Multiple Errors in screen - acumatica

Question

Is it possible to display error in toolbar without using [PXProcessButton] and the delegate? I've overridden a Process Button in acumatica, but before it executes I have underlying codes to check a condition and fire an error if it find any.

Answer 1

There's not a lot of valid scenario where you have a PXProcessButton without a PXProcessing or PXFilteredProcessing data view. I would expect a PXButton to be used when there is no PXProcessing data view instead of a PXProcessButton.
With a PXProcessing view in the process screen you would do:
PXProcessing<DAC>.SetError(new PXException("Test));
There is no method that I know of that allows to directly set an error in the toolbar. You'll notice that these error are tied with a PXLongOperation. In the main toolbar you'll see the hourglass icon of the long operation and it can change to a success or error icon.
Process action does this but also Save action amongst others. Unless you require a long operation I would advise to avoid displaying error in the main toolbar because it's not a behavior found in the base Acumatica product.
That said you can replicate that functionality pretty much everywhere by throwing a PXExceptionfrom within a PXLongOperation inside an PXAction event handler like this:
public class SOOrderEntry_Extension : PXGraphExtension<SOOrderEntry>
{
public PXAction<SOOrder> test;
[PXUIField(DisplayName = "Test")]
[PXButton]
protected virtual IEnumerable Test(PXAdapter adapter)
{
PXLongOperation.StartOperation(Base, delegate {
throw new PXException("Test");
});
return adapter.Get();
}
}
