Hi, community;
I have a SWON service which contains a SPARQL query, in case the query *is*
*not
empty* the service responds with a JSON object. But in case the query *is
empty* I would like to return a non JSON response, ideally an HTTP 404 with
a payload message like "No results found."
*Is it possible to change the response type dynamically to achieve this?*
For reference, the service ui:prototype is like this:
<ui:group>
<ui:setGlobalVar ui:name="empty" ui:value="{= xsd:boolean(true) }"/>
<ui:forEach ui:resultSet="{#
...
}" ui:separator=",">
<ui:setGlobalVar ui:name="empty" ui:value="{= xsd:boolean(false) }"
/>
<swon:Object>
...
</swon:Object>
</ui:forEach>
*<ui:if ui:condition="{= ui:globalVarValue("empty") = true
}">*
<swon:Object>
*<swon:Value arg:name="Error" arg:value="No results found."/>*
</swon:Object>
</ui:if>
</ui:group>
Thanks in advance.
