Kentico 12: The page with workflow unable to populate the widget.

P/s: When I disable the Check-in/Check-out in Workflow setting. Use check-in/check-out = No, everything is working correctly as normal. So is it a bug of Kentico 12?

Thanks

Are you using the right API to update the latest edited version of the page? Please see the API example. You may need to call also the CheckOut and CheckIn to ensure proper versioning - in API it is not about content locking so even if it is disabled in the admin UI, you may need to use it in the API. See the code comments.

Hi @Juraj,

Thanks for your reply.

With my current issues, I think the content locking has a problem because I want to use CheckOut and CheckIn on my page but the page did not save my widget properties settings.

But while disabled CheckOut and CheckIn in the admin UI, the page did save my widget properties settings and apply workflow as normal.

Do you think the DocumentEvents.Update has a deathlock when I try to call (TreeNode)page.Update() in my event Document_Update_After?

Thanks,

Well, it depends on the code - the Update() method may invoke the handler again. I would maybe update the data in the before update event and in this case it might not be necessary to call page.Update(). And it also depends whether you want to keep track of these changes in the version history. If not, you do not need to use the CheckIn/Out in the code.

Hi @Juraj,

As your suggest idea, I have solved my issue by prevent the page.Update() by unnecessary. But now I have a new issues after that.

In the event DocumentEvents.Insert.After, I tried to initialized all necessary widgets for page by loading JSON string object to DocumentPageBuilderWidgets of DocumentCultureDataInfo as this article. Example:

    protected override void OnInit()
    {
        base.OnInit();

        DocumentEvents.Insert.After += PreLoadWidget;
    }
    private void PreLoadWidget(object sender, DocumentEventArgs e)
    {
        var docCultureInfo = DocumentCultureDataInfoProvider.GetDocumentCultureInfo(e.Node.DocumentID);
        var widgetsJson = docCultureInfo.DocumentPageBuilderWidgets;
        //Create widget json
        if (widgetsJson == null || widgetsJson == String.Empty)
        {
                docCultureInfo.DocumentPageBuilderWidgets = "{\"editableAreas\":" +

But the widgets are not load correctly when creating new Blog with content locking.

There is some points from my investigate:

1. This issue only occurs when using content locking Check-in/ Check-out
2. With enable Check-in/ Check-out, the page cannot initialize all widgets when creating new Blog. → not OK
3. With disable Check-in/ Check-out, all widgets are initialized when creating new Blog. → OK

Is my implementation missing anything? Could you please provide any correction?

Thanks

When using content locking it means there is a workflow. Are you editing the right version of the page? From the code it seems that you are editing just the latest published version of the page. While, in the admin UI the Pages app is displaying latest edited version and these an be different.

Hi @Juraj,

Thanks for your idea!

I have checked again and found that the page have 2 version 1.0 and 1.1 when creating new page. It also auto set in stage Checkout while I did nothing.

But when I tried to call page.UndoCheckout() in the end of method PreLoadWidget(), it still not working and throw exception message: "It no previous version to roll back".

What should I do in this case?

Thanks

would it be possible to provide some detailed and step by step description how to reproduce the issue? So I can debug it on my side. I think we are missing here something simple or maybe you are just using wrong events to do what you want to do.

Hi @Juraj,

Please following below steps.

1. Add custom event to initialized some widgets in DocumentEvents.Insert.After
2. Go to CMS, create a basic workflow with new step Approve and enable content locking Check-in/Check-out
3. Create a Blogs folder and Blog page type
4. Apply workflow for Blogs folder and check config "To this page and its children"
5. Create new Blog, input contents then Save

→ Expected: New Blog page is created with initialized widgets.

Actual: New Blog page is created with blank, no widgets are initialized.

Hi @Juraj,

Thanks for your efforts and supports!

I think I almost reach the goal, I will try with your suggestion.

And one more thing, it seem like you had not enable Check-in/Check out on your video yet. Could you please confirm that even if enable content locking, it still work OK?

Thanks.

Good catch! I totally forgot about it. However, in the admin UI, where it is used for content locking for exclusive access, it makes no difference. New video with check in/out enabled for the workflow here.

Hi @Juraj,

With your help, the issue is completely solvable. Again, thanks for your efforts and supports!

Best regards,
