Drag and drop MIDI functionality does not work after reloading plugins

[CatABC]

I useed a floating tile,Set to MidiOverlayPanel,

{
  "ProcessorId": "MIDIPlayer",
  "Index": 0
}

When you load a plug-in in a DAW, it works for the first time, but it disappears when you load the plug-in again.

@BobCat what disappears?

@clevername27 Drag and drop becomes unavailable

I use floating tiles to display MIDIViewer. It works fine for the first time after loading the plugin, but if I remove the plugin and load it again, it will not be displayed. I think there are still some problems with MidiOverlayPanel. I found these historical posts. These problems still occur in HISE4.0.0

@BobCat If I'm understanding you correctly, the issue may be in the temporary MIDI file that's created. Does the problem happen if you drag a different MIDI file — one that you've never dragged before — after reloading the plugin?

[CatABC]

@clevername27 Yes, the problem still exists，After reloading the plugin, floating tiles go directly to blank

[clevername27]

@BobCat Oh, hmmmmmmm…I'm afraid I'm at a loss, then. If you haven't already, can you try creating a new project that only has the problematic feature — and try that? If it doesn't work, the project will be small enough for you to post here on the forum, and I'm sure one of us will try it ourselves. I know how frustrating this can be.,

@clevername27
I think I'm sure this is a bug in HISE, when my entire project only contains one MIDIPlayer, and uses floating tiles for display, it still fails after removing the plugin and then loading it again

@BobCat Works here, try a different DAW

[ulrik]

@BobCat works here as well, tested in Logic, Reaper and Ableton Live on MacOS

[CatABC]

@d-healey I tested with a different host and the same thing happened,

[CatABC]

@ulrik I tested it on Windows 11. Could it be a system problem? This problem is giving me a headache.

[d.healey]

@BobCat Are you building VST3?

[CatABC]

@d-healey Exported VST2 and VST3 have the same problem

[d.healey]

@BobCat are you using the latest develop branch?

[CatABC]

@d-healey Yes, and I use Logic on Mac to perform the same operation, and the situation shown in the above picture also occurs

the snippet you provided works for me in Logic on Mac, is it the same snippet you're showing in the video?

[CatABC]

@ulrik TIt's the same snippet. I tested it countless times.

[d.healey]

@ulrik Please send @BobCat the plugin you compiled to see if it works on their system.

I have provided Windows plugins and MacOS plugins. Please help me test them. I would like to express my endless gratitude in advance.
