JS error in signature pad

Hi @dalpasso, The updated version does not contains .install file so no hook update happened. Therefore this version is same as the latest version.

I am not able to get this error and version update does not contain any additional code. So, I am unable to identify the problem.

Please explain it briefly that what are you doing.

Hi and thanks for your reply @shubham_jain I will try to explain the situation a little more:

D9.5.10, Signature Field 8.x-1.0-rc1

We have an existing form with a working signature field. If I complete an upgrade via the GUI (no composer etc.) to version 2.1 and try to load the same form the signature panel is not visible. No errors in logs and can submit the form with no errors but unable to take a signature as only the data field is visible.

If I look in the console I see the js error with signature_pad, line 88, Uncaught TypeError: t is undefined.

I also noticed that if I try to edit the form display to hide the signature data filed it is not hidden and the form is unchanged.

Hi @shubham_jain,

I have done a test on a fresh install of D9.5.10 and have seen that the color (deprecated) module is enabled when installing v8.x-2.1. This would not happen when doing an upgrade in my environment so I think this explains the undefined t console error. I'll remove it from the issue.

v3.0.3 doesn't seem to need color, but it's pad is not visible on the edit content screen. The data portion is enabled by default and if I disable the data portion all I get is the field title on the edit screen. The "undefined (reading 'getContext') error is visible in the console window.

Hi @shubham_jain,

I'm not sure if this is a correct solution but I noticed that the template was not being loaded. I've added the theme in to the SignatureWidget class which has loaded the signature pad correctly.

$element += [
'#theme' => 'signature',
'#type' => 'textarea',
'#default_value' => $value,
'#attributes' => $sign_data_attributes,
'#attached' => [
'library' => ['signature_field/signature_pad'],
],
];

I can't submit the form in my environment right now but do you think this is a safe solution to implement?

Thanks,

Hi @dalpasso, sorry for the late reply.

This approach is right because it will only attach library if the field type is textfield.

Hi @geoanders and @saranya ashokkumar, please review it.
