@amanda.hinchman-dominguez Where can I go to see the issue you're having in your app?

there is no isBlank() on token?

@edvin to reproduce the issue, choose any image from datagrid. It will render the first grid (I should note I have up to created, so I'd stick to the first page for now)

then, click the "go back to workspace" button

"Return to Workbench"?

whoops, yeah

That seems to work.

click another image. You'll see the previous datagrid from before

But you can see the imageviews flickering because of the lack of the

cache

block there. Remember to add it 🙂

but when you click elsewhere that is not the app, and go back to it, THEN the datagrid refreshes

They all look the same to me, even when I restart the app. I don't quite understand what I'm looking at here 🙂

so you went to another grid in the workbench, clicked your computer desktop or another application, went back to the app, and it didn't render a new grid?

It renders a grid, I don't know if they should look different?

I'll see if i can produce a video

Same here

I think I see it. Inside of

init

in your

MetroTileHomepage

you're grabbing stuff off of

workbenchController.metroTile

to create your grid. This code will NEVER run again, but I think you expect it to 🙂

Code inside

init

only runs when the instance is created. A View is only ever created once in a given scope.

One way to fix it is to make

MetroTileHomepage

a

Fragment

instead of a

View

and then remove the inject line from

WorkbenchController

(Kill this:

private val metroTileHomepage: MetroTileHomepage by inject()

)

@edvin Im confused

enableWhen(user.token.isBlank())

is not compiling, why should there be a isBlank() on a Property<String>?

Then you simply find a new

MetroTileHomepage

when you need it:

workbench.replaceWith(find<MetroTileHomepage>(), null, sizeToScene = true)

@favetelinguis Because you probably should be using

StringProperty

, which has this handy thing 🙂 Sorry, forgot to mention that 🙂

@amanda.hinchman-dominguez uploaded a file:

@favetelinguis If you want to keep the

Property<String>

, you can create an observable value like this:

boringPropertyOfString.booleanBinding { it?.isBlank() ?: true }

when I wrapped cache around imageview, it made all the images disappear

@edvin I just used the UserModel i get when generating it with the intellij plugin. And it gave me a Peoperty<String>

class User: JsonModel {
    val tokenProperty = SimpleStringProperty("")
    var token by tokenProperty

    override fun updateModel(json: JsonObject) {
        with(json) {
            token = string("token")
            //error = string("error")
        }
    }

}

class UserModel : tornadofx.ItemViewModel<User>() {
    val token = bind(User::tokenProperty)
}

@favetelinguis You can actually just declare it as a

StringProperty

when you need access to those functions:

val token: StringProperty = bind(User::tokenProperty)

@edvin but in general if i want to apply any ANY String function

boringPropertyOfString.booleanBinding { it?.isBlank() ?: true }

is the way to go?

@favetelinguis That's a way of generating a boolean observable by observing one or more features of another property 🙂 It's a very handy tool, I use it a lot.

@favetelinguis Actually, if you upgrade to TornadoFX 1.7.13-SNAPSHOT, there is am

isBlank()

function even on

Property<String>

. I added it a little while back because @ron needed it 🙂

I just remembered 🙂
