Hi Experts,

How to identify caller form in AX7.

For e.g. Serial number dimension field is available in many forms like Inventory transfer journal, Movement journal, Purchase order form etc.

When we click on Serial number, system will open a form (InventSerialLookup).

Is there any possibility to identify from which form InventSerialLookup is called?

Thanks,

N.Sridhar

Just use find references to see from where it is called

Hi Sukrut,

When we click on Serial number, system will open a form (InventSerialLookup). Based on from which form the Serial number is clicked, I have to perform some action.

Basically, I have to identity the caller form at run time and perform some action based on that.

In AX 2012 in the init method of the form , we will use element.args().caller();

I am asking for similar kind in AX 7.

Thanks,

N.Sridhar

element.args().caller() is still available in AX 7. You should tell us what problem you have with it.

By the way, is checking the caller name really a good design? What business problem are you trying to address by this technical solution?

Hi Martin,

Requirement is to create multiple transfer journal lines for the multiple serial numbers selected.

OOB AX does allow to select only one serial number; but, we have customized to select multiple serial numbers by setting multiselection property to true and showRowlabel property to true.

Multipleselection of serial number should work only when InventSerialLookup is opened from Inventory transfer journal form.

Thanks,

N.Sridhar

Sorry, I don't see the explanation of your problem with element.args().caller().

Alternative designs include using a different lookup form from "Inventory transfer journal form" and passing a parameters from there which you would check in InventSerialLookup (regardless of which form set this parameter, therefore you wouldn't have a hard dependency on a particular form name).

Hi Martin,

I am enabling the multiselect property of the grid in InventSerialIdLookup form; and enabling this only when the form is opened from InventJournalTransfer and PurchTable.

Below code has done the trick.

[PostHandlerFor(formStr(InventSerialIdLookup), formMethodStr(InventSerialIdLookup, init))] public static void InventSerialIdLookup_Post_init(XppPrePostArgs args) { FormRun element = args.getThis(); FormRun callerForm = element.args().caller(); FormGridControl gridInventSerial = element.design(0).controlName('GridInventSerial'); FormGridControl gridItem = element.design(0).controlName('GridItem'); FormGridControl grid = element.design(0).controlName('Grid'); str callerFormName; callerFormName = element.args().caller().name(); if(callerFormName == formStr(InventJournalTransfer) || callerFormName == formStr(PurchTable)) { gridInventSerial.multiSelect(true); gridInventSerial.showRowLabels(true); gridItem.multiSelect(true); gridItem.showRowLabels(true); grid.multiSelect(true); grid.showRowLabels(true); } }

Hi Shridharan,

Somehow same logic is not able to work in my case, as I am getting some error for fetching the callername.

Below is the piece of code,

/// <summary>
///
/// </summary>
/// <param name="args"></param>
[PostHandlerFor(formStr(PurchCreateOrder), formMethodStr(PurchCreateOrder, init))]
public static void PurchCreateOrder_Post_init(XppPrePostArgs args)
{
FormRun element = args.getThis();
FormRun callerForm = element.args().caller();
str callerFormName;

callerFormName = element.args().caller().name();

if(callerFormName == formStr(PurchTable))
info('From PurchTable');
else if(callerFormName == formStr(SalesTable))
info('From SalesTable');
}

It is throwing error for the line which is marked in red.

Unable to cast object of type 'Dynamics.AX.Application.PurchTable' to type 'Dynamics.AX.Application.PurchPrepayTable'. Less than a minute ago

Kindly guide me I am already stuck with this small requirement of fetching callerform name in 365FO.

Are you sure that's the line of code that throws the error?

Anyway you should replace that line with

callerFormName = callerForm.name();

But to me it looks like your error is coming from somewhere else, since you don't have any casting to any table in this piece of code.

Yes it seems correct to me as well.

I think it is the version Platform Update 12 which is not allowing me to use such piece of code.
