hi, David:
The results for what i tried for what seemed like the right
expressions to use were generally that the expression keeps evaluating
to 'null':
scripts/{{.label}}/{{value}}
shows up in my rendered page as:
scripts/null/DataSheet.doc, for example.
It seems I am not using the correct expression for getting the label
into my path.
Here is the code - this is a section that is part of a Lens view:
<div ex:role="exhibit-viewPanel" style="padding: 6px; color:white;"
ex:viewClass="Exhibit.TabularView">
....
...
<div ex:role="exhibit-lens" ex:formats="date
{ mode: short; show: date }" class="item" style="display:
none;overflow:visible;width:100%">
....
<div
id="scriptsList" class="scriptsList">
<p
class="section-title">Scripts:</p>
<ul
ex:content=".scriptURI" id="scriptsList">
<li><a
ex:href-subcontent="scripts/{{.label}}/{{value}}"
ex:content="value" class="lens-link"></a></li>
<!--other variations I tried: -->
<!-- li><a ex:href-subcontent="scripts/',.label,{{value}}"
ex:content="value" class="lens-link"></a></li -->
<!-- li><a ex:href-content="concat('scripts/',#{{.label}},value)"
ex:content="value" class="lens-link"></a></li -->
<!--
li><a ex:href-content="concat('scripts/',.label,value)"
ex:content="value" class="lens-link"></a></li -->
</ul>
</div>
...
</div>
....
</div >
And this is the data:
{
"items" : [
{
"type" : "Item",
"label" : "PUMA",
"scriptURI" : [
"DataSheet.doc",
"KnownIssues.doc",
"Demo script.doc",
"Manifest.doc"
],
"release-date" : "2009-04-20T00:00:00-04:00"
},
{
"type" : "Item",
"label" : "COUGAR",
"scriptURI" : [
"FlowDiagram.doc",
"KnownIssues.doc",
"Architecture.doc",
"CaseStudy.doc"
],
"release-date" : "2009-04-20T00:00:00-04:00"
},
[etc....]
]
So that in the end, i'd like the lens to render this for each item,
dynamically:
/scripts/PUMA/DataSheet.doc
/scripts/PUMA/KnownIssues.doc
/scripts/PUMA/Manifest.doc;
and for label=COUGAR:
/scripts/COUGAR/CaseStudy.doc
/scripts/COUGAR/FlowDiagram.doc
etc.
John:
the problem is that I dont know these label name values beforehand,
even if I wanted to hardcode them in the function you provided.
The URL to this exhibit is internal to my company, so I am sorry I
cannot share that.
I hope this is sufficient info, sorry I was unclear.
best,
-k
