Indexed search displays html and js-code typo3

I've upgraded from 4.2 to 4.5 in single upgrades (4.2->4.3 etc.). After the开发者_JS百科 final upgrade, the indexed search displays the html and js code of some content blocks in the search results. Not all though. I can't find a pattern for that. I moved the HTML block to the bottom, in case it now simply displays the top most block, I emptied all tables that start with index_ to make sure it renders the index new, i emptied my browser's cache, it still displays html and js code.

I compared it to a node, that is displayed correctly as a result, the html block is top most, the code is the same, just two pictures were added for a image slider, Access and Appearance have the same settings.

Any idea what's causing that behavior? someone experienced the same thing?

Thanks for your answer and sorry for the trouble.. (just to make this complete, yes, HTML was valid.)

I did not quite found out why this search-thing occurs, but I managed to find a workaround by extracting the JS in a seperate .js-file, and call it within the script-tags. I expected it to don't display any teaser at all, but it displayed to real content instead. No idea why that happened, but I can suppress it like that. Maybe that will help somebody else too..
