Description

The fill_colors argument no longer seems to have an affect on how vectors are displayed. It seems to only display as a blue color.

What I Did

Local command: solara run aqua_app/pages --host=0.0.0.0 --log-level-uvicorn=warning --workers=10 --access-log --pdb

I added the fill_colors argument to the add_geojson() command (as in this example, specifically the "Add a GeoJSON" section) and the fill colors of the vectors did not change or randomize. The example site actually shows the same results.

import leafmap
from reacton import component as component
import solara


class Map(leafmap.Map):
    """
    This is the map which will be displayed in the solara webapp
    """

    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        self.add_layer_manager(opened=False)
        self.add_geojson(
            "/Users/jmarokhovsky/path/to/vector/country_vectors.json",
            layer_name="Simple World",
            fill_colors=["red", "yellow", "green", "orange"],
            zoom_to_layer=True,
        )


zoom = solara.reactive(7)
center = solara.reactive((20, 30))


@component
def Page():
    css = """
        .v-application .primary {
          background-color: #c00 !important;
        }
    """
    solara.Style(css)
    with solara.Column(style={"min_width": "600px", "z-index": "2"}):
        Map.element(  # type: ignore
            zoom=zoom.value,
            on_zoom=zoom.set,
            center=center.value,
            on_center=center.set,
            scroll_wheel_zoom=True,
            toolbar_ctrl=False,
            draw_control=True,
        )

Thanks for reporting. This bug has been fixed and should be available in v0.35.10.

[jmarokhovsky]

Confirmed, I'm seeing colors in v0.35.10:

Thanks for fixing this!
