TYPO3 Core

It would be very nice if the tcatree would work inside the flexforms too. IMO every tca configuration should work there as well to use the benefits of such great tools.

thrown error: #2177015888: TCA Tree configuration is invalid: "foreign_table" not set

my demo example:
-----------------------

<settings.category>
<TCEforms>
<label>LLL:EXT:news2/Resources/Private/Language/locallang.xml:flexforms_general.category</label>
<config>
<type>select</type>
<renderMode>tree</renderMode>
<treeConfig>
<parentField>parentcategory</parentField>
<appearance>
<expandAll>1</expandAll>
<showHeader>0</showHeader>
</appearance>
</treeConfig>
<foreign_table>tx_news2_domain_model_category</foreign_table>
<foreign_table_where> AND tx_news2_domain_model_category.uid > 0</foreign_table_where>
<size>5</size>
<autoSizeMax>10</autoSizeMax>
<minitems>0</minitems>
<maxitems>10</maxitems>
</config>
</TCEforms>
</settings.category>
