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

[Dmitry Dulepov]

Btw,

  Data Structure ERROR: No source value in fieldname "tx_templavoila_ds"

is really typical message when you just created a new page. This have
nothing to do with FCE, it talks about *page* template. Is it possible
that you want to experiment with FCE but looking in the wrong place?
