If you don't want the "Attribute" action to appear on the undo stack, enter a hidden undo context.

The document model does not support this function; this is something as basic as knowing how to use the API reference: - search getCurrentUndoActionTitle() in the general index: http://www.openoffice.org/api/docs/common/ref/index-files/index-7.html getCurrentUndoActionTitle() - function in interface ::com::sun::star::document:: .XUndoManager http://www.openoffice.org/api/docs/common/ref/com/sun/star/document/XUndoManager.html#getCurrentUndoActionTitle - this is a function of the XUndoManager interface, how do you access this interface from the document model? See the interface uses: http://www.openoffice.org/api/docs/common/ref/com/sun/star/document/XUndoManager-xref.html - the interface is used as return type of XUndoManagerSupplier::getUndoManager() - go to the uses of XUndoManagerSupplier http://www.openoffice.org/api/docs/common/ref/com/sun/star/document/XUndoManagerSupplier-xref.html The interface is supported by all services implementing the document models The document model implements XUndoManagerSupplier; use this interface to access the undo manager. getCurrentUndoActionTitle() is a function of the undo manager: the code without any check should be ThisComponent.getUndoManager().getCurrentUndoActionTitle() Regards -- Ariel Constenla-Haile La Plata, Argentina
