[TYPO3-english] startingpoint custom extensions TYPO3 4.5

[Adrian Mot]

Hello everybody,

I have upgraded from 4.4 to 4.5 and now the Startingpoint (Pages) field 
from the custom extensions is missing.

I thought first that these were disabled by default in 4.5, so I have 
changed the ext_tables.php in the ext folder:
$TCA['tt_content']['types']['list']['subtypes_addlist'][$_EXTKEY.'_pi1']='pi_flexform,pages';

The result was that the Startingpoint was added below the flexform (as 
it was in 4.4), but whenever I try to add a page there (either via popup 
or autocomplete) I receive a JS alert:

Formfields missing:
  fName: [object NodeList]
  fName_list:[object NodeList]
  type:undefined
  fName:data[tt_content][44][pages]

I also tried a fresh 4.5 setup, and then adding an extension to test it, 
but the same result comes up.

I could do it the easy way just to implement a new flexform field for 
this purpose, but I am really keen on knowing what am I doing wrong.

Do you have any idea about the above issue?

Thanks,
Adrian
