Warning : Undefined array key "to_sid" in WorkflowTransitionElement::copyFormValuesToTransition() line 356 when using Ajax button from other field

+1 Facing similar error, I have an eck entity referenced in the user entity, where the eck entity is created on the user register form using IEF. This entity has workflow already attached to it, After using the latest version 1.8, I am getting this error when saving the user register form This value should not be null

I have IEF fields too in my form like you Jaswinsingh !

Hi @dcoppel @Jaswinsingh, I have a fresh Drupal site. Could you tell me the steps to reproduce this issue so I can work on the fix? Thanks!

Hi @IGhosh,
Thanks to help us !

You can try to create a node type with a file field and a field type of workflow state.
Then you can create an other node type with only two text fields.
Then after installed IEF module, you can add in the first node type a field that refer to the the second node type (to add the fsecond form in the first one).
Then try to add a node base on first node type to see if it works.
Thanks for your help.
Regards

I now see 2 use cases:

First:
- have a node type with Workflow and File
- create a node, add a file, save the node. Erro occurs because the 'triggering element' is not the save button, but "field_file_0_upload_button". After saving again, node seems to be saved correctly.
- the error does not occur is no file is uploaded.

Second:
- have a node type with Workflow and IEF.
- Did not test, but may have the same test script and result.

Please check attached patch.

Hi @johnv,
Thanks for your post.
I was intalled your patch but I have the same result.

1- Loading file : An error displayed after file load (Error: content has no workflow attached. The data is not saved.), this error is just up to file field but the file is loading fine.

2- I can submit the form for a new node but I can't submit the form when modifying the node : general form error message appears : This value can't be null.
Thanks for your help.

Thanks,
do you use select/radios in workflow difeinition, or action button/dropbutton?

And your file field is attached to the entity/node itself, not to the workflow?

Hi,
I use actions button in my workflow. And my field file is attached directly to my entity/node.
Let me know if you need more informations.
Thanks for your help.
Regards

Working on this. I think i found a Solution.
Problem was a test on isNew() Which is True after adding/removing the file.

Cleaning up the code now.

Hi @johnv,
I just install and test your last commit and the two problems I had seems to be correct now !
Thanks a lot !

I'm encountering an issue applying the patch. It's returning this error on my end:

patch: **** Only garbage was found in the patch input.

   Could not apply patch! Skipping. The error was: Cannot apply patch https://www.drupal.org/files/issues/2024-06-07/workflow_3452716_8_undefined_key.patch

I applied this using composer-patches.

There is no patch provider for this against 1.8 version. Please use dev version.

Hi @johnv,

Any chance of creating a new release with these fixes in the next few days?

Yex, I will this week.
I am waiting for response on 🐛 TypeError: WorkflowTransitionElement::copyFormValuesToTransition() (line 356) Needs review

I'm unsure if this will help, but let me share my experience.
for context, I have a node type using a workflow and I'm using the 'Workflow transition form' widget and a field with Entity Browser.

While creating a new node, and running Ajax (opening entity Browser) I get:
Error: content has no workflow attached. The data is not saved.

I tried to install the dev version but started getting this error even without touching the form:

TypeError: Drupal\Core\Field\WidgetBase::errorElement(): Argument #1 ($element) must be of type array, null given, called in /var/www/html/web/core/lib/Drupal/Core/Field/WidgetBase.php on line 580 in Drupal\Core\Field\WidgetBase->errorElement() (line 646 of /var/www/html/web/core/lib/Drupal/Core/Field/WidgetBase.php)

For now, I locked it to 1.7 in composer.json
"drupal/workflow": "1.7",
and it works well.

In 1.7 and prior $form["field_wf_status"]["widget"][0]["workflow_transition"]["#value"]) was set and in 1.8 is NULL

@rfmarcelino, Thanks for your response.
Regarding the error 'Argument #1 ($element)', did you change anything in the settings for 'Manage form display' of the workflow?
