Undeclared Identifier: TWPMMInsertTextContents

When trying to access the MailMergeGetText procedure of a TWPRichText component I get 'Undeclared Identifier: TWPMMInsertTextContents' when compiling the project.

I have WPRTEDefs in the uses clause.

I'm using WPTools 7 v. 7.09 in Delphi XE4.

In WPTools 7 you also need WPRTEEdit.
