[TYPO3-dev] Template issues

[Osipov Dan]

Hey everyone,
 
I am trying to apply templates to my extensions, and running into problem. I am using the wiki page about the HTML markers, and using the modified code from there.
 
So I've filled my HTML file with tags like this:
 
<!-- ###MARKER1### begin -->Sample content that has to be replaced by extension output<!-- ###MARKER1### end -->
 
Sometimes the entire line is replaced by the correct output, but more often just the text ###MARKER1### is replaced, so the output is commented out in HTML.
 
Does anyone have a good rule for when to use which tag, and how to avoid this problem?
 
FYI, I also ran into this problem with a default install of 'comments' extension, where the CAPTCHA code was placed onto the page, but commented out. I think it wasn't the latest version though.
 
Thanks!
Dan
