Signature functionality for my App

(0) ShareShare

Hello Community.

In my Asset app, I have two fields for SignIn and Signout which work fine using pen input.

1) For permanent assets, the user signs for the item (Signout) and this works fine.

2)For temporary assets, the user has to sign for the item (Signout) and this fine as well. However when they return the asset, they are supposed to again sign against the item (SignIn). But when they sign in, the original sign out signature is removed. 

The code to save both sign in and sign out signatures is embedded on the same Save button. 

 

SignOut functionSet(varBlobOut,JSON(signout_Signiture.Image,JSONFormat.IncludeBinaryData))

SignIn function:     Set(varBlobIn,JSON(signin_Signiture.Image,JSONFormat.IncludeBinaryData))

 

This the code on the save icon: OnSelect;

If(IsBlank('AssetTracker'.signed_out),Set(varBlobOut,JSON(signout_Signiture.Image,JSONFormat.IncludeBinaryData)),Set(varBlobIn,JSON(signin_Signiture.Image,JSONFormat.IncludeBinaryData)));SubmitForm(Form2_1)
 

what I want to happen when I Save. 

if the signed-out column in SharePoint has data, the Signout function is ignored and only the SignIn function is executed.

I will appreciate assistance to have this working!

    What do you have as the defaults for both of the signature datacards in your form as well as the update properties? My guess is when signing in the asset, the sign out field is being updated with a blank variable or something.

    The default value for each data card is pointing to their default SharePoint list column.
    ThisItem
    .signed_in and ThisItem.signed_out.

     

    On the second point, that is exactly what happens. What i want is; if there is data in SharePoint's sign out column, only update the blank records rather than the entire record.
