Bug ID: 444231 Summary: Illegal null property access resulting in `TypeError`s Product: plasma-systemmonitor Version: master Platform: Other OS: Linux Status: REPORTED Severity: minor Priority: NOR Component: general Assignee: ksysguard-b...@kde.org Reporter: m...@ratijas.tk CC: ahiems...@heimr.nl, plasma-b...@kde.org Target Milestone: --- SUMMARY When switching pages, loading some of them generates QML/JS `TypeError`s. It only happens on some pages, and only during first time loading -- I guess after that they get cached or something. I took a quick look at the code, but couldn't figure it out immediately, hence filing a bug for later(tm). Also, it doesn't seem to break stuff. I think properties eventually receive intended values during same update cycle of event loop, before they get a chance to display inconsistency on a screen. STEPS TO REPRODUCE 1. Launch plasma-systemmonitor. 2. Select pages from the sidebar, one by one. OBSERVED RESULT file::/main.qml:25: TypeError: Cannot read property 'title' of null file::/main.qml:81: TypeError: Value is null and could not be converted to an object qrc:/GlobalMenu.qml:32: TypeError: Value is null and could not be converted to an object EXPECTED RESULT No errors SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.23.80 KDE Frameworks Version: 5.88.0 Qt Version: 5.15.2 Kernel Version: 5.14.12-arch1-1 (64-bit) Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-6700HQ CPU @ 2.60GHz Memory: 15.6 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 970M/PCIe/SSE2 ADDITIONAL INFORMATION -- You are receiving this mail because: You are watching all bug changes.
