I want to trigger the UpgradeModule method in my controller class when a module upgrade is performed (this is DNN 5.62 by the way).

As far as I can see I have set up everything perfectly (as per Peter Donker's post:  DNN 5 installer does IUpgradeable differently), but no record is being added to the EventQueue table (and my method is not being called, no doubt because of this).

I have checked (and double checked!) the following:
  • the business controller class implements IUpgradable
  • the module definition has Upgradeable as a supported feature (SupportedFeatures = 4 in table)
  • the business controller class plus assembly name is registered in the module definition
  • the EventMessage section of the manifest file is set up per the blog post above
What could be going wrong? What else can I check?

FYI - the only "unusual" thing about my manifest file is that there are multiple packages within the one file (several modules, plus a skin object & a library). The package I have attached the EventMessage section to does not have a Script component (the SQL upgrade scripts are attached to another module package). The business controller class is also in an assembly that is part of another module.

that all sounds correct, im afraid all i can suggest is that you download the source package and try to debug through it.

Figured it out! Cathal - could you look over this to see if what I am saying is valid:

First off - I lied .... I didn't follow Peter's blog post exactly. The correct position for the < eventMessage />  node is after < desktopModule />  - I had it inside < desktopModule />. This is what the Wiki article Module Component implies,which I had also been following.

Cathal - can I correct the article, or is it maybe accurate for DNN 6 and not for DNN 5?

After correcting the position of the < eventMessage /> node, now UpgradeModule events were being added to the EventQueue table. But there was one further problem .... the event hook was set to Application_Start_FirstRequest, and DNN was not picking up these events and processing them. Why? Some digging in the source code revealed that these event types are picked up by the UrlRewrite module, and I had swapped out the native UrlRewrite module for a 3rd party module that obviously did not implement this.

Another Cathal question - could this event type possibly be processed by the core and not the UrlRewrite module, or could the event type be changed to Application_Start for module upgrades (I'll put the request in Gemini if it is valid)?

Hello,
glad you sorted it out - the wiki article also does appear to be wrong (ive updated it) - BTW the wiki is a community resource so feel free to edit/add new pages at any time.

As to the event hook, I think that is incorrect as the friendlyurl is a provider so there is no guarantee that it will always be there -instead the code should be in the core (its probably just there from the days before the code was extracted out into a provider)-please log that as a bug at support.dotnetnuke.com

Thanks,
Cathal
