Mysterious nil function error
 

Hi All,
Combat Reticle occasionally causes an error on load - usually when loading a character for the first time, but also sometimes after fast travel (I think). The error message says:

CombatReticle_Update:3: function expected instead of nil
stack traceback:
CombatReticle_Update:3: in function '(main chunk)'

So, there is no function 'CombatReticle_Update' in my code. Where does this string come from? I'm guessing it has to do with either event registrations in the init code, or perhaps the control binding xml (<TopLevelControl name="CombatReticle" movable="false"><OnUpdate>...). Any ideas?

I do register several (4) events in the initial load function - is it possible that the game engine is calling to some of these before the are all registered? (I don't think that would cause the problem since all vars that are referenced in the handlers are already initialized)

Any help would be appreciated.

Try to change the order in your manifest txt file so the XML file will be executed after the lua file of the addon.
Otherwise the "OnUpdate" funciton is not globally known for the XML I guess.

Alos, I am using the LibAddonMenu which contains a lot of code - including event register/unregister stuff. Has anyone seen any issues with this on other addons?

Yes, I did that long time ago and do not have this error anymore.
Your TopLevelWindow is so "simple", you may want get rid of the xml and create it and register the handler in Lua.
On global function less.

I've made this change to the manifest and will test with it for a while. The error is so rare it's going to be hard to know when it's fixed. Thanks all for the help!

I've just update Combat Reticle with this fix. I've been "testing" heavily for the past week and have not seen the error. So, thanks once again for the help! :)
