Thought I would weigh in on this one. godson: if I'm understanding you correctly, you do not already have an extra column in the database for 'totalFees'. Instead, you have a method called "getTotalFees" that returns you some derived value, correct? So you will actually never be setting a 'totalFees' column explicitly. If this is the case, you do not have to explicitly create a new database field if you don't want (or need) to. If you do this and annotate that field like you have, the getter is actually never called because the admin actually works off of reflection directly on the fields itself and does not use the getters/setters.

You can have derived fields be displayed in the admin (in our terminology we refer to these as 'non-persistent fields') if you actually want to display the result of a getter or any other method. I believe you can actually do this by simply adding @AdminPresentationOverrides to your class.

So, in your case, you would add something like this to the top of your OrderImpl subclass:

Just went looking through to code again to confirm a suspicion. This is only half of the story; the other half is the overrides you have to make in the admin code itself. This snippet is copy/pasted from the OrderListDataSourceFactory class that is included in BLC:



Notice this line here:


That second String[] parameter corresponds to nonPersistentFields that you want to add to the list of fields. In your specific case, you would change this line to the following:



With that change, now the admin will know to check for that field, and it will get the presentation attributes that you defined in the @AdminPresentationOverrides on the OrderImpl entity.

To give a small recap, you will create a new DataSourceFactory that looks like this:


Now, you have to associate this dataSourceFactory in an overridden OrderPresenter. Your overridden setup() method should look like this:



Notice that the second line of that method instantiates a new PBOrderListDataSOurceFactory.

Once you go through that, you should have what you want.

On our checkout page there is a field called Government fees that pulls data from our totalFees property in our custom order object that extends the broadleaf order object. The fees populate on the order checkout page, but it does not populate n broadleaf admin. I placed a log4j logging on the method, and it does get called when the order checkout page is rendered. The order checkout page and the broadleaf admin page is calling the same method, so the value should display in broadleaf admin. What am i missing?

Snapshot of code below:
@Column(name = "TOTAL_FEES")
@AdminPresentation(group = "Order", friendlyName = "Order Total Fees", order =20)
protected Money totalFees

@Override
public Money getTotalFees(){
Money feeTotal = new Money(BigDecimal.ZERO);
for (FulfillmentGroupFee fee : fg.getFulfillmentGroupFees()){
feeTotal = Moneyutil.nullSafeAddMoney(feeTotal, fee.getAmount());
}
return feeTotal;
}

Why do you need the column there if you are basing it off of the method? Remember, the admin does not normally work off of getters/setters but rather directly modifies the properties of the entity via reflection. Are you sure that you instantiated the DataSource in the DataSourceFactory correctly, and that you are passing in getTotalFees into the nonPersistentProperties parameter that I mentioned earlier?

Hi @phillipuniverse,

How to achieve this in latest code when you have PersistencePackageFactoryImpl class and this have the creation of persistenceperspective.

Thanks
