BUG- Map not loading in multi-page application

FlorianJacta commented 1 year ago

Description A strange behavior has appeared in Taipy 2.1 (not present in Taipy 2.0). Loading a map on a page doesn't work sometimes, markers are not displayed. It seems to happen when the application is multi-page and when the user goes from one page to the other.

How to reproduce You should land on the chart page. Going from one page to another, no markers are present on the map, even if marker texts can be found on the map. Refreshing the page will show the markers again.

from taipy.gui import Gui 

data = {"number":[50,78,95,78,12,46],
        "size":[50,78,95,63,45,23],
        "lat":[39.83049768,49.83049768,59.83049768,69.83049768,35.83049768,33.83049768],
        "lon":[39.83049768,49.83049768,59.83049768,69.83049768,35.83049768,33.83049768],}

marker_map = {"color":"number", "size": "size"}
layout_map = {"mapbox": { "style": "open-street-map"}}

map = "<|{data}|chart|type=scattermapbox|lat=lat|lon=lon|marker={marker_map}|layout={layout_map}|mode=markers|height=800px|>"

pages = {"/":"<|navbar|>",
        "chart":"# Chart",
         "map":map}

Gui(pages=pages).run()

Expected behavior The map should always show the markers directly going from one page to the other.
