Steps to reproduce:
- go to Admin Section -> Edit Mode Settings -> Enable version summary . Set this to YES
- go to a page or create a page, and don't fill the Version Summary field.
- click Save and View
You will get a modal which forces you to write a summary. On IE8 and IE9, the modal windows already has the value of "undefined"
- this is inconsistent with Firefox Browsers, which have this field blank by default. And IMO this is the correct behavior
- we could use a xwiki type of modal, not a js one, but this is another issue.
