Hi,

Seems we have a bug there...  please file a JIRA issue and we would address
it as soon as we can.

Otherwise, since 2.25 on we have introduced support to filter events based
on data element values. You can play around with columns of the event grid
in event capture app to see the request url sent to server. Below is an
example

https://play.dhis2.org/dev/api/28/events/query.json?orgUnit=DiszpKrYNg8&programStage=Zj7UnCAulEk&;
filter=qrur9Dvnyt5:GT:10:LT:100
&dataElement=qrur9Dvnyt5,S33cRBsnXPo,fWIAEtYVEGk,K6uUAvq500H&order=lastUpdated:desc&pageSize=50&page=1&totalPages=true

It goes by something like

*api/events/query?filter=DATAELEMENT_UID:OPERATOR:VALUE*

*api/events/query?filter=DATAELEMENT_UID:EQ:NULL*

Unfortunately, we have a bug  in handling NULL as part of the query
parameter.
