[Typo3] Flexible Content: Data Structure ERROR: No Source Value

[Dmitry Dulepov]

Hi!

You cannot set FCE as a page template (provided that you saved it
correctly). FCE are *content* elements, not page templates.

To insert FCE you need to create normal text element on the page first
and then change value in the "Type" combobox to "Flexible content". Than
page will refresh and "Data structure" will appear. If you do not see
name of your DS at this point, it means you saved your FCE as a page
template, not as FCE (this is wrong, resave it as FCE in TV control
center)! Then you need to select DS for your FCE. Press "Save" (it is
mandatory to save at this point!).

Template object name should appear in the "Template object" combobox. If
it does not, than something is really wrong.

I attach a picture to show how it should look like.

Dmitry.
