[FLOW3-general] Blog Package error

[Gideon So]

Hi All,

	I am new to flow3. This is may be a dumb question but please kindly
bear with me.

	I cloned the Blog package with:

	git clone git://git.typo3.org/FLOW3/Packages/Blog.git Blog

	git submodule init

	git submodule update

	Then I put mysql stuuf in FLOW3/Configuration/Setting.yaml

	I pointed my browser to it. There is a error:

	Uncaught exception #1296143788 in line 40 of
/path/to/installation/Blog/Data/Temporary/Production/Cache/Code/FLOW3_Object_Classes/F3_FLOW3_Persistence_Doctrine_Mapping_ClassMetadataFactory_Original.php:
Missing required constructor argument $entityName in class
F3\FLOW3\Persistence\Doctrine\Mapping\ClassMetadata. Note that
constructor injection is only support for objects of scope singleton
(and this is not a singleton) – for other scopes you must pass each
required argument to the constructor yourself. [logged in
F3\FLOW3\Persistence\Doctrine\Mapping\ClassMetadata::__construct()]

	Then I switch to development mode. It shows a error like this:

	#1: Notice: Undefined index: f3_typo3_user in
/home/web/testserver/Blog/Packages/Framework/FLOW3/Resources/PHP/Doctrine/ORM/Persisters/AbstractEntityInheritancePersister.php
line 76

	What should I do.
