From 6d78b349452a7d6cdadbd3de437be324a6d042e8 Mon Sep 17 00:00:00 2001 From: iroiro147 Date: Thu, 30 Jul 2026 11:19:03 +0530 Subject: [PATCH] fix(desktop): surface leave-channel rejection in sidebar dialog Leaving a channel you solely owner was silently rejected: the sidebar dialog closed immediately regardless of success or failure, and the relay's error message ("you are the only owner") never reached the user. This change adds error and pending state to LeaveChannelAlertDialog: - The dialog stays open when the mutation fails, showing the relay's error message as a destructive-foreground paragraph - The dialog only closes on successful mutation - Cancel and Leave buttons are disabled while the request is in flight - A new leave request clears any prior error This matches the behavior already present in ChannelManagementSheet's leave button, which does surface errors. The two entry points now agree.
