daniel c2172d45e4 Beware that getContent() may return null ... Before the introduction of the content handler, missing content was signified by getText() returning null instead of a string. null will work much like an empty string in most contexts, so in many places, it was not checked explcitely whether the conent was null. Now, when getContent() returns null, this often caused a fatal error, because the code would access whatever getContent() returned as an object, without checking whether it was null (because no such check was performed previously, when the content was represented as a string). This check introduces explicite checks for getContent() returning null in the most essential core classes. Change-Id: I551a90b0b67b8edc7570ca5d252ecc1de903f097		2012-11-09 19:45:12 +01:00
