to Bundle C was retrieved. Bundle A shows 'Up to date'. The log does not have the DetectUpdate log message "Potential update..." I have seen this behavior both in a first time install (but I think always after a bundle was previously launched) and in a maintenance scenario with Uninstall, Repair, and 'Up to Date' (even though the feed shows a newer version). My atom feed has the bundle size in it, otherwise it is same as wix39 feed. I tried setting the bundle size to zero in the feed and that did not impact this behavior. On another note, unrelated to the above, I need to figure out how to modify the feed Url prior to downloading the feed at runtime. I had this working in the old code, but I don't see where to do this as the feed appears to have been downloaded by the time the event handlers are fired.
