[TYPO3-rte] Link transformation problem

[Christian Futterlieb]

Hi list!

I have a strange problem with the transformations from RTE to DB. I 
found many infos in the web, but I could not solve it.

I have an extension with a DB table containing a field 'text', which 
should be RTE-enabled. In $TCA the column looks like this:

'text' => array(
     'exclude' => 1,
     'label' => 'LLL:EXT:bubbles/locallang_db.xml:tca_bubble_text',
     'config' => array(
         'type' => 'text',
         'cols' => '48',
         'rows' => '5',
         'softref' => 'typolink_tag,images,email[subst],url',
     ),
     'defaultExtras' => 'richtext:rte_transform[mode=ts_css]',
),

When I save a text into this filed, the links will be absolute links 
like <a href="http://typo3test.local/index.php?id=1"> instead of <link 2>.

I'm working on a plain TYPO3 installation (6.1.3) with nothing 
configured (no typoscript, no TSConfig). The same happens with TYPO3 6.0.8.

The links in tt_content.bodytext are saved correctly.

Can anyone point me to the solution of this mind-boggling problem?

Thanks, Christian
