Canvas App value in not compatible with datasource


Im have an issue with my varible that I have to use in Item property bud system says its not compatible with datasource. 
I have Gallery and 2 forms. I take data from gallery thru select edit them in first Form than take submitted data from first and want to use then in second with variable declared on succes in previous form it works except for the last step, last form where I try to put my variable into Item property and its not compatabile with datsource. Data source is same every where on gallery and both forms. Any idea would be  appreciated.




Ah wait I don't get the error if I change mine to :




I still try to check how you can keep the form in Edit with the new record





I still try and check on it, how you can keep in Edit form the value without getting an error.

Why not try this simpler approach?


1. OnSelect of a first button:





1b. Make sure Variable set for Item for Form2






2.  Now the fields from the item being cloned are copied to EditForm immediately when pressing the first button.

Now just edit the form to your liking.

Finally, click the Second button to submit the form with new data.


Second Button Onselect:



"Form2" would be name of your Form.




3. Done - see it create new item in data source directly when clicking second button. It have same content as the copied item, with whatever changes I put in there from the form. In this case I added numbers to the title before pressing second button.



Could this way above work for you instead?


Or is your requirement must create the item cloned with new ID right away in SharePoint then bring this cloned item in and then edit it afterwards and cannot do like above?




Wait this way might have problem, it edit the existing item not make a new one. Let me check for another way.

Well the full proces from user prespective has to be. 
1. User picks record from gallery
2. Form1 opens up with filled data from gallery -> user has to change some data and submit them 
3. Form2 opens up with filled submitted data and user has to change again couple thing and click save that will create new copy its like proces of replacing old thing for new and at the same time keeping the old record.  

The proces I described as it is now works same as yours it just wont create the new record 😞 



Ya I am checking it I might try to see if I can have all the 3 steps for you with example.

That would be amazing thanks 😊 Im lost and sad from it on papper it looks so easy to do and it keeps me from progressing thru the app 😞



I have working method for you soon I tell you it.

You can get this result:



Here in above, 


1. A precursor to a clone is created (without editing anything) - the clone is not created yet here.

2. On the second screen, changes can already be made. After using button, the clone is made with any changes from here.

3. On the third screen, the same clone from #2 is edited with further changes.

4. If you want to edit again and again in more chains than this, repeat a similar approach like in #3.


You can try it like this:


1. Screen1


Form1_2 DefaultMode as FormMode.View

Form1_2 DataSource as List01 (your real data source)

Form1_2 Item as Gallery1.Selected


Also presuming a Gallery on this page, Gallery1:

Gallery1 should have Items as List01 (your real data source)

Gallery1 DisplayMode as Edit




OnVisible Screen1 as this:







OnSuccess of Form1_2 as this:



Set(glbNewCopy, Patch(Self.LastSubmit, {ID: Blank()}));





Screen1 Button as this:







Replace Form1_2 in above with Form that is on this first screen. Screen2 replace with name of next screen.


Reason of the above is to make it very clear - here, no changes should be made yet to the stuff for this first form part - because if any are made in this first form part before SubmitForm called here for first time, this will already change the existing record which is probably not desired. So to make it very explicit, the mode is set to View. Then on button press the code quickly set it to Edit (it is needed to do this or it won't work correctly) then to use the trick mentioned by @RandyHayes  for OnSuccess to begin to clone the record (yes that same trick he gave actually does work, by the way, but must be used in specific way - this also require to set the form Edit mode, that's why it is set to Edit mode quickly and back to View again after done) in order to make a clone of it. When done this way I do not get that error of the mismatch type.


But keep in mind the purpose of this was just to make a clone of the Record that a Power Apps Canvas App Form Control would understand - so that it would not keep editing the actual existing ID record - but to eventually create a new Record instead on the Data Source side and auto-assign it with new ID - yet somehow for this to happen even while form is in Edit mode (since New mode cannot take pre-populated values).  This part with the trick strips the ID out to prepare it to be creating new ID when submitted even in the Edit mode - however note that the new record has not been made just yet on the Data Source side, this is what the next step will be. We need the next step, which involves another Form in Edit mode (for clarity purposes and for this example) whose Item property is pointing to the Variable we just Set in the first step - this is so we could get a prepopulated form in Edit Mode, but now when we submit this second form, we will get the actual clone created. Also here in this step, we can already make changes even before the clone is created for very first time in Data Source side.


Now the next part, in Screen2 do like this:


Form1_1 DefaultMode as FormMode.Edit

Form1_1 DataSource as List01 (your real data source)

Form1_1 Item as glbNewCopy


Button Onselect (the button on Screen2) as 








Finally the record created clone in data source for first time, and it have some changes too that were desired from original record if they were put there in that second form - otherwise it will keep same values.


OK now to make even more changes to same record, let's suppose - do like this:


Screen2_1 (third screen)


Same for everything as the second screen above with copy of same form and same button, except for this Form put for Item property as follows:








And for this Button should be:









And now add another screen 4th screen (Screen3)


In this screen just a Label and it says It's Finished.


That's it. It works and you can check it on the top of this posting the visuals, where it is shown working and how it is creating the record in the data source the first time, with changes, then taking another set of changes on same record again.


Obviously this all can be placed in one screen if you really wanted to and knew what to show and hide but it is separate just for the clarity in this case as example. If it is clearer for you like that too you can keep in separate screens as well.


Anyway check if the above help you now @OndrejBriza
