Bug: Signature Initial Value

[Fabian_Weller]

As mentioned here it is possible to use a background image for signature capture by using an initial value.
This was working once, but it’s not working anymore.
When you draw the signature it will delete the background image.

Do you have reset on edit on the signature field?

[Fabian_Weller]

No.

@Steve Should I contact the AppSheet Support?

Fabian:

Should I contact the AppSheet Support?

Nope. There was some brief internal chatter about your post, so I thought you’d gotten a response. Sorry.

The developer guidance:

This clearing on unlock I think is particular to signature type. He could probably just use Drawing type instead.

[Fabian_Weller]

OK thank you.
But before in 2017 the signature would work with initial value.
So you where able to use an initial value and the signature would just be annotated on the initial image.
I’m okay when the signature would get deleted by unlocking.
But it should not delete the initial value.

This is a screenshot from one of my PDF Report from 2017. You see the initial value was just a line to draw the signature on it.

I'm having the same problem. Did you find any solution?

I've been trying to use a background image, and observe inconsistent behavior. So, it would be helpful to know whether the feature simply doesn't work or I should continue troubleshooting to figure out what I'm doing wrong.

@lizlynch, if this thread still represents the current state and it's not possible to use a background image in a signature type column, the Capture signatures and drawings - AppSheet Help should be updated--either to note the current bug or, if the original functionality isn't going to be reinstated, to remove the explanation that it's supposed to be possible to use a background image.
