@amanda.hinchman-dominguez OK. To give you some perspective, consider this: Some other thread could have yanked out the value between where you added it and when you accessed it again.

@amanda.hinchman-dominguez uploaded a file: Untitled

On top of that, the compiler doesn't have intricate knowledge about how hashmaps works, it's just another class with accessors.

I thought that containing the value would be enough, but I could add another qualifier for

::isInitialized

The thread issue is there, and on top of that, a function called

contains

in an arbitrary class, with an arbitrary parameter does not mean anything special to the compiler 🙂

That makes sense. I originally tried making

hashMap = HashMap<String, moduleBuilder?>

but I guess the compiler can't recognize that beforehand either

You could write it like this:

@edvin uploaded a file: Untitled

That would skip assigning to

inFlightTileProperties

unless there is a value in the hashmap for that property. I don't know if it's important in your use case though.

What should happen if there is no value in the map for that key?

That works perfectly with the rest of the functions -

right now, there's detection in some functions to make sure that inFlightTileProperties has been initialized

no inflight tile is created

OK 🙂

@amanda.hinchman-dominguez Cool 🙂

This SO question brought up need for that extension function we added a while back @ron 🙂

Ohh that is nice! I needed to restrict input and used a textformatter. This is much nicer.

How does that differ from

stripNonInteger()

?

Oh, I think I see. Looks like it's performing the filter on the input event, rather than waiting until it's already landed in the

textProperty

of the view?

@edvin can you only use ItemViewModels for binding to Forms? I'd like information to eventually translate toJSON, like the JsonModels I'm working with

@amanda.hinchman-dominguez you can definitely bind an itemviewmodel to a form. Just pass the property to the textfield or other control you would like to bind to present to the user

Another probably frustrating bug squashed: https://github.com/edvin/tornadofx/issues/622

@Carlton Whitehead To be able to paste text with whitespace you'd need to use

stripNonInteger

. The solution I posted will not allow the change unless it matches the predicate.

@amanda.hinchman-dominguez You can bind any property to form elements, in fact form elements are no different from input elements of any kind. However, if you want to add validation and decoration you need to bind to properties in a ViewModel. That ViewModel doesn't have to extend ItemViewModel though.

I'm thinking we should release 1.7.15 now, but I'd like some imput on the breaking change concerning the

readonlyColumn

builder for TableView. The problem was that the

column

builder for binding against val's that were not JavaFX properties (for example fields in data classes) would shadow the

column

builder for observable properties, making it impossible to supply an op parameter to those. The only workaround I could find was to rename the

column

builder that targets immutable values to

readonlyColumn

. This will break for many I believe, especially you @thomasnield. Can anybody think of a better way to deal with this? I should have detected this when we introduced the column builder for immutable properties, but unfortunately this slipped through.

@edvin @bkenn wow this is embarrassing but I completely misphrased my question - I know that you can easily bind

ItemViewModels

to forms - can you bind

JsonModels

to Forms as easily? I tried earlier but was unsuccessful.

@edvin I see your point about validation

I'd like to be able to do that, but the use case would have to essentially cause me to me 2 version of a model due to model types

@amanda.hinchman-dominguez JsonModel is just an interface that defines some functions (

updateModel

and

toJSON

etc). It has no no idea if you add properties that can be bound to the class etc.
