@edvin @ron Hi again, I almost finished doing, what i wanted, but there is another strange behavior - I want my model to have default value of Occupation. I just added this line model.item = Occupation(InstrumentSet(Instrument("Nail"), Instrument("Hammer")), Activity("Have fun”)), but it causes an exception right after start java.lang.Exception: Value has not been assigned yet! at tornadofx.SynchronizedSingleAssign.getValue(Properties.kt:158) at func.test.OccupationEditor.getInstrument2Model(Instruments.kt) at func.test.OccupationEditor.access$getInstrument2Model$p(Instruments.kt:38) at func.test.OccupationEditor$root$1$1$1$1$1$4.invoke(Instruments.kt:65) at func.test.OccupationEditor$root$1$1$1$1$1$4.invoke(Instruments.kt:38)

Looks like you're accessing occupation before it is assigned.

Why is occupation a field member, I don't see any other references to it.

Btw, you can do

add(occupation)

instead of

this += occupation

.

There is something about this code that makes it look very complex. Not sure what it is, but I think it could be written with less complexity.

Hey @ron @edvin is it right that, at the moment tornadoFx has a preference mechanisms, which is using the

java.util.prefs

. I some how I don't like the

java.util.prefs

because it has not a simple way of storing

Map's

and

Lists

(Json). We could either implement something on top of

java.util.prefs

to support that or run our own (Then we need to think of how we store the information in a OS specific way). Did you guys ever had the need for a better way to store settings?

@nimakro Maybe

config

suites your need better?

Hmm.. No, maybe it doesn't. It would require you to save your data as JSON.

@nimakro Let me think about that for a second.

If your data can be encoded as Strings, we might be able to support other datatypes, or at least add spesific support for JSON.

@edvin I will check out

config

and think how settings could be managed in a nice way with tornadofx

@nimakro Just committed: "`config` can now read and write JsonObject and JsonArray"

You can do

config.set("myKey", someJsonObject)

and retrieve it with

config.jsonObject("myKey")

Same for

jsonArray

you can store maps and lists in Preferences if you make them json or xml

I'll add the same specific JSON support to Preferences then 🙂

grins I think I am the only one using the preferences 🙂

Hehe, probably 🙂

@edvin well, there is repeating logic in the view declaration - It can be moved out to the extension method for example

@edvin Your the man .. @ron Ah oky I didn't know that

I know I stored a lot of lists in Preferences using xstream

@ron The java api from preferences feels so old.. :-)

its been there since 1.4

Yeah, the Preferences API is a bit clunky. It has functions like

putBoolean

etc, which are kind of meaningless, but we can't override.

remember that in 1.4 they still has to support windows 3.1 and sunos

life was not easy then 😉 (feeling old)

I wrote an mp3 player in java 1.2

Yeah that's crazy🎉 🙈

Who needs windows 3.1
