🎨 UI/UX: Missing null check before accessing MainWindow.unityInstallationsSource

[halinhtvn3a]

🎨 UI/UX Improvement

Problem

The code accesses MainWindow.unityInstallationsSource without checking if it's null. This can cause a NullReferenceException when the window is opened before the main window has initialized the data source, leading to a crash.

Severity: medium
File: UnityLauncherPro/UpgradeWindow.xaml.cs

Solution

// Add null check before using ItemsSource
if (gridAvailableVersions.ItemsSource == null)
{
if (MainWindow.unityInstallationsSource != null)
{
gridAvailableVersions.ItemsSource = MainWindow.unityInstallationsSource;
}
else
{
// Initialize with empty collection or show message
gridAvailableVersions.ItemsSource = new List();
}
}

Changes

• UnityLauncherPro/UpgradeWindow.xaml.cs (modified)

Testing

• Existing tests pass
• Manual review completed
• No new warnings/errors introduced

same for this: slightly different check and made one additional null check later in the code, so i'll close this.
