thanks heaps for this - I'm looking at your suggestions at the moment. will let you know when I've got something that compiles after the changes... :-)

Below is a list of recommendations/changes you need to incorporate so that code can function properly.

1. Create two different local variables for paging info, to be used by task and cases grid exclusively.

2. Query the database inside a with(). In other words, task and cases datasubset should be populated inside a with() block so that they can be reevaluated.

load(
local!taskPaging:a!pagingInfo(1,10),
local!casePaging:a!pagingInfo(1,10),
with(
/*taskPaging for Task data subset*/
local!taskDatasubset:a!queryEntity(entity:{},pagingInfo:local!taskPaging),
/*CasePaging for Case Data subset*/
local!caseDatasubset:a!queryEntity(entity:{},pagingInfo:local!casePaging),
/*Sample Grid Code*/
a!gridField(
label:"Tasks",
columns:{
a!gridTextColumns(
data:index(local!taskDatasubset.data,"taskName",{}))},
saveInto:local!taskPaging,
value:local!taskPaging)
))

3.The syntax for total count is incorrect, It should be like

if(
rule!APN_isEmpty(
index(local!dbTasks,"data","")
),
0,
index(
local!dbTasks,
"totalCount",
0
))

totalCount is an attribute of datasubset so "data.totalCount" is an incorrect expression. Though local!dbTasks.totalCount is correct.

Hi David!

The data is not coming in the grid because you are using the code as index(local!dbTasks,"caseNumber",{}). Here you need to change the syntax as -

index(
local!dbTasks.data,
"caseNumber",
{}
)

. Note the 'data' part contains the data inside a datasubset.
