Sample project does not save value in custom page about arcgis-pro-metadata-toolkit HOT 2 OPEN

I had trouble with that control also. I thought a colleague was able to get it to work, but I didn't have a chance to figure out what they did differently to allow that. In the meantime, check out the instructions here in the wiki: https://github.com/Esri/arcgis-pro-metadata-toolkit/wiki/Create-a-custom-page, which direct you to remove the default control and add one that actually works.

from arcgis-pro-metadata-toolkit.

It appears that the default control is missing the binding to the XML. The example on the create-a-custom-page page does include that binding.

<TextBox Style="{DynamicResource EditorTextBoxStyle}"
                Text="{Binding XPath=/metadata/custom/myData/trackingStatus, Mode=TwoWay}"/>

also note: the sample on the create-a-custom page page binds the track status to //status

but the XmlDataProvider puts the value in /metadata/custom/myData/trackingStatus
