Description

If I go into data defined properties for a symbol, and create an expression which contains only a single numeric value, eg "10", then this expression is immediately lost after clicking the OK button. A workaround is entering an expression such as "10+0", which is accepted by QGIS and retained.

I realise it's probably not that common to have a single constant value as an expression, but it should still be possible to do this.

  • Status changed from Open to Closed

Still true on the latest master, while another issue (the one that stripped "(" from the data defined expressions) seems solved.

Moreover the workaround 10+0 does not works on master.

Merging with #9783
