[sw-discussion] problem about undo of header and footer

[lijian]

Hi Mathias,

I found an undo problem when the header or footer is changed.
For example:
First, I do some operations on a document(now there is no header or footer) 
when the UNDO button is lighted;
Second, I insert the header or footer to the document. Then, the UNDO and REDO 
button is grey and I can't 
undo any of the operations before.
I think this is unreasonable.

I found the codes in sw/source/core/doc/docdesc.cxx like this:

// #i46909# no undo if header or footer changed
if( bHeaderFooterChanged )
    {
        ClearRedo();
        DelAllUndoObj();
    }

This is to make undo and redo grey if header or footer is changed.
The codes above is to solve issue 46909. After tracking on issuezilla, I found 
there are a few crash problems with undo of
header and footer before, so engineers of the community accepted this solution 
for the moment ?

So, that means we should just remove all the undo operations when header or 
footer is changed ?
Should it be this ?

I need your help.Thank you!

Best wishes,
