QGIS search displays empty results when QGIS layer defines an expression as Display Name

[tmuguet]

Hi,

The QGIS search displays features with empty labels when QGIS layer uses an expression as Display Name:

Here's the expression I'm using in QGIS layer:

The search query to the feature info service sets with_maptip to false, which leads to feature info service / QGIS Server not outputting the maptip attribute in the response.

Fix suggestion

QgisSearch requests GetFeatureInfo with WITH_MAPTIP to false :

qwc2/utils/SearchProviders.js

Line 236 in 0d4209f

WITH_MAPTIP: false,

. It should be true.

Actually this fails when map tips use HTML.

I think we should use WITH_DISPLAY_NAME, but that doesn't seem to work: the displayName attribute is never populated in the QGIS Server response.

update: WITH_DISPLAY_NAME should work (a colleague tested it on a minimal QGIS Server sample), the problem is either in my project or in QWC.
