I'm trying to modify LinkDialog.js under RTE to have the checkbox "Open in a new window" checked by default. According to the day API, it should just be adding the value "checked": true to the default values, but that doesn't work. It does accept my other value changes, such as the name, so I now the edits are coming through.
Here's the code I modified:
{
"itemId": "targetBlank",
"name": "targetBlank",
"xtype": "checkbox",
"boxLabel": CQ.I18n.getMessage("Open in new window"),
"checked": true,
"value": "targetBlank"
}
