Sorry for reviving an old thread but would love to do this exact same thing with my Blu-Ray player and going through the developer guide did not help.

Right now I have:

Activity "RF Devices" that contains Page "Blu-ray" that contains the two tagged widget/button Play and Pause.

I added what is required as per LP post #2 but taking into account the above and Firmkey 1 for the activity script:

function doPageStart() {
if(System.getGlobal("Blu-ray Play/Pause")=="Play") {
GUI.widget("PS_FIRM1").label="Play \uF087";
}
else {
System.setGlobal("Blu-ray Play/Pause","Pause");
GUI.widget("PS_FIRM1").label="Pause \uF085";
}
}
//
function bdPlayPause() {
if(System.getGlobal("Blu-ray Play/Pause")=="Play") {
CF.widget("Play","Blu-ray","RF Devices").executeActions();
System.setGlobal("Blu-ray Play/Pause","Pause");
GUI.widget("PS_FIRM1").label="Pause \uF085";
}
else {
CF.widget("Pause","Blu-ray","RF Devices").executeActions();
System.setGlobal("Blu-ray Play/Pause","Play");
GUI.widget("PS_FIRM1").label="Play \uF087";
}
}


Now I'm getting the following error from the console:

ProntoScript error: ActionList Error
Offending activity script: Tag: 'Blu-ray'
Offending line #17: "CF.widget("Pause","Blu-ray","RF Devices").executeActions();"


Any ideas how I can solve this?

Thanks,

Martin
