[TYPO3-mvc] two objects, I see only one

Dear Franz

thanks so much for your reply.
Indeed, I start to be able to do something.
A few comments, maybe they could be useful to some other newbie.

Yes, of course. I was just trying a basic example. Anyway, I have
modified it. Now I have:

Object: Author  (entity); Properties: Name and Comment; relation Book
m:n to Book.
Object: Book (entity); Properties: Title and Comment; (no relation)

then something like the following works pretty well:

Resources/Private/Templates/Author/List.html
<f:for each="{authors}" as="author">
	... {author.name} ...
<f:for each="{author.book}" as="book">  
... {book.title} ...
</f:for>
</f:for>

Very Nice!!

Ext Builder does not provide a flexForm (or at least I don't see that it
does). Looking at
https://svn.typo3.org/TYPO3v4/Extensions/ballroom_dancing/ 
(not on TER? not at http://git.typo3.org/?), I hacked their
flexform .xml file. It seems I need to insert a few lines within
ext_table.php too (do I?)

$pluginSignature = str_replace('_','',$_EXTKEY) . '_' . <myext>;
$TCA['tt_content']['types']['list']['subtypes_addlist'][$pluginSignature] = 'pi_flexform';
t3lib_extMgm::addPiFlexFormValue($pluginSignature, 'FILE:EXT:' .
$_EXTKEY . '/Configuration/FlexForms/flexform_' .<myext>. '.xml');

Indeed Ext Builder provides these lines, you just need to uncomment
them.

Ext Builder does the latter. For the former TCA issue, I need to look at
how to configure the foreign_selector, don't I?
