I'm trying out the Write a simple Confluence Space Blueprint . I encountered a fatal error while creating it because it says this:

The whole page hangs and i need to reopen it ... finding out that the space gets created instead with asdq home sitting right there nicely.
If i change confluence.blueprints.space.example.home.title.suffix=Home Page then it works fine...no error popup.
Am i missing anything here??
spacebp.js
AJS.bind("blueprint.wizard-register.ready", function () {
function submitExampleSpace(e, state) {
state.pageData.ContentPageTitle = state.pageData.name + " " + AJS.I18n.getText("confluence.blueprints.space.example.home.title.suffix");
return Confluence.SpaceBlueprint.CommonWizardBindings.submit(e, state);
}
confluence-space-blueprints.properties
confluence.blueprints.space.example.home.title.suffix=Home
