Getting field values of more than one data source when calling a menu item

When a form has called another form (the user has opened a form by clicking a button in another form), you sometimes need to get information from the calling form.

The traditional way is to use element.args().record(); but this construction only allows for transferring ONE datasource at a time.

Sometimes it would be nice to be able to transfer more than one datasource.
This is an example of how that can be done.

The code must be implemented in the

init

-method of the CALLED form:

SysSetupFormRun s;
APMObjectTable apmObjectTable;
int dataSourceNo;

// Determine value of fields APMProductId and APMModelId of APMObjectTable record
// which might have been active at the time of pressing CTRL+F4 in the previous form
// (CTRL+F4 on model field in form APMCustOverview)
s = element.args().caller();
if (s)
{
    for (datasourceNo = 1; dataSourceNo <= s.dataSourceCount(); dataSourceNo++)
    {
        if (s.dataSource(dataSourceNo).cursor().TableId == tableNum(APMObjectTable))
        {
            apmObjectTable = s.dataSource(dataSourceNo).cursor();
            break;
        }
    }
}

Suppressing the infolog

Supressing the infolog is often useful in D365FO when augmenting code. When augmenting code using COC (Chain Of Command), you can have new code run either before or after the code you are augmenting. This means that any infolog-messages that the standard application code does, will be shown to the user, even if your augmentation supports a scenario where there must be no infolog-messages. How do you avoid the standard application infolog-messages ? To the rescue comes temporary supression of the infolog. The suppression consists of: 1) Saving the current infologLevel 2) Setting the infologLevel to SysInfologLevel::None 3) Run your code 4) Restoring the saved infologLevel to the infolog For example a table could have a validatewrite-method that validates that you are only allowed to use 3 out of 6 options in an enum-field, and you need to allow for a fourth one. Table a - validateWrite method: boolean validateWrite() {     Switch (this.enumField)     {     ...

Indicating mandatory field in a dialog (RunBase) class.

A classical problem is indicating that a field is mandatory in a dialog, when the field is not bound to a datasource/field in a datasource. Normally fellow developers will tell you that, that is not possible. I found a way to do this. In your Runbase-based class you can implement the putToDialog-method e.g like this: protected void putToDialog() { super(); fieldMask.fieldControl().mandatory(true); } where fieldMask is a DialogField object in your dialog. This will make the field act like it was a mandatory field from a datasource in a form, showing a red-wavy line under the field, and requiring the field to have a value. Attention: Your class has to run on the client.If you set your class to run on the server, you get a run-time error, when the fieldMask.FieldControl()-call is made.

Dynamics AX 2012 ValidTimeState tables and form changing view from current to all

Valid Time State tables are new i AX 2012 a gives the developer the possibility to easily create tables that hold e.g. current setup data for various purposes, and at the same time keeping a "history" of the changes of the data in the table. For more reading: http://msdn.microsoft.com/en-us/library/gg861781.aspx I was tasked with doing a setup table with rates for calculating Vendor Bonus and I chose to base this a valid time state table. The customer asked for a button on the form, where you maintain the vendor bonus calculation setup data, so you could toggle viewing "Current setup" or "All setup" records (changing the view from actual to all records and vice versa in the form). I found that you can not change the ValidTimeStateAutoQuery property on the form data source in a form at run-time. It simply does not change anything, so I came up with the following solution: A boolean class member in the classdeclation method of the form: boolean ...
