TYPO3 Core

The nbsp is not visible in the ticket, sorry. Here again.

<table class="contenttable">
<tbody>
<tr>
<td>
<p>List</p>
</td>
<td>
((nbsp is inserted here))
<ol>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
</ol>
((nbsp and heir))
</td>
</tr>
</tbody>

Just run into the same issue with TYPO3 8.7 and PHP 7.1. Any workaround or fix would be appreciated.

After some digging in the TS object browser we figured the following lines of TS setup solved the issue for us:

lib.parseFunc_RTE.nonTypoTagStdWrap.encapsLines.innerStdWrap_all.ifBlank >
lib.parseFunc_RTE.nonTypoTagStdWrap.encapsLines.innerStdWrap_all.ifBlank =

We're still testing if this breaks anything other than purposely removing the

 

<ol>

<ul>

Same Problem here (TYPO3 8.7 latest version). The two lines from Oliver fixed the problems. No side effects until now, if i find some i will post.

maybe this explains the intention?

Reverted due to a regression https://forge.typo3.org/issues/83795

In the database it looks like this after saving (insert table, insert list, save):

<td>{space}{tab}{tab}{tab}<ol>{space}{tab}{tab}{tab}{tab}<li>1. eins</li>{space}{tab}{tab}{tab}{tab}<li>2. zwei</li>{space}{tab}{tab}{tab}</ol>{space}{tab}{tab}{tab}</td>

{space} and {tab} to make it clear... :-) - normal intended html structure

if you remove all the tabs and spaces directly in the database and reload the frontend - the &nbsp; are away...

If you remove the spaces between td and ol (and /ol /td) in rte (source view) and save then the spaces are not there in the database and also the &nbsp; are away. But if you reopen the content in rte again -> the tabs are there again (with all the problems when saving)

This also happens with

<td>&nbsp;<div>foobar</div>&nbsp;</td>

but not with

<td><a href="/">Start</a></td>

I guess that block elements inside a td-pair will be structured and therefore get some tabs/spaces around. Theese should not be converted to &nbsp; in the frontend.

Hope this will help other people to find a solution.

we use the following 2 lines. This avoids the nbsp; around <ol> and <ul> within a <td>, but still keeps the <p>nbsp;</p> intact.
