Thanks for the quick response.

Nope, no custom Controllers. i was thinking that it was too simple to need
them.

Yeah, have done so. The link works fine without the ajax additions.

I see no errors in the console. When I don't use push-state in the <a>, it
shows a jquery.js script that is text/javascript type that supposedly is
working fine. When I do include push states, it acts as if it were
<a></name></a>.
Wait I found an error for the push state that was getting thrown up before
I could notice it.
Uncaught TypeError: converting circular structure to JSON.
And then it loads the show page as a new URL. I had the debugger switch to
pause on exception caught and where it stopped was:
/**
* History.cloneObject(obj)
* Clones a object and eliminate all references to the original contexts
* @param {Object} obj
* @return {Object}
*/
History.cloneObject = function(obj) {
var hash,newObj;
if ( obj ) {
hash = JSON.stringify(obj);
newObj = JSON.parse(hash);
}
else {
newObj = {};
}
return newObj;
};
within the history_core.js.

Let me post what the server shows. Without the push-state:

I think I do. i added it to the gem file and did a bundle install and now
it shows up on the gem list. And then I added the line to the
application.js as described in the Readme you posted in the manual. And
history.js loads from the assets as the page is loaded.

I posted the server log above but I see no :this_id =", but instead just an
"id="main-panel", which is what I am calling the part. That could also be
the problem. I define the part in page tag I defined to create the aside.
<def tag="systems-show">
<page>
<content: replace>
<section-group class="page-content">
<aside param="aside1"/>
<section param="content"><do part="main-panel"></do></section>
</section-group>
</content:>
</page>
</def>
Question. Should this work both ways, with and without the push-state? If
so, what is the difference between the push state and just using the ajax
calls on the link function alone?
Thanks a lot for your help. I seem to have trouble finding enough sample
code of Hobo to figure out certain things.
