I think you're specifying the target div name in the wrong place. Instead
of:
{{=LOAD('default', 'blog_comment_show.load', args = page.id, ajax = True)}}
{{=LOAD('default', 'blog_comment_add.load', args = page.id,
target = 'comments_%s hidden' % page.id, ajax = True)}}
I think you want:
{{=LOAD('default', 'blog_comment_show.load', args = page.id,
target = 'comments_%s hidden' % page.id, ajax = True)}}
{{=LOAD('default', 'blog_comment_add.load', args = page.id, ajax = True)}}
Does that change help?
Also, in __add_2(), you might want to return response.js conditionally, only
when a new comment has actually been added -- otherwise, when the page first
loads, the blog_comment_show() component will be called/load twice (once
because of the LOAD, and once because of the response.js from the
blog_component_add() component).
If you're still having problems, I recommend creating a simplified version
of the setup just to see if you can get the basic inter-component
communication working -- then add in all the complexity and see where it
breaks down.
