MapView 0.20.3

hybridPa · June 9, 2016, 11:06pm

Hello everyone, thanks to fuse team for your hard work. I love fuse very much and using it for my small project, as soon as I can, I will definitely share it with you and community

In previews version I had no problems with GeoLocation, but the final version 0.20.3 making app crash. I have no problems with getting object and data from GeoLocation module. However, problem accures when I use MapView. Am I the only one having this trouble?

Thanks in advance

At a minimum the MapView should be inside a <NativeViewHost>. Can you try that as well?

hybridPa · June 10, 2016, 11:22am

At first it was working great, I mean before 0.20. I was using in the .

I am on Windows 10. If thats helps somehow.

Have a good day fuse team:)

same error here:

    <DockPanel ux:Class="MapPage">
        <Router ux:Dependency="router" />
        <JavaScript File="map.js" />

        <Panel>
            <NativeViewHost>
                <MapView Latitude="41.5667" Longitude="2.0167"> 
                    <Each Items="{uxMapPageMapMarkers}">
                        <MapMarker Latitude="{lat}" Longitude="{lng}" Label="{name}" />
                    </Each>
                </MapView>
            </NativeViewHost>
       </Panel>
   </DockPanel>

i was getting app crashes (no errors before updating to 0.20) with this code:

        <MapView Latitude="{uxMapPageLat}" Longitude="{uxMapPageLng}" ShowMyLocation="{uxMapPageShowOwnLocation}" Zoom="{uxMapPageZoom}" ShowMyLocationButton="true">

so i thought the problem was some of the parameters but i keep getting the app crash even hardcoding the lat - lng (first example)

Hey guys, the MapView has been refactored for stability and general smartness and this should no longer occur as of the next release. Sorry for the inconvenience here, and thanks for reporting

hybridPa · June 13, 2016, 8:06pm

Hello, thank you fuse team And may I ask if this update will be available this week?

Bent · June 13, 2016, 8:08pm

The next release (including this fix) is scheduled for next week.

hybridPa · June 13, 2016, 8:11pm
