CPM – recalculate attribute from model after form load

[nexj uae]

(: onServer ‘(value)) is not working. this is getting called only at form creation or reseed.
We have the below code for getting the approval history in to form.
(: onServer ‘(value enabled)) – this is recalculating enabled property , but not value.

(bp:page
Submit
(: caption “Submit the Changes”)
(bp:section
cddApprovalHistory
;(: visible #f)
(bp:textarea
approvalHistory_Text
(: caption “Approval History”)
(: enabled (refreshEditibility (@ question relObjectId)))
(: value (getApprovalHistory (@ question relObjectId)))
(: onServer ‘(value enabled))
(: sync #f)
)
)
)

cddLibrary.scm

(define (getApprovalHistory inst)
(let*
(
(extHistoryColl
(enbd:TransactionExceptionExternalHistory’read
‘()
`(= (@ serviceRequest enbdCDD) ,(string->oid inst))
‘((enbdEndDateTime . #f))
‘()
‘()
‘()
)
)
(strApprovalHistory “”)
)
(unless (extHistoryColl’empty)
(for-each
(lambda (extHistoryInst)
(set! strApprovalHistory
(string-affix
(string-append
“Name of Approver: ”
(extHistoryInst’enbdFullName)
“; Designation: ”
(extHistoryInst’enbdWorkedBy)
“; Date & Time: ”
(string-collection-affix
“-”
(unless (null? (extHistoryInst’enbdStartDateTime))
(number->string (date-part ‘day (extHistoryInst’enbdStartDateTime)))
)
(unless (null? (extHistoryInst’enbdStartDateTime))
(number->string (date-part ‘month (extHistoryInst’enbdStartDateTime)))
)
(unless (null? (extHistoryInst’enbdStartDateTime))
(number->string (date-part ‘year (extHistoryInst’enbdStartDateTime)))
)
)
)
“\r\n\n”
strApprovalHistory
)
)
)
extHistoryColl
)
;return
strApprovalHistory
)
)
)

different properties recalculate on different conditions.

enabled property recalculates on form launch and on dependency updates.

value property recalculates on initial form launch, and on dependency updates. e.g. when a dependent value (e.g. (@ question q1)) changes value.

note, value property does not recalculate on form refresh for performance reasons.
