Template includes causing problems with perch blocks UI in runway 3.1.2

Not sure if this is related my last post - http://forum.grabaperch.com/forum/09-27-2018-using-page-attributes-as-template-include-in-perch-collection-not-working

Template fields are not displaying in the UI when a new block item is added from a template include inside a collection template.

I have a runway collection template some of which is comprised of a set of blocks in a sub-template (_content_blocks.html) - this is also used in other standard page templates as a template include and causes no problem with the UI in that case.

Each block is itself a template include, i.e. _content_blocks.html:

<perch:block label="Photo" type="image" icon="photo">
     <perch:template path="content/default/blocks/_image.html" rescope="parent"  />
</perch:block>

When I try to add the above block item in Perch admin (Runway 3.1.2), only the block title bar (showing block type rather than label) and the block-add-bar appear in the UI but none of the template fields in _image.html appear.

If I save changes after adding the block, the fields appear fine, and if I copy the contents of the _image.html into the parent template (_content_blocks.html), the fields appear, although the block title bar displays the block type rather than the block label.

This problem doesn't occur when the same _content_blocks.html is used as a template include by another template assigned to a content region - the new blocks display when added and the block title bar displays the block label as you would expect.

Seems like there's a problem instantiating blocks... as template includes.. inside in collections! Anyone else experience similar unpredictable behaviour?

As a quick test, have you tried updating your template syntax? (Just thinking about the elements that might have changes with the update)

<perch:block label="Photo" type="image" icon="photo"> 
    <perch:template path="content/default/blocks/_image.html" rescope="parent"> 
</perch:block>

Sorry, updating the template syntax to the above makes no difference, although there are plenty of other self-closing tags in all the other blocks int the same file.

Just posted diagnostics in other thread: http://forum.grabaperch.com/forum/09-27-2018-using-page-attributes-as-template-include-in-perch-collection-not-working.

Hello Adam,

Seems like there's a problem instantiating blocks... as template includes.. inside in collections! Anyone else experience similar unpredictable behaviour?

I use template includes inside blocks and I don't see the issue you are describing. I'm also on Runway 3.1.2

Thanks Hussein. Are your blocks and template includes in a collection template? This is where I’m seeing the problem. Same blocks and same includes in a standard template assigned to a content region works fine.

I don't use it in a Collection, but I tested it and I still don't see the issue. Can you post your full template?

Thanks again Hussein - I could post the full template but you would't thank me as includes are nested within includes so there'd be a lot to post... & it seems that the depth of nesting is where the problem lies.

The final include which contains the block content was removed from the main template by 3 levels, i.e. walks.html > _listing_common.html > _content_blocks.html > _image.html

Moving the _content_blocks.html up the chain of includes has resolved the issue & block fields are now displaying as expected when I add a new content blocks. It's now structured like this: walks.html > _content_blocks.html > _image.html It seems that 2 levels of includes work fine but 3 levels trips up perch blocks UI?

Now I know the cause of the problem I see others have had problems with nested templates, though there's no mention of any nesting limitation in the docs on template includes: - https://docs.grabaperch.com/perch/content/templates/template-includes/ - https://docs.grabaperch.com/templates/includes/

And there was I happily nesting away, disappearing up my own backside without any problems 'til this strange UI bug appeared!

You can't currently nest includes inside includes.

Thanks Drew - my bad! Same cause for other recent issues experienced here: http://forum.grabaperch.com/forum/09-27-2018-using-page-attributes-as-template-include-in-perch-collection-not-working

I obviously need to flatten out my template architecture - I've been trying to re-use existing templates rather than duplicating template code all over the place!
