TYPO3 Core

I can see this behavior only in flux fields from the fluidtypo3 extension as stated here https://github.com/FluidTYPO3/flux/issues/1388.

When using a RTE-field configured by a flexform in a regular extbase-plugin this behavior wont show up. still have to check if the config finally gets loaded with 8.7 or if this is still buggy but thats another issue.

kind regards

This happens in an custom form element using only core functionality.

You can grab following extension https://github.com/r3h6/TYPO3.EXT.form_confirmation_finisher and activate the rte in the yaml configuration.

Then on the form content element you can observe the behavior.

I can confirm this issue with powermail plugin flexform fields (TYPO3 8.7.1)

I can also confirm this issue in Powermail

We had this issue mainly with DCE fields that has a RTE editor.

The following configuration in the RTE field solved it:

<config>
  <enableRichtext>1</enableRichtext>
</config>

Maybe this should somehow be solved by the core to avoid "broken functionality" in "random" places upon upgrading.

I can confirm the problem when adding CKeditor to a Gridelement via Flexform.

This code produces empty paragraphs on saving:

<?xml version="1.0" encoding="UTF-8"?>
<T3DataStructure>
    <meta>
        <langDisable>0</langDisable>
    </meta>
    <ROOT type="array">
        <type>array</type>
        <el type="array">
            <text>
                <TCEforms type="array">
                    <config type="array">
                        <type>text</type>
                        <cols>48</cols>
                        <rows>5</rows>
                    </config>
                    <label>Text</label>
                    <defaultExtras>richtext[*]:rte_transform[flag=rte_enabled]</defaultExtras>
                </TCEforms>
            </text>
        </el>
    </ROOT>
</T3DataStructure>

BUT... the solution from Lars Houmark seems to solve it

<?xml version="1.0" encoding="UTF-8"?>
<T3DataStructure>
    <meta>
        <langDisable>0</langDisable>
    </meta>
    <ROOT type="array">
        <type>array</type>
        <el type="array">
            <text>
                <TCEforms type="array">
                    <config type="array">
                        <type>text</type>
                        <cols>48</cols>
                        <rows>5</rows>
                        <enableRichtext>1</enableRichtext>
                    </config>
                    <label>Text</label>
                    <defaultExtras>richtext[*]:rte_transform[flag=rte_enabled]</defaultExtras>
                </TCEforms>
            </text>
        </el>
    </ROOT>
</T3DataStructure>

Insert the config

<enableRichtext>1</enableRichtext>

This also and definitely happens under typo3 8.7.10 with dce 1.5.2:

text</p><p>more text

becomes:

text</p>
<p>&nbsp;</p>
<p>more text

or:

text</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>more text

Rah.
Just found while trying for a second time that the solution for dce also works here (i wondered why it wouldn't first, but it does):

<enableRichtext>1</enableRichtext>

inside typo3conf/ext/gridelements/Configuration/FlexForms/default_flexform_configuration.xml

I also found that bug in a current project, using 8.7.19.

Current case: I have a custom TCA for use in IRRE with a type and a field "bodytext" that has no configured RTE by default. In some other TCA I use that IRRE foo and enable the RTE by using columnsOverrides.
If I enable the RTE by default, the issue disappears. It seems something goes wrong with columnsOverrides/irre_foo/config/overrideChildTca/columns/bodytext/config/enableRichtext = true

Adding `<enableRichtext>1</enableRichtext>` doesn't solve the problem for me at a plugins flexform field in 8.7.13.

...and even in 9.5.4 this isn't solved yet.

I found out that the issue is related to flexforms, having RTE in a sheet. When a field is not in a specific sheet (that is sDEF, as the example shows from above), all works fine.

Please please review this patch for sheets as well @Jan Schröder Kornblum, could you upload your demo extension to have people test this?

We experienced the same bug in TYPO3 8.7 with gridelements (gridelement with an RTE) and CK editor. In our case the problem is not the bug found here, it's gridelements. You can find the issue here (https://gitlab.com/coderscare/gridelements/issues/46) including a patch.

Unfortunately, I'm still facing with this bug in Typo3 v 9.5.9 (it works fine in version 8), so I just want to know if the patch has been included in Typo3 9.5.9 as well.

Analyzing my DataHandler.php file, it seems to be the case, but once again using Typo3 9.5.9 and CKE I get these empty lines in FE.

I'm not using extension like "flux", however, grid and DCE extensions are used.

Thaks in advance for your reply.
