There is no current trace view

Error message

There is no current trace view

What it means

Thrown by FlatDebuggerAPI.requireCurrentView() when there is no current trace program view. The view is an adapter that lets a trace be used as a Program for a chosen snapshot; it requires a current trace.

Solutions

1. Ensure a trace is current before calling view-dependent methods.
2. Guard with getCurrentView() != null.
3. Use getCurrentTrace()/requireCurrentTrace() first, which implies a view can be obtained.

Example fix

// before
TraceProgramView v = requireCurrentView(); // throws if none

// after
if (getCurrentTrace() == null) {
    println("No active trace");
    return;
}
TraceProgramView v = requireCurrentView();

TraceProgramView v = getCurrentView();
if (v == null) {
    println("No current trace view; open a trace first");
    return;
}

static boolean hasCurrentView(FlatDebuggerAPI api) {
    return api.getCurrentView() != null;
}

try {
    TraceProgramView v = requireCurrentView();
} catch (IllegalStateException e) {
    if (e.getMessage().equals("There is no current trace view")) {
        // ensure a trace is open, then retry
    } else throw e;
}

When it happens

Trigger: Calling requireCurrentView() when getCurrentView() returns null, which occurs when no trace is current or the view has not been created.

Common situations: No active trace; the trace manager has not yet built a view for the current snapshot; operations that iterate a trace as a Program called before a trace is open.
