We have been using the Calc Macro Extension in xWiki 6.3 and it was working well. When we upgraded to 6.4.1, the macro stopped working and now displays: Failed to execute the [groovy] macro. Click on this message for details. Debugging the CalcGroovy script, it appears that when the script does a .getParent() on the MacroBlock that is coming in, it is returning null. Previously, it used to return the TableHeader block of the table containing the Macro. Is there something that needs to be changed in the CalcGroovy code to get it to work with 6.4.1, or is this something that will need to be fixed in 6.4.2?
