Reopening a new output console in the same session

Rafael-Marquez · May 19, 2026, 2:17am

I am testing a new tool that does some simple reporting. it is a modeless tool i am experimenting with. Something I am running into (not sure if this is just normal behavior) is if i click on the report button, the report gets generated. if i close the output window and then click on the report button again, the output window no longer opens. I have to close the tool and rerun the tool for the output to generate. is this common behavior when closing an output console in the same session?

There’s a feature request here:

ScriptConsole cannot be re-created mid-session for persistent panels/modeless windows

New Feature

For dockable panes and modeless windows (`WPFMixin_` subclasses), the output win…dow persists across command executions. When the user closes it, re-creating a functional `ScriptConsole` mid-session crashes Revit regardless of approach. **Attempted fixes (all crash):** - `new ScriptConsole()` + swap into `EXEC_PARAMS.window_handle` + rewire `ScriptIO`/`sys.stdout` — mirrors `sessionmgr._setup_output()` but crashes mid-session - `ScriptConsoleManager.CreateDetached()` with explicit `Show()` on `Dispatcher` — crashes on show - Both with and without pre-registration in `AppendToOutputWindowList` **Suspected causes:** - `SetupDefaultPage()` runs a `DoEvents()` busy-wait in the constructor, causing message loop re-entrancy when called outside the normal startup context - `ScriptConsole` may have implicit dependencies on the startup execution environment that aren't met when constructed on-demand **Expected behaviour:** For persistent panels, closing the output window and re-running any panel method should produce a fresh, functional output window — the same behaviour regular commands get on each run. **Workaround:** None currently.
