<p>Hi all,</p>
<p>At my new work place we are running a 2.x QGIS server which in two projects behaves very strange: sometimes colors display in the color we expected, sometimes really light. Then my colleagues discovered that more than rules share the same UUID identifier, because the QGS files have been copy pasted into a anew project and then aggregated again into the same single project.</p>
<p>Not knowing about the internals of QGIS server 2x (and 3x) I wonder if this something we need to avoid? Are the UUID identifiers of a symbology rule relevant and absolutely need to be unique? Do we have to avoid such id clashes?</p>
<p>The "human readable" nature of qgs/qml files naturally seduce people to copy / paste and mix project stuff together in text editors ...</p>
<p>Thank you for your feedback on this topic.</p>
<p>Andreas</p>
