Hello.
I have patched Exhibit3 a little bit, according to our discussions.
I now load hierarchical JSON structures in the database correctly (I hope :)
cf http://search.datao.net/test/index2.html
The trick is to call _loadItem recursively.
Unfortunately, the HTML display is still wrong in my page.
I think that my lens definitions are wrong.
For the moment, I wrote something like this:
<div data-ex-role="viewPanel">
<div data-ex-role="view"
data-ex-view-class="Thumbnail"
data-ex-show-all="true"
data-ex-paginate="true"
>
<table data-ex-role="lens" class="itemThumbnail" style="display:
none;" data-ex-item-types="x">
<tr>
<td style="vertial-align:bottom" class="itemThumbnail-thumbnailContainer">
<div style="position: relative">
<div data-ex-content=".a"></div>
</div>
</td>
</tr>
</table>
<div data-ex-role="lens" data-ex-item-types="a">
<span data-ex-content=".label"></span>
</div>
</div>
</div>
The first lens displays the outer JSON object of my data.
Inside that lens, the <div data-ex-content=".a"></div> is supposed to
delegate the display of the inner JSON object (of type a, and
available from the outer JSON object via the path .a) to a second
lens, dedicated to objects of type "a".
But that delegation does not happen, it seems.
Can anyone help me debug that part of my example?
