I see. One option might be to include code in your "component.load" view
that makes use of the component's response.files, just like the code in
web2py_ajax.html. For example, in "component.load" include:
{{
for _k,_file in enumerate(response.files or []):
if _file in response.files[:_k]:
continue
_file0=_file.lower().split('?')[0]
if _file0.endswith('.css'):}}
<link href="{{=_file}}" rel="stylesheet" type="text/css" />{{
elif _file0.endswith('.js'):}}
<script src="{{=_file}}" type="text/javascript"></script>{{
pass
pass
}}
The above will link your component's css and js files in the component HTML,
which will be inserted in your 'index' page (give that you have ajax=False).
If you don't want to repeat that code in all your .load views, you can
probably create a function in a model file or module and just call the
function from your views.
