Hi, i found another work araround for this isse.
My problem was that the client didn't like/sometimes forgot to switch panel to see if the checkbox was checked or not.
So i changed the property to a dropdown with True|False alternatives.
This way you can read the same value as checkbox sets, but as a dropdown.
- Not the best way to show a boolean but at least it works :-)
<xmp_property name="check" category="external" label="$$$/Custom/Property/Check=Checked or not:" type="closedchoice">
<xmp_choice raw_value="" label="$$$/Custom/Property/BooleanTrue=Select"/>
<xmp_choice raw_value="True" label="$$$/Custom/Property/BooleanTrue=True"/>
<xmp_choice raw_value="False" label="$$$/Custom/Property//BooleanFalse=False"/>
</xmp_property>
