Hey again Georgi,
this seems like a bug with the d2:hasValue function. Using enrollment analytics, the intended outcome for d2:hasValue(#{programStageWithNoEvents.dataelement}) is false. Just making sure your program indcator was an enrollment program indicator - could you register this as a bug?

> We do not have a function that does exactly what you asked for, but hopefully we can find a way if we examine the data elements in your stages. Do the stages have a data element that is mandatory, or at least so pivotal that you can sue that data element to determine wether the event should be counted? If so I'd recommend looking at a program indicator with the analytics type enrollment. With this strategy you can make four program indicators that fullfills the explicit requirement for 1, 2, 3 and 4 stages:
> Just first stage:
> d2:hasValue(#{stage1.dataelement}) && !d2:hasValue(#{stage2.dataelement}) && !d2:hasValue(#{stage3.dataelement}) && !d2:hasValue(#{stage4.dataelement})
> Just first and second stage:
> d2:hasValue(#{stage1.dataelement}) && d2:hasValue(#{stage2.dataelement}) && !d2:hasValue(#{stage3.dataelement}) && !d2:hasValue(#{stage4.dataelement})
> ..and so on.
>  
> With the above strategy you would find every tracked entity that has followed the expected sequence of events. If you have any requirements for how to count the possible cases that deviates the normal(just stage 1 and 3 for example), the expressions might look different.
>  
> If there is no data element that you can use to proxy the presence of events, you will need a new function for checking events regardless of data. In that case, please report this as a Jira issue.
