This is honestly the only thing that is bugging me about this rom haha... I cannot add a damn calendar widget and I want the stock one! I have basically tried everything. I noticed apex 1.2.1 was able to have a widget and its based on the newest leak, and its the blur apps also. I overwrote basically all that I think could be associated with the "calendar storage (process com.android.calendar) has stopped unexpectedly" situation. Cleared data also, no go. I tried overwriting, blur calendar, blur calendar provider, calendar sync, google calendar sync adapter, google services framework, account and sync settings....you name it, I did it. I also added in android sync service app, and blur email engine and still a no go. I tried replacing them one by one, and also overwriting all at once. Tried with the apex files, and rubix. Nothing is a go. So it has to be something else! (obviously) but I don't know if it's a framework problem, or just a simple /system/app problem that can be easily added in or replaced. Either way, I know i'm making a big deal out of such an insignificant problem, but IMO the battery is phenomenal on this rom, the transitions are a nice treat, and it's snappy...but I use that damn calendar widget lol.....so please help!!!
