I am using Linktourl and set the target as _self. When I click the link, it is always opening in a new window.
View source reveals 2 underscore in front of self i.e __self. Only for _blank, it is not padded with 2 underscores, for parent and top, 2 underscores are prefixed.
If I remove the underscore in the target property ie 'self', a single underscore is not padded.
I have deploed this in WAS 640 (EP7), is this a bug?
