I have two DateTime fields in a hidden tab. I need to do some calculations on them in the onload handler when both are populated, but one always returns null when I call getAttribute() on it, even though I know it is on the page and has data.
alert("billingdatetime " + Xrm.Page.getAttribute("new_billingdatetime")); // prints "billingdatetime null"
alert("authorizeddatetime " + Xrm.Page.getAttribute("new_authorizeddatetime")); // prints "authorizeddatetime [Object object]"
Both fields are set up identically in the entity, and both are set up identically on the form as well. Both are visible and NOT read-only, and both are on the same hidden tab. It doesn't matter if the tab is hidden or not. However, the billingdatetime field
is NOT editable. It doesn't even get the grey box outline on mouseover that other read-only fields still get.
I don't understand what is going on here.
