• Type: Bug
• Status: Closed
• Resolution: Fixed
• Affects Version/s: 7.0.X, 7.1.X, 7.2.X, Master
• Fix Version/s: 7.3.0 CE GA1, 7.3.10 DXP GA1, Master
• Component/s: ~[Archived] WCM
• Labels: None
• Fix Priority: 3
• Git Pull Request: https://github.com/brianchandotcom/liferay-portal/pull/80437

Reproduction steps:

1. Start latest master bundle
2. Create a structure named "struct1"
3. Add a Separator to the structure
4. Add a Geolocation field embedded into the Separator
5. Add a template to "struct1"
6. Click on the Geolocation field on the left, and its pattern will be inserted into the template
7. Save it and create a web content from "struct1"
8. Select a location for the GeoLocation field, save the content
9. Preview the content (eye icon in the "Default Template" section)

Actual result: the map is not shown, you can only see an empty <div> element, and the following javascript error:

Uncaught Error: Map container not found.
    at e._initContainer (leaflet.js:5)
    at e.initialize (leaflet.js:5)
    at new e (leaflet.js:5)
    at Object.t.map (leaflet.js:5)
    at MapOpenStreetMap._createMap (?
...

Expected: the map with the selected location should be shown

This is a part of the generated FTL template:

<@liferay_map["map-display"]
	geolocation=true
	latitude=latitude
	longitude=longitude
	name="Text4vud.Geolocation77ue${randomizer.nextInt()}"
/>

When the name attribute doesn't contain "." character, it should look like this:

<@liferay_map["map-display"]
	geolocation=true
	latitude=latitude
	longitude=longitude
	name="Text4vud_Geolocation77ue${randomizer.nextInt()}"
/>
