[Typo3-dev] Filter display of records in foreign_table based on access

[Peter Huppertz]

Hi List,

I'm using a flexform to configure my extension in the BE. The flexform 
configures a selectorbox which displays all fe_users. The problem is 
that all users are displayed, but I only want the users to be shown who 
have access to the page (the page is access restricted using the page 
header). Would it be possible to filter the display of the table using 
the allowed FE-Group? And how?
My selectorbox so far:
                    <only_user>
                        <TCEforms>
                            <label>Restrict access to</label>
                            <config>
                                <type>select</type>
                                <foreign_table>fe_users</foreign_table>
                                <size>8</size>
                            </config>
                        </TCEforms>
                    </only_user>

Thanks

Peter
