PoiCollection in multiple categories - Frontend behaviour

[twaurisch]

If a PoiCollection is assigned to more than one category the frontend behaviour acts not like expected.

Example:
Poi1 is assigned to CatA and CatB, both categories are selected and Poi1 is displayed in the Frontend. If unselecting CatA Poi1 disappears on the map although CatB is still active and Poi1 assigned to it.

Poi1 should only disappear if all assigned categories are not selected.

Example: 3 Pois and 2 Categories

• Poi1 => [CatA, CatB]
• Poi2 => [CatA]
• Poi3 => [CatB]

Result of the database query

in PoiCollectionRepository->addConstraintForCategories(...)

• Rec1 = Poi1 => [CatA, CatB]
• Rec2 = Poi1 => [CatA, CatB]
• Rec3 = Poi2 => [CatA]
• Rec4 = Poi3 => [CatB]

Categorized marker array

in OpenStreetMaps2.js -> OpenStreetMaps2.prototype.createPointByCollectionType

• Cat A => [Rec1, Rec2, Rec3]
• CatB => [Rec1, Rec2, Rec4]

The four records from the database arte the result of a LEFT JOIN in the mentioned method. With this concept each record represents a poi for one category. So each record (_leaflet_id) should be in only one category after 'createPointByCollectionType':

• Cat A => [Rec1, Rec3]
• CatB => [Rec2, Rec4]

I created a workaround in the OpenStreetMaps2.js file:

let categorizedLeafletIds = [];
...
if (categorizedLeafletIds.indexOf(marker._leaflet_id) < 0) {
    this.categorizedMarkers[categoryUid].push(marker);
    categorizedLeafletIds.push(marker._leaflet_id);
}
