<div class="">And the three possible values of [ true, false, null ] are mapped in the user interface into a checkbox for “Pre-populate Records?” : </div>
<div class=""><br class="">
</div>
<div class=""><img apple-inline="yes" id="BEFF4441-FE9E-4177-B6B5-C831CAC5A96B" height="324" width="640" apple-width="yes" apple-height="yes" src="cid:30149E97-505A-4445-A61E-F60C56E9F19B@Virginia.EDU" class=""></div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class=""><br class="">
</div>
<div class="">I’m guessing that part of the problem I’m having is that null and false are both represented by an unchecked box, and that null is ignored, but false isn’t in whatever operation and precedence determines the final computed value. i.e. sometimes
clicking that checkbox doesn’t have the effect of turning the operation on, and I don’t know quite how to distinguish false and null from the frontend interface, and I don’t know how those backend values map into the three different places to set the value.

<div class="">Some tips or guidance in figuring this out would be appreciated!</div>
