Every time I select some of the elements of my p:datatable it always returns the first one, always.
I have this following piece of code that is used on my screen, in which the detailEntity is referenced in the table as a row of the same.
Tab Lots
<sgv:detailCrud

scrollHeight="350"
updateClass="lotChangeListener, .crudButtons"
controller="#{productLotsController}"
btnDetailDeleteLabel="#{productByLotsController.inNewMode or productLotsController.inNewMode ? productsBundle.deleteLabel : productsBundle.inactivateLabel}"
withDelete="#{productLotsController.showEntity and productLotsController.deletableEntity}"
disabled="#{not (productByLotsController.byLots and not productsController.inViewMode)}">

As you can see, I have a custom component that I created called sgv:detailCrud. He is responsible for owning the CRUD architecture of my services, being able to delete, create or view details of a line. (VIDEO DETAILS)

Another detail is that I can do these crud operations on the rows of the table without any problem, that is, hitting the index. However, I have this problem of always selecting the first row when I click my button to print a lot variation, it's like it doesn't obey the crud architecture for some bizarre reason...
I believe this problem is only for the view, but for the sake of conscience I will post the code of the two controllers of this button here too, follow the thread.
Method that should take the selected entity in the table and assemble it from the String Builder
public String getTypePrintedProductLot(ProductLot selectedLot) {
if (selectedLot != null && selectedLot instanceof ProductLot) {
final Optional<ProductLabelSetting> optional = this.productLabelSettingsRepository.listActives().stream().findFirst();
if (optional.isPresent()) {
final StringBuilder builder = new StringBuilder();
final SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
final HashMap<String, Object> params = new HashMap<String, Object>();
final Logger log = LoggerFactory.getLogger(ProductLotsController.class);
log.warn("********** SELECTED LOT NUMBER IN TABLE **********\n");
log.warn(selectedLot.getNumber());
log.warn("********** SELECTED LOT NUMBER IN TABLE **********\n");
params.put("product", selectedLot);
final ProductLot lot = selectedLot;
params.put("lot", lot);
if (lot.getExpirationData() instanceof PerishableExpirationData) {
params.put("lotExpiration", sdf.format(lot.getExpirationData().getExpiration()));
} else {
params.put("lotExpiration", "Não Perecível");
}
params.put("login", this.currentUser.getLogin().toUpperCase());
params.put("enterprise", this.currentEnterprise.getName().toUpperCase());
builder.append(optional.get().parser(params));
return builder.toString();
}
}
return null;
}
Controller that receives the values from the String Builder and prints the variation according to this information
