Transition copy fails with clipboard access denied #103

Open EdK-z opened 1 year ago

EdK-z commented 1 year ago

ScxmlEditor v2.5.1.1749, Windows 10 In certain cases, when attempting to copy a transition, get error: ERROR> Aug 15 15:46:49 COPY> Cannot open clipboard: Access is denied

Steps to invoke the problem: 1) Copy non-visual child from any state (eg. onEntry) 2) Paste into other state 3) Attempt to copy transition

The paste is required. If I just copy the child, then copy the transition, it still works.

This only applies to copying transitions. State and all other types of copies continue working normally.

Could not reproduce either with usage of menus or with usage of hotkeys

P.S. Maybe there is an issue of a specific complex scxml

It fails on an entirely fresh instance of editor, new unit (no project) ... Looks like I don't even need to use copy at all, there's some sequence of events... maybe its just timing?... My video capture doesn't capture menus... so you won't see this... I used menus to add the OnEntry and Log. Then I used CTL-Click to create the transition. Then I created the third state Then I select the transition and pressed CTL-C. Then you see the error at the bottom...

Still can not catch. Ok, I will not close it and will check on other devices

It does seem to be related to timing somehow. Sometimes, if I just do CTL-C a few times, it'll finally work. Sometimes I have to use CTL-C on something else, then try the transition again and it works. Here's my PC info...

Your PC is much more powerful than mine, maybe you are right about timings. I will try to test on such configuration
