Backend Module without CSS/JS in iframe about extension_builder

[liayn]

Maybe compare your BE module with those used in the Core. I guess you overlooked some detail.

But that's what the extension_builder generates for me.
I added a model with some forms and enabled the option "backend module".

Do I have to add something manually to get a correct backend form?
In my tests doing this with extension_builder I always get a incomplete html page within the iframe where the backend modules are shown normally.

Do you see any network error in console? Is your typo3 backend in a subdirectory?
Please try to debug and tell us what you found...

It's no subdirectory and there's no error in console.
It just loads the modul without proper html frame into the second column.
The loaded html starts with
<div class="tx-myext">...</div>

Moving the generated templates from Resources/Private/Backend/... to Resources/Private/... solved the problem.
As I added a frontend plugin and also a backend modul (via builder extension), there have already been templates within Resources/Private/.... But they probably didn't contain the correct wrapper to generate a backend module.

So it seems that the templates for backend modules are not included correctly out of Resources/Private/Backend/... or what do you think?

Thanks for your help.

I could reproduce it. It's obviously a bug.
Thanks for reporting.

Ok I found that this is related to a TYPO3 core bug:
https://forge.typo3.org/issues/82181
If I checkout the last commit before 6e02927806 it works as expected

Great, thanks for helping.
So finally I was searching at the wrong place...
