Are you looking to treat this situation differently or just to prevent the error from being thrown?
I would simply wrap the webuisupport code into an <attempt> block to achieve the latter...
cike,
Try something like this in your code.
<#assign labelSelected = webuisupport.path.parameters.name.get ("label-name","") />
<#if labelSelected?? && labelSelected?has_content>
Your selected label ${labelSelected.text}
<!-- and then execute the query here with ${labelSelected.text} -->
</#if>
I already something similar to this. But it's still the webuisupport line which fails. So, I my code never reaches the if-clause.
I double-check this to. The object is used in our components only. Well, as I already said, for other blog nodes, where content was created, everything works as expected.
Maybe this a limitation by the context object webuisupport, which doesn't occur in default cases. Mostly labels will only be rendered if they were used at least one time.
In my case the blog page with label filter is accessible all the time, even if there is no content.
