the block is attached, planning on releasing open source in the marketplace. Its basically a mod ofhttp://alexgorbatchev.com/SyntaxHighlighter/... to allow easy use in concrete5.

I think this might be a bug with Concrete5. I have run into similar problems in the past when using custom templates in packages -- something about the c5 loader code doesn't look in the packages directory for related assets. If you move the block out of the package and into your site's /blocks/ directory and install it from there (after un-installing the package and temporarily removing that from the /packages/ directory), you can see if it works that way -- and if so then you know it's a problem specifically with the way packages work.

See:

Unfortunately I know of no workaround -- all I can think of is manually inserting the appropriate css file in the block controller's on_page_view() method. Not sure how you can get the currently-selected custom template in code though.

ok thanks. I couldn't get it working in the /blocks directory either- but maybe thats cause somethings wrong with my code. I don't know how to get selected custom template either though.

That's weird -- there is no code for custom templates -- either the file exists or it doesn't.

Did you uninstall the package and remove the package folder from your site before trying it in the blocks?

yeah, I did. Not sure whats causing it. I am on the latest beta though, ill try on a stable version
