[TYPO3-templavoila] corrupt xml-structure after sorting of section elements

[lee perry]

hello,

i have a problem when i change the order of section elements of a FCE - 
not everytime, but with specific combinations of reordering.

for instance when i will move down two neighbouring sections and the at 
the same time move up the next section. after this reordering i've got 
the following php-warnings "Passed variable is not an array or object" 
and i can not edit this element anymore.

the reason is an empty section-element in the xml-structure of the 
element (tt_content, field "tx_templavoila_flex") after this reordering.

after deleting of the empty section-element in the xml-structure the 
editing of the element works fine again, but the problem can come back 
by the next reordering.

i'm using the latest TV-version 1.3.3.

so is this problem well-known?
and much more interesting, is there a solution?

bye and cu,
lee
