TYPO3 Core

Here comes the generated code again:

Generated code outside table (as it is correct)
< p > &nbsp < / p >

Generated code inside table:
< p > < / p >

Related to #6642 , which kind of confirms this error.

Bug 0006642 is listed as "resolved", but the problem exists here with TYPO3 version 4.2 and rtehtmlarea 1.7.4. so it seems that the issue is still unresolved.

You're right, #6642 is marked as solved; it seems that Stanislas has adopted the provided solution.

As mentioned there, the solution can't solve the issue for p-tags within table cells - so that's why I was pointing to it. Unfortunately without being able to give a better suggestion.

Funny bug, but the missing nbsp; is realy leading to a htmlarea block.

I remember having spent quite some time digging into this, but wasn't able to find the reason for p-tags without innerhtml not being editable (maybe even this idea is misleading).
If you're reading Stanislas and have more insight for this behaviour, I'd be grateful to read about.

Isn't it possible to just add the  ?That would solve the problem.

What I'd think is that adding [AND]nbsp; is not more than a clever workaround. Applying it to table cells would mean the need to implement some post processing table parser; which would mean at least some extra effort as well.

Solving the original problem (why does htmlarea not show p-tags when no child node within?) seems to be the way to go for me rather than curing it's symptoms... but that's just my opinion.

This is a difficult issue because the browsers simply do not render empty paragraphs.

But, is it really a good practice to insert paragraphs inside table cells? Why not use RTE.default.buttons.table.disableEnterParagraphs?

I am with you on that point Stanislas - but not everybody else might be.
I can imagine that there are people that do want to insert more than one paragraph into one table cell and for this use case, having the possibility to insert p-tags into cells would be crucial.

However - do you actually know why browsers simply do not render empty paragraphs within htmlarea? From an outside view and theoretically spoken, it would be generally nice if there was no need to insert [AND]nbsp; into some content database just for an RTE to stay usable... this affects p-tags not within tables as well.
