Toast event in Lightning not working

Question

Hello I am trying to make a Lightning component common to Community and SF1 . This component has been added as quick action on one of the object detail page.

Now when i am using the toast event, it gives me error as

Something has gone wrong. [TypeError: Cannot read property 'setParams' of undefined] . Please try again.

Code for same -

action.setCallback(this, function(response) {
            var state = response.getState();
            console.log('state--->1', state);
            if (state === 'SUCCESS') {
                jobApplicantId = response.getReturnValue();
                fromPos = toPos;
                console.log('fileContents.length -->', fileContents.length);
                toPos = Math.min(fileContents.length, fromPos + CHUNK_SIZE);
                console.log('fromPos -->' , fromPos);
                console.log('toPos -->' , toPos);

                if (fromPos < toPos) {
                    this.uploadChunk(component, file, fileContents, fromPos, toPos, attachId);  
                } else if (fromPos == toPos) {
                    //alert('Job Application Successful');
                    var toastEvent = $A.get("e.force:showToast");
                    console.log('toastEvent -->', toastEvent);
                    toastEvent.setParams({
                        "title": "Success!",
                        "message": "The record has been updated successfully."
                    });
                    toastEvent.fire();
                    component.find("comments").set("v.value", "");
                    component.find("file").getElement().value = "";
                    this.displayJobAppliedButton(component);
                    //component.find("file").getElement().removeAttribute('value');
                }
            } else {
                var errors = response.getError();
                if (errors) {
                    if (errors[0] && errors[0].message) {
                        alert("Error message: " + 
                                 errors[0].message);
                    }
                } else {
                    console.log("Unknown error");
                }
            }

        });

Snapshot - This whole thing is in a helper class? can this be the issue?

Answer 1

From the description and image ,I see that you are using Lightning components inside the Visualforce page. Having lightning components inside the visualforce,you will lose certain events as documented in the guide.The events that are not supported are as below

1.force:createRecord

2.force:editRecord

3.force:navigateToList

4.force:navigateToObjectHome

5.force:navigateToRelatedList

6.force:showToast

Official Documentation On Toast event

I think you should open an Idea on Idea Exchange to support lightning components directly from publisher actions .
