Can't open a .rar. Sorry.

View File Unrestricted Invoke Node.xnode One of the difficulties with editing XNodes without the license is that invoke nodes for the XNode class don't show any methods. This XNode acts pretty much like a real Invoke node, but it allows access to all possible methods. You can also right-click and replace it with a real Invoke node.

I have determined that none of the existing abilities is called when the .xnode is placed on the palette. I'm guessing that either it needs another ability that I haven't got, or more likely, a property of an ability, or of the .xnode needs to be different.

Something like this. Grayscale to False Color.vi

I created a handy XNode and placed in on the Functions palette (the same way you place a .VI). The icon on the palette was the XNode's icon, and everything was OK. Later I added the "Help" ability; then the icon on the Functions palette became the icon of the "Help" ability VI. Furthermore, I could no longer place the XNode on a palette. Deleting the "Help" ability returns everything to normal. This happens with both LV 2017 & 2018. I haven't been able to figure out how to correct this. My guess is that there's something about my "Help" ability that's causing errors inside the Functions palette; but what? I thought maybe it was because I had an empty path in the Help cluster, but adding a path to a .html file didn't help. I know it's possible to place an XNode with help on the Functions palette, because you can to that with the Error Ring. I looked inside "Error Ring.xnode" and saw some items in there that weren't in my XNode; I tried adding equivalent items, but that didn't help. Does anyone have any ideas on how to fix this?

Does anybody know how to use the AddLinkerReference method of an XNode? I'm trying to make an app specific XNode that will always live inside a Case Structure, and I want the XNode to be notified when there are changes to the Case Structure (specifically the Selector Label). This method (along with the OnRefeeChange ability) looks like it might be what I need, but I don't know how to use it. Any help would be appreciated.

While using it, I decided I needed one more feature: Placing the XNode on the cursor so I could drop it on a BD. Here'e the latest version. XNode Editor.zip

Here is the updated XNode editor. I hadn't logged into LAVA in such a long time that my old account didn't work anymore; so I created a new one. XNode Editor.zip
