Access unbound form control from display method of form extension

Hi All.

I have requirement to display new field Settlement id from LedgerTransSettlement on LedgerTransAccount form Overview tab depends on ShowOpen checkbox of this form. If checkBox is selected, the value in settle id should be empty, otherwise, LedgerTransSettlement.SettleId.

I have added class extenstension:

[ExtensionOf(formStr(LedgerTransAccount))]
final class LedgerTransAccount_FRM_Extension
{
    [SysClientCacheDataMethodAttribute(true)]
    public static display Num settleId(GeneralJournalAccountEntry _generalJournalAccountEntry)
    {
        return LedgerTransSettlement::findTransRecId(_generalJournalAccountEntry.RecId).SettleId;
    }
}

Also i have created form extension and added new string control Settle id with next properties:
Data Source: GeneralJournalAccountEntry

Data Method: LedgerTransAccount_FRM_Extension::settleId

It works ok, but the next step is how to get value of form CheckBox control in display method? I could not find solution for this approach.

Also i have tried another approach:

[ExtensionOf(formStr(LedgerTransAccount))]
final class LedgerTransAccount_FRM_Extension
{
[DataSource]
    class GeneralJournalAccountEntry
    {
         public display Num SettleId(GeneralJournalAccountEntry _generalJournalAccountEntry)
        {
            LedgerTransSettlement ledgerTransSettlement = LedgerTransSettlement::findTransRecId(_generalJournalAccountEntry.RecId);
            
            if (showOpen.value())
            {
                return '';
            }
        
            return ledgerTransSettlement.SettleId;
        }
    }
}

But in this case what should be specified on form control property value for Data Method? If i just specify Data Method: settleId, i got the next error:

The data method 'settleId' was not found on the data source 'GeneralJournalAccountEntry' or its base table/view.

It makes me crazy, please help me to find right solution or approach.

RE: Access unbound form control from display method of form extension

- Is there a special reason why you want so? Why you cannot create a method in the extension class of the table?

If you tell me how it is possible to display data in the table's diaplay method that is selected by 2 criteria from 2 different tables, I will be very grateful to you.

By default, we send the write method to the displays and, based on the data in this record, we make a selection. Here you need to actually send the values from 2 tables.

- Have you tried to debug the display method? what if you return the hard coded value such as Return True;

the method will simply return the true

Hi Oleg Resh,

Well, of course, I know that need to use the edit method.

If you want to use EditDisply method, Please create a EditDisplay method rather than a display method.

The display was shown for an example, and it also does not work.

Have you tried to debug the display method? what if you return the hard coded value such as Return True;

Those links that you gave are all methods on the table, but I need methods on DS in the extended form class

Your method is not a EditDisplay method. It seems more like a display method.

Please have a look at next post to see how you can code a display method in two different ways.

And if you want to use EditDisply method, you would use either two or three parameters, not 1.

RE: Access unbound form control from display method of form extension

In PU15, it became possible to assign display / edit methods to an extension.

To experiment in the extended form class added the following method:

public display boolean haveGroupRows(PdsBatchAttribByAttribGroup _groupLine = PdsBatchAttribByAttribGroup)

{

PdsBatchAttribGroupSalesLineM attSalesLines;

;

info('1');

select firstOnly attSalesLines

where attSalesLines.SalesLineRecId == salesLine.RecId

&& attSalesLines.PdsBatchAttribGroupId == _groupLine.PdsBatchAttribGroupId

&& attSalesLines.PdsBatchAttribId == _groupLine.PdsBatchAttribAttribId;

If (attSalesLines)

return true;

else

return false;

Created a control and write a new method in the properties.
Does not work

}

RE: Access unbound form control from display method of form extension

In principle, you understood correctly, but there is one nuance, the general data structure is displayed by attribute groups and attributes, it will be the same for all order lines, i.e. the user does not create new lines, but simply selects by putting a flag on the necessary attributes. It is this functionality of putting a flag and I wanted to do it through the edit method.

Corrected the form and added checkBox, in which the selection should occur

RE: Access unbound form control from display method of form extension

I failed myself again to understand the problem.

I can understand the process that you have described in your recent reply with the help of a screenshot, which shows that for each sales lines you have a selected attribute-group and further based selected attribute-group there are multiple attributes (within a single attribute). Cool, so far.

However it does not mentions what the problem is?

If I look again at your original post, you have shown us a display method from AX2012. It is difficult for me to understand about the problem that comes while to try to replicate same method in AX7.

Please help us, if you want us to help you. Also you may want to create a new thread please.

RE: Access unbound form control from display method of form extension

I do not agree that the problem is in the relationship between the tables.

Maybe I have not quite clearly described. I will try again:

We have a table of groups of Batch (pdsBatchAttribGroup), each group has attributes (PdsBatchAttribByAttribGroup).

It is necessary for the sales line to determine which attributes are key for this order, and accordingly parties will be selected based on this choice.

To simplify the selection, I created on the form the sales lines (SalesTable) tree batch group list and the attributes list, where the user chooses which attributes he needs.

Accordingly, on the same form, you must see which attributes are already selected.

Sampling and displaying and I could make it through the edit method

Hi Oleg Resh,

Your problem sounds more like a relationships between the tables and not about display methods.

Can you please open a new thread and providing details of your problem in the new thread.

RE: Access unbound form control from display method of form extension

Hi, All!

And yet, how could this problem be solved?
For example, I need on the form SalesTable to display the data from GroupSalesLines. At the same time, a sample of data from group rows goes by a composite key: RecId of the sales line and GroupId from GroupTable.

Accordingly, in the displace method, you need to give 2 tables SaleLine and GroupTable

Lets imagine in ax 2012 it can looks like this:

display boolean haveGroupRows(GroupLine _groupLine)

{

GroupSalesLines groupSalesLines;

;

select firstOnly groupSalesLines

where groupSalesLines.SalesRecId == salesLine.RecId

&& groupSalesLines.GroupId == _groupLine.GroupId

&& groupSalesLines.AttribId == _groupLine.AttribId;

If (groupSalesLines)

return true;

else

return false;

}

that is, it is necessary on the form of order lines to display a list of groups and their attributes, and opposite each attribute to display a mark that this attribute is included for a given line or not.
