<p>Hi,</p>
<p>In a model I aggregate values to a single feature. Then I would like to extract a specific aggregated attribute to a string so I can use it as the input parameter of another algorithm.</p>
<p>I fail to find a way to do that. Aggregation works fine, string concatenation as well, but I fail to find a way to extract an attribute of a single feature to a string.</p>
<p>Any ideas?</p>
<p>I'm on QGIS 3.10, but if necessary I could also use a newer QGIS version.</p>
<p>Thanks,</p>
<p>Andreas</p>
