SmartDashboard - PID Editor Crashes C++ CRio Code

[slibert]

In case this is helpful to others, we've found a workaround:

1) Copy WPILibrary PIDController.cpp/.h into our project.
2) Add new "internal" SetP, SetI, SetD, SetF methods to PIDController.h/.cpp
3) Modify the PIDController::ValueChanged method as follows (commented out code is the WPILib implementation that seems to be causing problems, although we're not sure why):

void PIDController::ValueChanged(ITable* source, const std::string& key, EntryValue value, bool isNew){
/*if (key==kP || key==kI || key==kD || key==kF) {
if (m_P != m_table->GetNumber(kP) || m_I != m_table->GetNumber(kI) || m_D != m_table->GetNumber(kD) || m_F != m_table->GetNumber(kF) ) {
SetPID(m_table->GetNumber(kP, 0.0), m_table->GetNumber(kI, 0.0), m_table->GetNumber(kD, 0.0), m_table->GetNumber(kF, 0.0));
}*/
if (key==kP && m_P != value.f) {
SetP(value.f);
} else if (key==kI && m_I != value.f) {
SetI(value.f);
} else if (key==kD && m_D != value.f) {
SetD(value.f);
} else if (key==kF && m_F != value.f) {
SetF(value.f);
} else if (key==kSetpoint && m_setpoint != value.f) {
SetSetpoint(value.f);
} else if (key==kEnabled && m_enabled != value.b) {
if (value.b) {
Enable();
} else {
Disable();
}
}
}
