Problems with added files

[webbird]

The Library may cause several problems with page layout. Here are some I encountered:

1. If jQuery and jQuery UI are already added by other sources (hardcoded, for example), they are added again from the Library module. This definitely breaks the UI. (Tested with BlackCat CMS with jQuery and UI added by headers.inc.php of a module.)
2. Bootstrap (CSS) breaks the page layout 'cause it uses class names that are very common. Of course this could be 'fixed' by adding prefixes to the template's CSS, but if this uses another CSS framework, this is no solution.
3. The components are added to every page, even if it does not use any kF component. (WYSIWYG page, for example.)

The library itself will never load anything, it's behaviour is alway passive.
jQuery and CSS will be loaded by templates used by kitCommands. All kitCommands have parameter to disable the checking and loading of jQuery (check_jquery[false]) and CSS files (load_css[false]).
Most kitCommands will be executed within iFrames so they will never conflict with the CMS templates.

Well, it DOES in my environment...

I will try the params, but that's still unsatisfying as one will have to know if jQuery / UI is already there. It would be more comfortable to wrap them into conditional JS that checks if it's already there and loads it if needed.

A preconditional loading I have tried in the beginning - it's no good idea because the parent CMS or template may deliver jQuery from 1.x.x up to the newest release and so we stumpled into big trouble. I think its better to enable switch off loading jQuery by the kitCommands.
At the other side you can also use the kitFramework to inject any jQuery library, Bootstrap or Font-Awesome into the CMS using the parameter library[] in any kitCommand.
