TYPO3 Core

Hi,

I also reproduced the error in the backend when some page content elements are in a workspace.

To provide a more hopefully general solution for this problem, I tried to fix the method getSpriteIconForRecord in the file t3lib/class.t3lib_iconworks.php since this seems to be the cause for this error.

Current code:
public static function getSpriteIconForRecord($table, array $row, array $options = array()) {
// Code of the method
}

Possible new code:
public static function getSpriteIconForRecord($table, $row, $options = array()) {
if (!is_array($row) || count($row) < 1){
return '';
}
// Code of the method
}

1. Remove the array in front of the parameter $row since this forces the caller to provide an array. As I counted ca. 87 usages of this method, it is easier to do this.

2. do the check, if the given parameter $row is really an array and if it has any elements.

Please note:
These checks may not fix all issues...

Looks like it's related to #25409, probably comes from deleted elements

@Michael mind pushing a patch to gerrit?

What is the reason the the pages_language_overlay record for that language is empty? Using an empty array is just masking the actual problem and not a real solution.

This bug is also affecting the filter function in the page tree when working in a draft workspace.

Can't reproduce this issue in current master (6.2).

It would be nice if we can get response from the users if the patch from #21084 fixes this problem here.
