Secondary Window doesn't work for GLSP VS Code extensions in Theia #1193

Open planger opened 11 months ago

planger commented 11 months ago

It has been reported in https://github.com/eclipse-theia/theia/issues/13165 that GLSP editors packed in a VS Code extension can not be extracted into a secondary window in Theia, even though it should work as GLSP editors in VS Code extensions are based on Webview.

For me that neither works in Theia nor in VS Code. In VS Code they explicitly set a flag that causes an error message when trying to open a Webview Editor in another window:

The relevant code is here https://github.com/microsoft/vscode/blob/75b1639461b53dc51380a61532aabdd502c4c718/src/vs/workbench/browser/parts/editor/editorPanes.ts#L133-L142 and https://github.com/microsoft/vscode/blob/75b1639461b53dc51380a61532aabdd502c4c718/src/vs/workbench/contrib/webviewPanel/browser/webviewEditorInput.ts#L32-L34.

I tried it with another webview editor in Theia and there I managed to get it to work but the GLSP editor does not. So I think we can look into getting that to work for Theia somehow but that would still not make it work in VS Code.

I don't think the linked code should be a problem in Theia because we're not going through "openEditor" when moving a webview to the secondary window. Something else must be going on here.
