[TYPO3-dev] double headers

[Bas van der Togt]

hello list,

When editing a page title in the backend all the headers are printed 
twice on the frontend. After a clear all cache in the backend, all 
headers are printed right again.

This only happens when using this piece of typoscript:

temp.stdheader < lib.stdheader
lib.stdheader >

lib.stdheader = CASE
lib.stdheader {
	key.field = colPos
	1 < temp.stdheader
	2 < temp.stdheader
	3 < temp.stdheader
	default < temp.stdheader
}

// default
lib.stdheader.default.10.2.fontTag = <h2><span>|</span></h2>
lib.stdheader.default.10.3.fontTag = <h3><span>|</span></h3>

// left
lib.stdheader.1.10.1.fontTag = |

// right
lib.stdheader.2.10.2.fontTag = <h3><span>|</span></h3>

// border
lib.stdheader.3.10.1.fontTag = |

I was wondering if this is a bug, or i did something wrong in typoscript.

Best regards,
Bas
