SharePoint Framework documentation propertyPaneConfiguration

Question

I'm finally getting around to looking at the SharePoint Framework again (working on it in my few spare cycles when I don't have client work). The documentation says "Replace the propertyPaneConfiguration method with the code below which adds the new property pane fields and maps them to their respective typed objects." I replaced the code as instructed and I get an error "Cannot find name IPropertyPaneConfiguration" and "Return type of public property getter from exported class has or is using private name IPropertyPaneConfiguration" on the line:

protected get propertyPaneConfiguration(): IPropertyPaneConfiguration {

Should that read

protected get propertyPaneSettings(): IPropertyPaneSettings {

Answer 1

Your code should be

protected get propertyPaneSettings(): IPropertyPaneSettings

Looks like the documentation is incorrect. I'll log a bug to fix it.
