Reset(gallery) not working with other functions

Hello all-

 

Many thanks to all active members as I have saved myself from insanity many times in these hallowed virtual halls. Here's my current weirdness.

 

I am working in an edu environment and designing a "quiz" app. Each time I show a new question, I pull the set of answers into a gallery. I want this gallery to reset on each new question so that there is nothing selected. I read several posts and came up with setting the Default property of the Gallery to {} and calling Reset(GalleryName) and that works flawlessly, when it's by itself.

 

I have a button during dev called resetgallery with the above formula in the OnSelect property and it works great. However, I have another button that does a bunch of other stuff to "submit" the quiz answer and show the next question, and with that same formula at the end of those steps, it never works.

This is the Onselect of the Submit Answer button:

************************************************
UpdateContext({QBody:LookUp(KCQOrdered,NewID=ThisKCQC,Question_x0020_Body)});
UpdateContext({QYourAnswer:KCAnswerGallery.Selected});
UpdateContext({QCorrectAnswer:LookUp(Filter('KC Answers',QID.Id=LookUp(KCQOrdered,NewID=ThisKCQC,ID)),Correct=true)});

//(capture current question and answer and correct answer)//
Collect(ThisKCAnswers,Question:QBody,YourAnswer:PlainText(QYourAnswer.Answer),CorrectAnswer:PlainText(QCorrectAnswer.Answer),Correct:If(QYourAnswer.ID=QCorrectAnswer.ID,true,false)});
//Write them to a temp collection//
UpdateContext({ThisKCQC:ThisKCQC+1});
//Count for next quiz question//
Reset(KCAnswerGallery)

***********************************************

But as I said, just Reset(KCAnswerGallery) by itself (in another button) works fine. Otherwise this works as I want. This is more cosmetic and user friendly, but I don't understand why it's not working in just this place.

 

Anyone have any thoughts?

Hey @Sam_Misemer, where is the quiz submission button located? Is it in the gallery itself or outside of it? The only thought I had on this is that it could be a scoping issue. Assuming that the button is in the gallery, that might be causing that portion to not work as it is making changes to the gallery it is in from within the gallery. In other cases, this would probably give a circular reference error but maybe you have found one that doesn't, again assuming the placement of the button. 

One workaround that you might try is to replace the Reset(KCAnswerGallery) with this:

Select(resetgallery)

Basically, this just acts like pressing that button you had for testing. I don't think it will have any issues so you might give it a try.

 

Otherwise, you could try resetting each of the controls within the gallery. This would be similar to what you are currently doing with the gallery but you would replace the gallery name with the control name. You could put all of those Reset functions in a Concurrent function to make it just a bit faster as the resets will happen in tandem and not one after the other. So something like:

Concurrent(
    Reset(Thing1),
    Reset(Thing2),
    Reset(Thing3)
)

 

Those are just some ideas off the top of my head, so feel free to reply with how it goes! I'm happy to follow up and try to come up with more ideas on why it might not be working!

Hi @Sam_Misemer 

You should move every function other than SubmitForm(Form1) out of that button and into the OnSuccess property of the form.  You don't really want these functions to execute unless the form is successfully submitted anyway.  

@wyotim Thanks for the response!

I hadn't thought of the scoping issue but no luck, it was visually next to the gallery, but located on the screen directly, not in the gallery.

 

Your Select(ResetGalleryButton) idea was the fix!! I still do not understand WHY invoking the Reset(Gallery) at the END of the other functions didn't work, especially when you consider that I simply put the Select in the exact same place and it worked fine...

 

Here's the new OnSelect:

***************************

UpdateContext({ThisQBody:LookUp(KCQNewOrder,NewID=ThisKCQC,Question_x0020_Body)});
UpdateContext({ThisQID:LookUp(KCQNewOrder,NewID=ThisKCQC,ID)});
UpdateContext({ThisQYourAnswer:KCAnswerGallery.Selected});
UpdateContext({ThisQCorrectAnswer:LookUp(Filter('KC Answers',QID.Id=LookUp(KCQNewOrder,NewID=ThisKCQC,ID)),Correct=true)});
Collect(ThisKCAnswers,{

Question:ThisQBody,

YourAnswer:PlainText(ThisQYourAnswer.Answer),

CorrectAnswer:PlainText(ThisQCorrectAnswer.Answer),

Correct:If(ThisQYourAnswer.ID=ThisQCorrectAnswer.ID,true,false),

QID:ThisQID});
UpdateContext({ThisKCQC:ThisKCQC+1});
If(ThisKCQC=6,UpdateContext({ExamInProgress:false}),UpdateContext({ExamInProgress:true}));
Select([@ResetGalleryButton])
//Reset(KCAnswerGallery)

****************************

Note the positioning...this way works like a charm, the other way it just ignores the Reset call. Beats the heck out of me.

 

The teachers and students and I thank you very much for the ideas and help!!!

@Drrickryp  Thanks for the response!

 

This use case actually is not using a form, just collections and direct writes using the Patch function to a list. What I am doing is a "quiz" that gets embedded into a sharepoint page at the end of a bunch of content to test the student's retention. It's not a graded thing, just a "did they take the quiz" thing. What I do is post a question (in a text box) based on an ID, then filter the answers list into a gallery based on the question ID. The student chooses (selects) an answer in the gallery, then clicks the Submit Answer button which saves their answer to a temporary collection. At the end of the questions (5), I show them the questions, their answers, and the correct answer, and patch the fact that they took the quiz (at least once) to a list in the sharepoint site. They can take the quiz over and over again (it randomizes the question order each time through), I just patch the list once, so all the work gets done at the client level.

 

I thought about using a form, but the teachers told me they weren't grading the quizzes, just making sure the students went through it, it's more of a study aid.

 

Thanks again for your response, and I agree with your reasoning about the OnSuccess usage 🙂

@Sam_Misemer @I’m happy that worked out for you! I’m stumped as well; it would have been more convenient if it was a scoping issue! If I can carve some time out, I’ll try to make a test app to see if I can recreate that issue. And if I find anything, I’ll come back to report.

 

All the best to you and your teachers and students with this app! And if I can help out in the future, feel free to tag me in your posts! Cheers!
