AX2012 Form Code Upgrade error

(0) ShareShare
ReportReport
Posted on by lispyj 110

I am upgrading the code for a custom form from AX2009 to AX2012 R3.  I receive the following error on the init method of the ShipCarrierTracking datasource.

"The assignment is invalid because the variable shipCarrierTracking is read only"

The line of code:

shipCarrierTracking = element.args().record();

Can anyone tell me what is up?

The entire method:

public void init()

{

Query query;

QueryBuildDataSource qbds;

;

if(element.args())

{

if(element.args().dataset() == tablenum(ShipCarrierTracking))

{

shipCarrierTracking = element.args().record();

query = new Query();

qbds = query.addDataSource(tablenum(ShipCarrierTracking));

qbds.addRange(fieldnum(ShipCarriertracking, PackingSlipId)).value(queryValue(shipCarrierTracking.PackingSlipId));

qbds.addRange(fieldnum(ShipCarrierTracking, SalesId)).value(queryValue(shipCarrierTracking.SalesId));

this.query(query);

}

}

super();

    Hi Lispyj

    Depending on what exactly you want to do you can use the following:

    shipCarrierTracking.data(element.args().record());

    The form itself just displays a ShipCarrierTracking record so that it can be edited as needed.  The error occurs when attempting to set the datasource record to equal the record in the buffer.  I wondered if the issue is related to AX2012 for Edit Mode changes.

    The code is in the init method of the ShipCarrierTracking datasource on the form. The datasource uses the ShipCarrierTracking table.  This code compiled and function correctly in AX2009.  To me is sounds like the ShipCarrierTracking table is somehow read only, but I don't know where that might be defined.

    Hi

    Without knowing a bit more behind the form, one may struggle to determine the issue. Where is ShipCarrierTracking variable declared in your 2012 form? Also Do you perhaps have a "ShipCarrierTracking" datasource on your new form?
