@jchildress By default, nested selectors are just that: nested. So

defaultColor0 {
    chartLineSymbol {
        ...
    }
}

results in

.default-color0 .chart-line-symbol { ... }

(note the space). To make a union of selectors, you need to use

and

.

@edvin @tieskedh at first I thought "what in the world did I do?" but now I vaguely recall there was a reason for this madness.

It probably can be shortened to

backingList.asSequence().filter(predicate).toList().forEach

thank you... trying now...

@nimakro commented on @edvin’s file : But I might build one too, when everything is working 😀 🙈

But when I collect things into a

toList()

before turning it into a

Sequence

again, it's because I'm dividing the process into stages for a very stateful reason.

I'm guessing these are collection extension functions, like the

moveUp{ }

and

moveToTopWhere{ }

. You need to observe all the elements first before taking action on them, otherwise your observation and action operations will start to undermine and compete each other.

@Ruckus that worked perfect, thank you very much.

@thomasnield If I'm right, you mean that it's meant as a pause function, between evaluating and changing the tableview?

@thomasnield Aha, I didn't know that. I think your Rx foo makes you think about stuff I've never even considered 🙂

@nimakro I might look into making it a split keyboard later on actually!

@edvin Awesome then I am all in hehe..

my mistake on the "franework"

@tieskedh Yes. It separates the stages between evaluating and changing the tableview. @edvin actually haha, yeah that is a pattern I learned in Rx. But I think that principle applies anywhere in fluent functional programming where you have to consider the source is going to be fed into a sequence that modifies the source.

Here's a simpler example:

@User uploaded a file: Untitled

I'm attempting to append the reversed strings to the source while I'm sequencing it. I'll get a

ConcurrentModificationException

because I'm reading and modifying it at the same time.

But adding a

toList()

in the middle resolves everything

@User uploaded a file: Untitled

Technically, I don't have to turn the middle

toList()

back into a Sequence, but you get the idea.

Actually come to think of it, I think the

ConcurrentModificationException

would occur for the

TableView

operation too.

@pim I see why I couldn't find anything wrong with DataGrid - it works fine when you operate on the items property of the grid itself, but not with a bound list as you said 🙂

The

itemPropertyChangeListener

isn't firing.

@pim Fixed 🙂 I still think there might be something we need to handle with regards to selection when objects are removed.

@mp I did, let me check what library I'm using.

@User uploaded a file: Untitled

I'm using Tyrus. Had no issues, using it in a TornadoFX app.

@edvin Cool! Checking now 🙂
