[Typo3] content change from text -> text/w. image: content disappers

[stowoda]

Hi,
the following TS works fine, as long as my content is type "text". If I 
change the content type to "text w/image" (in list/page/edit 
pagecontent) it disappears.
using Typo3.8.0 + PHP 5.0.5

Here comes the TS:

***********************************
# Default PAGE object:
page = PAGE
page.typeNum = 0

page.20 = CONTENT
page.20 {
   table = tt_content
   select {
     pidInList = this
     orderBy = sorting
   }
}

tt_content = CASE
tt_content.key.field = CType

tt_content.header = COA
tt_content.header {
   1 = TEXT
   1.field = header
   1.wrap = {$cHeaderWrap}
   1.space = 3 | 2
}

tt_content.text < tt_content.header
tt_content.text {
   3 = TEXT
   3.field = bodytext
   3.fontTag = {$cBodyTextWrap}
   3.br = 1
}

***********************************
Any idea?
