Hi Adam,
you may not be surprised if I say this is hard to diagnose without more
information. You seem to be concerned about the performance and suspect
something is wrong with the template or the swa:ResultSetObjectsView
element. I see nothing wrong with the template, but I would like to
confirm that ?this is in fact pre-bound correctly - to verify just add a
line such as <div>This is {= ?this }</div> and re-run the form. If it's
not pre-bound then the query may do some extra iterations, although OTOH
you would see more results too. I assume the result rows are showing up
as you intended, but it's just slow?
As an aside, swa:ResultSetObjectsView only works in view mode, and you
would also see those values in edit mode. If you don't want this,
surround the ui:call with <ui:if ui:condition="{= swa:isViewMode()
}">...</ui:if>

Hi all,
I'm trying to customize an EVN form with data that comes from a Spin
template. Here is a simplified example of a template's body
(hw-spin:ExactCodesForContentAssetTemplate)
SELECT ?exact_code
WHERE {
?asset content_asset_schema:level_1 ?concept .
?concept hwcv_sc:exact_code ?exact_code .
}
ORDER BY (?exact_code)
/(?asset is a spin:constraint - arg)/ - This is a very basic query in
our system and it runs fast from the sparql endpoint or Composer
From within a class's ui:instanceView definition, I've added the
following:
<swa:ObjectsEnum arg:label="Codes">
<ui:call arg:asset="{= ?this }"
ui:template="hw-spin:ExactCodesForContentAssetTemplate">
<swa:ResultSetObjectsView arg:label="Exact Codes"
arg:resultSet="{= ?rs }"/>
</ui:call>
/.../
</swa:ObjectsEnum>
I actually have three such calls where each call is a rather simple
template that utilizes the same argument and should execute very
quickly. I'm pretty certain that although my aim is good the whole
business with swa:ResultSetObjectsView is not right....
Although this does seem to work, it is putting a huge load on my dev
instance. Something is spinning, even before I get to the point of
rendering a form for the instance in question. When this code is in
the form, even bringing up the taxonomy is terrible, when its out
everything zips along. So something is clearly wrong.
Thanks to anyone who has read this far!
