Hi all, Hi Nyall,

I am testing the new cluster renderer in QGIS master.

I want to test if all points in a cluster are of the same color (class), if not, specify an alternative color for clusters with mixed colors.

I am using the expression:

CASE WHEN @cluster_color IS NULL THEN '255,50,0' ELSE @cluster_color END

However, for some reason the "IS NULL" test is failing - the ELSE part works.

I get black colors as fall-back, but I wanted to have '255,50,0' as the fallback color.

Anyone knows why my expression fails?
