@carlw You need to specify jvmTarget 1.8 in your gradle build file.

compileKotlin { kotlinOptions.jvmTarget= "1.8" }

thx...i was copying from a 1.5 example that predates the 1.6 cutoff

Ah 🙂

what's the binding expression for a command? i'm directly invoking the execute() from the action

When you have a Command, instead of creating an action handler on a button, you simply bind the command to the button, and the framework will execute the command when you click the button. So this:

@User uploaded a file: Untitled

Should be written like this:

@User uploaded a file: Untitled

This is how you defined the del command now:

@User uploaded a file: Untitled

Let me rewrite that.

textfield doesn't have a command property?

@User uploaded a file: Untitled

@carlw I can add it, hang on.

getting a singleAssign() error "value has not been assigned yet". do i need to use lateinit?

Where?

I just committed Commanding support for

TextField

.

i have the lv as a singleAssign but the new syntax for commandParameter is throwing the error on the lv.selectedItems

I see the problem. The ListView has not been assigned when we bind the delete command, so it's not accessible yet. I will show you a better way to deal with this.

ok. previously the assignment was in the body of a function

@User uploaded a file: Untitled

I see there is room for improvements though.

This works, but the UI to delete items is a bit awkward since each ListView cell has a textfield spanning the whole thing. To select one for deletion you have to click outside the textfield but inside the cell.

By the way, instead of

addListener

which takes three arguments, you can use `onChange`:

@User uploaded a file: Untitled

You should probably use cellFormat instead of cellCache as well. I will try to make some optimizations to it, so it is just as cheap as cellFormat, but without the memory issues.

@User uploaded a file: Untitled

@edvin i'm getting a weird error in a different place after upgrading to 1.7.5-SNAPSHOT
