Grid Elements

The problem is that if you use workspaces there are placeholder elements inserted into tt_content to which the new elements with pid = -1 refer to.

The t3lib_tcemain creates a placeholder containing the default values of the original tt_content table layout.
Because gridelements alters this table and adds columns, these additional columns are ignored by the placeholder generation.

This can easily be fixed by moving a single line in class.t3lib_tcemain.php:661 to 655.

Line 656 onward:

if ($createNewVersion) {
    $newVersion_placeholderFieldArray = $fieldArray;
}

// Processing of all fields in incomingFieldArray and setting them in $fieldArray
$fieldArray = $this->fillInFieldArray($table, $id, $fieldArray, $incomingFieldArray, $theRealPid, $status, $tscPID);

needs to be changed to:

// Processing of all fields in incomingFieldArray and setting them in $fieldArray
$fieldArray = $this->fillInFieldArray($table, $id, $fieldArray, $incomingFieldArray, $theRealPid, $status, $tscPID);

if ($createNewVersion) {
    $newVersion_placeholderFieldArray = $fieldArray;
}

If you switch these lines, than the placeholder will contain the same configuration values for the tx_* columns and every other extension column added to the tt_content table.

Any update on this ?

We ran across this problem on a project and can't find any real solution for the problem. The above fix modifies typo3 core so we can't use this way, as it may cause some sideeffects on other things. some versions below class.t3lib_tcemain.php:700 to 704 is a hook processDatamap_postProcessFieldArray which is already implemented in class.tx_gridelements_tcemainhook.php. is it maybe possible to use this function instead of modifying the core ?
