I am having a problem with conditionally displaying tabs inside a section in a form.
For the tab titles, I have ="Package ID - " & pv!reqPackageList[1].package_id and ="Package ID - " & pv!reqPackageList[2].package_id.
On the tab display, I have defined "Only show this tab when..." as =if(isnull(pv!reqPackageList),false(),if(isnull(pv!reqPackageList[1]), false(), true())) etc
But even when the reqPackageList is empty all the tabs get displayed with error. What am I doing wrong here?...

tried all combinations of null checks and indexes, not working. Anyone seen this issue before?

Hi,
You can add empty check along with null check in your condition. Your CDT is multiple so its better to check the length also.
You can try this rule
if(or(isnull(ri!givenValue),ri!givenValue=""),false(),if(length(ri!givenValue)=0,false(),true()))

If you want to show or hide the tabs depending whether the lists are empty or not, isnull() will not help you. Have you tried to using length()? Beware that length() does not like null values, so you might have to use both.

Yes length with null did the trick, thanks all.
