• Does it make sense to test ui components seperately?

  - by Bless Yahu

  I'm working on a webform that has about 15 user controls, separated by context (comments, locations, members/leaders, etc).   If each control can render individually (using real or test data), does it make sense to have a seperate "functional" test page to test them in isolation or is there a better way?

  Hi, I'm looking at market stats here for sdk distribution: http://developer.android.com/resources/dashboard/platform-versions.html saying that 31% of marketplace users are still running 1.5.

Just curious because I'd like to use th setView() method introduced in 1.6 for TabSpec, but not if so many people are still using 1.5, I might have to roll my own control, Thanks

• Why does Application_Deactivated not get called on a pivot page?

  - by willmel

  For my Windows Phone 7 app, I have a main panorama page which opens up into a pivot control. The main panorama page correctly calls Activated/Deactivated, and restores correctly. But after visiting the pivot page, pressing the Windows key doesn't call Deactivated. When the app is relaunched with the back button, it goes right to how the page looked before tombstoning, but Activated is not called, and the page is not usable, and the back key doesn't work. Has anyone else experienced this problem before?
