Type Conversion Error Due to java.awt.Paint on Dataset Tags

There was a previous discussion on this at Can't use Color Datatype in Dataset tag anymore, error: 'Invalid DataType for Dataset.'

Version: 8.1.44
Module: Vision

According to that post it was supposed to be fixed all the way back in 8.1.15 but I am still experiencing this issue in 8.1.44 but so far only on shapes. Specifically a Union shape overlay I am using for a motor to indicator status. If I copy the dataset from say a multistate indicator this is what I get:

"#NAMES"
"state","animationIndex","animationDuration","background","border","foreground","text"
"#TYPES"
"I","I","I","clr","str","clr","str"
"#ROWS","8"
"0","0","50","color(213,213,213,255)","border(line;color(0,0,0,255);1)","color(46,46,46,255)","STOPPED"
"1","0","50","color(71,255,71,255)","border(line;color(0,0,0,255);1)","color(0,0,0,255)","RUNNING"
"2","0","1000","color(255,140,0,255)","border(line;color(0,0,0,255);1)","color(0,0,0,255)","BYPASS"
"2","1","1000","color(255,140,0,255)","border(line;color(0,0,0,255);1)","color(46,46,46,255)","MANUAL"
"3","0","500","color(222,27,27,255)","border(line;color(0,0,0,255);2)","color(0,0,0,255)","FAULT"
"3","1","1000","color(213,213,213,255)","border(line;color(0,0,0,255);2)","color(0,0,0,255)","FAULT"
"4","0","1000","color(255,255,0,255)","border(line;color(0,0,0,255);1)","color(46,46,46,255)","STANDBY"
"5","0","1000","color(71,255,255,255)","border(line;color(0,0,0,255);1)","color(46,46,46,255)","INTERLOCK"

So the color is setup as a string which works and I pasted this to a dataset tag that I use for a style binding. When I take my shape and manually setup a customized style when I copy it I get this:

"#NAMES"
"state","animationIndex","animationDuration","fillPaint"
"#TYPES"
"I","I","I","java.awt.Paint"
"#ROWS","8"
"0","0","50","color(170,170,170,51)"
"1","0","50","color(71,255,71,128)"
"2","0","1000","color(255,140,0,128)"
"2","0","1000","color(170,170,170,51)"
"3","0","500","color(255,0,0,128)"
"3","1","1000","color(213,213,213,89)"
"4","0","1000","color(255,255,0,128)"
"5","0","1000","color(71,255,255,128)"

Which gives you a type conversion error due to java.awt.Paint under #TYPES. But if you change it to clr or java.awt.Color it fixes the issue as noted here: Can't use Color Datatype in Dataset tag anymore, error: 'Invalid DataType for Dataset.' - #11 by pturmel from the forum post I linked above.

Are there any plans to change this so that users don't have to do it manually? Or is there something I am doing wrong that still causes this on certain components which in my experience has only been shapes so far.

Hmm. This is tricky. Paint is an interface that encompasses gradients and other types of "fill region with colors" Java classes that are, fundamentally, possibly not serializable [1]. So it's not incorrect to annotate the dataset in the shape group as accepting a Paint, and it's also not incorrect to require that the value in the dataset be a concrete type like Color rather than the interface...

You're not doing anything wrong, but it's likely you'll have to continue manually working around this behavior (essentially, opting in to a more restrictive set of possible fills for shapes) for the foreseeable future.

  1. outside of Java's built in magic serialization that's a persistent security issue ↩ī¸Ž

That makes sense. It is not to much of a hassle to make the change manually. Once I create the original I apply it to a dataset tag anyways to use in future styles so it is a one and done thing. I was more so just curious if there was a way I was going about it that wrong. Glad to know that is not the case.
