TYPO3 Core

If I try to move a page (click/drag, cut/paste, use "move page") within a workspace, nothing happens after selecting a destination. A blank frame is displayed in the page area and the page has not moved.

I have attempted to move pages between different sections of the page tree without success. I have also ensured that all versions of any content have been removed from the workspace (logged in as Admin).

No warning errors are reported though until you enable them for PHP, this then shows...

Fatal error: Cannot re-assign $this in E:\htdocs\typo3_42\typo3conf\ext\static_info_tables\class.tx_staticinfotables_syslanguage.php on line 41

I am using workspaces heavily within my editor environment and cannot action page moves in our current stage version (4.1.1). I am testing 4.2.0beta1a in the hope this has been corrected as outlined in tracker ID 5560 (0005560: Typo3 doesn'f make a new version of page by cut,move,move-down,move-up by content-elements ).

I have followed the normal upgrade of 4.x to 4.2 and updated the database table structure via COMPARE
