Saving images when using inline blocks causes JS errors.

[swytch]

Adding a new image / updating an image, fires a POST to a missing url and then errors in javascript. Same repo to replicate here : https://github.com/swytch/bugs.

This doesn't inhibit saving the block.

However using the nested block in the same repo, and adding an image inside will stop the image from saving. Uncaught SyntaxError: Unexpected token '<', " - which looks like it's returning the HTML for the editform instead of JSON. I think these are related, so I'm sticking both issues in here.

I can't reproduce this. Please add a series of explicit step-by-step instructions for reproducing this.

I can't reproduce this either. Please add a second set of step-by-step instructions for reproducing this one.

We are experiencing probably the same issue. Maybe we can shed some light on how to reproduce this.

First some context / findings:

• we are using Elemental 5.2.3 and SS 5.2.12
• we are using Elemental in BlogPosts, so the ElementalArea is loaded not in Pages but Blog (admin/news/)
• if we edit the same page in the pages section, the are no js-errors and the page can be saved without problems
  • so instead of /admin/news/SilverStripe-Blog-Model-BlogPost/EditForm/field/SilverStripe-Blog-Model-BlogPost/item/659/edit/
  • use the same ID in a different pages-section: /admin/pages/edit/show/659/
• using inlineEditable solves the problem also

Reproduction steps

• set the DNADesign\Elemental\Extensions\ElementalPageExtension on the BlogPost pagetype
• create an Element with a text and image
• in the CMS, create a new blogpost and add the text-image element
• add an image and some text, save the page
• observe the console error Uncaught SyntaxError: Unexpected token '<', "
  • the expected JSON is indeed no json, but the HTML of the form.
  • this is caused by the URL returning HTML instead of JSON /admin/news/SilverStripe-Blog-Model-BlogPost/EditForm/field/SilverStripe-Blog-Model-BlogPost/item/659/ItemEditForm/

Maybe the screencast makes it a little better to understand. The first part is editing in the Blog-section, the second part in the Pages-section (yet it is the same blogpost / page):

@baukezwaan can you please check if this is fixed in 5.3.1+?
I think #1267 will have resolved it.
