[TYPO3-dev] extending t3lib_pageSelect getMultipleGroupsWhereClause

[Federico Bernardin]

Hi guys,
I create an extension that extends the access control for pages and contents adding another field (so my pages have fe_groups access and the new field that using a list control).
My problem is in the link creation control (tslib_content pageLink) to protected page with new field. If I create a link in a protected page with fe_groups forward to another page protected with new field, my authentication doesn't work.
The function that controls the access to page is getMultipleGroupsWhereClause inside t3lib_pageSelect class, and this function isn't extensible except with xclassing.

I think should be insert an hook inside that function.

Cheers
Federico
