TCA columnsOverrides ignores default value
Defining a differnet default value for a field in the 'types' array doesn't work.
For example it would be useful to set the default frame for a content element of type gridelement_pi1 to none. To do so the TCA might be overriden as following:
$columnsOverrides = ; $columnsOverrides['frame_class']['config'] = [ 'default' => 'none', ]; $GLOBALS['TCA']['tt_content']['types']['gridelements_pi1'] = array_merge( $GLOBALS['TCA']['tt_content']['types']['gridelements_pi1'], ['columnsOverrides' => $columnsOverrides] );

- Subject changed from TCA columnsOverrides default to TCA columnsOverrides ignores default value
- PHP Version set to 7.2
I have the same problem. I've defined the field `author` in tt_content table:
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addTCAcolumns( 'tt_content', [ 'author' => [ 'config' => [ 'type' => 'input', 'size' => 30, ], 'exclude' => '1', 'label' => 'Autor', ], ] );
I added this field to my own CE 'myext_quotation'.
When I add 'default' => 'Test' into the `addTCAcolumns`, it is perfectly working with my CE.
But now I override the filed for my CE `myext_quotation` like this:
$GLOBALS['TCA']['tt_content']['types']['myext_quotation'] = [ 'columnsOverrides' => [ 'author' => [ 'config' => [ 'type' => 'input', 'default' => 'Hallo', ], ], ], ];
When I now add a new element of this Type, the field has the value of the 'addTCAcolumns' block.
If i leave the default value initially empty and then override the filed it gets ignored.

Same Issue for suggest wizard: #76661
There is already a patch attached. This should be the same in this case. There is a small piece of code missing, which merges the arrays.
I guess someone only has to find the accordingly place, we then could refactor the patch to provide a new method to merge the columnsOverrides and use this new method.
For Content Element Wizard, the default Value can already be added. See: https://docs.typo3.org/typo3cms/TSconfigReference/PageTsconfig/Mod.html#newcontentelement-wizarditems it's mod.wizards.newContentElement.wizardItems.[group].elements.[name].tt_content_defValues.
I'm not sure when default from TCA is applied, is it also applied if one changes the CType? Or is a field unchanged in that case? If so, it doesn't make sense to use default for tt_content depending on type I guess.

The value for the backend form field is set in backend/Classes/Form/Container/SingleFieldContainer
Even if $parameterArray['fieldConf']['config']['default'] contains the correct value (including columnsOverrides), the defined default value for the fields comes from $this->data['databaseRow'][$fieldName]. But this data depends on the processing within backend/Classes/Form/FormDataProvider
which a defined in ['formEngine']['formDataGroup']['tcaDatabaseRecord'] within the DefaultConfiguration
"DatabaseRowDefaultValues" sets the value. But the issue here is, that the "TcaColumnsOverrides" comes after "DatabaseRowDefaultValues".
I've tried simply changing the dependency, so that "DatabaseRowDefaultValues" depends on "TcaColumnsOverrides", but it didn't worked out. I run into a dependency cycle exception.
I currently have no clue how to resolve this dependency hell. :-/
