AEM Touch UI component dialog checkboxes

aemTouchCheckboxDialog.xml

<!-- Checked checkbox will result in a String property of "true" -->
<myCheckbox
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/foundation/form/checkbox"
    text="My Checkbox"
    name="./myCheckbox"
    value="true"/>

<!-- Checked checkbox will result in a Boolean property of true-->
<myBooleanCheckbox
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/foundation/form/checkbox"
    text="My Boolean Checkbox"
    name="./myBooleanCheckbox"
    value="true"/>
<myBooleanCheckboxType
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/foundation/form/hidden"
    name="./myBooleanCheckbox@TypeHint"
    value="Boolean"/>

<!-- Checkbox defaults to checked and saves a Boolean value of true -->
<myCheckbox
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/foundation/form/checkbox"
    text="My Checkbox"
    name="./myCheckbox"
    value="true"
    checked="true"/>
<myCheckboxType
    jcr:primaryType="nt:unstructured"
    sling:resourceType="granite/ui/components/foundation/form/hidden"
    name="./myCheckbox@TypeHint"
    value="Boolean"/>

The uncheckedValue is working for me on AEM 6.5 inside of a granite/ui/components/coral/foundation/form/multifield. I'm using it to check whether to open a link in a new tab or not. This is what my dialog looks like for the field:

<newTab
	jcr:primaryType="nt:unstructured"
	sling:resourceType="granite/ui/components/coral/foundation/form/checkbox"
	text="Open link in new tab"
	name="./newTab"
	uncheckedValue="_self"
	value="_blank"
	checked="true"/>

Just be sure that uncheckedValue does not equal empty string as it won't be stored as a property (the property will just disappear from the node). AEM will check the checkbox if the property doesn't exist. For me this is what was causing the checkboxes to recheck themselves when I subsequently opened the dialog. Setting uncheckedValue with a value other than "" fixed the issue.
