[Qgis-user] QGIS 2.16 - Rule based labelling

[Fuenfer-Koenigstein.Benjamin at swm.de]

Hi Chris,

yes, now I can confirm. I forgot to test the expression builder. The issue occurs, as you said, only when I change the rule in the 'expression string builder' window. A workaround might be to create the expression in 'expression string builder' window, copy it and paste it into the 'filter' text field which retains the text. Or you could change the expression in expression builder, OK, type a blank and delete it again in 'edit rule' window, then the expression is retained. Anyway, I think it would be good to report the bug on http://hub.qgis.org/issues.

Hi Benjamin

My process is as follows...

Using a point dataset from PostGIS, and the rule based labelling for Labels.

My rule says "CLASSIFICA" = 'Woodland Or Forest' AND "FONTHEIGHT" = 'Small', with this I also have a scale range included.

When I try to change this (for example to "FONTHEIGHT" = 'Medium'), I click on the browse button next to 'Test', I then manually alter the text within my expression from 'Small' to 'Medium'.

I OK this - back at the 'Edit rule window', I do see that the text has changed to 'Medium', I then click OK but back at my rule based labelling screen the text still says 'Small'.

If I decide to change the expression from the 'Edit rule' window and not open the expression, it does retain the change, so there looks to be an issue (from my set up anyway) where it is not storing any changes within the expression window.

I am using QGIS 2.16.1.

Thanks, Chris

Hi Chris,

cannot confirm this behavior, my expressions are retained, both when I type them directly in the rule-list and when I type them in the "edit rule" window. I'm using 2.16.2. Can you give more details, e.g. what does your rule look like, what buttons do you use exactly, so I can try exactly the way you do? Did you try the "Test" button in edit rule window to find out if your expression works/makes sense?

Hi

I am using the rule based labelling in QGIS 2.16 and am noticing that when I go into a rule then choose the filter and put my expression in, when confirming this it does not retain my expression.

Is this a known issue or perhaps something wrong with the workflow I am using?

Thanks, Chris
