Hi! I am using moko livedata (version 0.10.1) with databinding in layout.xml. Can I ask how to refer to a LiveData as shown in the screenshots below?

I tried android:text="viewModel.station.ld().name" and android:text="viewModel.station.ld.name" . The initial value can be read correctly, but it never updates.

Despite of the IDE highlighting, try to compile this 🙂

I came across this issue resently and this compiles fine, I think the reason is that there is also LiveData in common code that has no ld() method

updates will work only if databinding have setted lifecycle.

in moko-mvvm it's done here - https://github.com/icerockdev/moko-mvvm/blob/master/mvvm-databinding/src/main/kotlin/dev/icerock/moko/mvvm/MvvmActivity.kt#L32

Thanks for your explanation! I did more experiment and found .ld works fine, while .ld() does not.
