Regression with expressions in Composer

[qgib]

Author Name: Pedro Venâncio (Pedro Venâncio)
Original Redmine Issue: 21471
Affected QGIS version: 3.4.5
Redmine category:map_composer/printing

---

I updated QGIS 3.4.5, 3.6.0 and 3.7.0 today to 3.4.5-3 (code revision 8ba90fc), 3.6.0-4 (code revision ec30c48) and 3.7.0-4 (code revision 34a0650) with OSGeo4W, and the labels with expressions are not rendered as expected, when are used more than one line.

For instance,

[% CASE WHEN month($now) = 3 THEN 'March' END || ' ' || year($now) %]

renders ok

March 2019

but

[% 
    CASE WHEN month($now) = 3 THEN 'March' END || ' ' || year($now) 
%]

renders

[% 
    CASE WHEN month($now) = 3 THEN 'March' END || ' ' || year($now) 
%]

I'm sure this is a regression, because it was working fine before today's update. Last week this was working fine.

Hi Nyall,

Thank you very much for the fix!

But this also needs to be backported to release-3_4 (LTR).

Thanks!

Hi Pedro, I think we can keep this closed as the bug is fixed, for heads up about backporting I think is better to leave messages in the PR on GitHub.
