When I press the save button on options, OnInit() is the first method to be
called, but the productId is null.
*How can I make sure it gets the productId ??? *
The next method that is called is the
public boolean onSaveOptionFormTable() throws SystemException {
if (optionFormTable.getForm().isValid()) {
List<ProductOptionEnt> productOptions = optionFormTable.getRowList();
dashboardSBBeanLocal.saveProductOptions(productOptions);
}
Long id = Long.parseLong(idField1.getValue());
HashMap<String, String> m = new HashMap<String, String>();
m.put("productId", "" + id);
setRedirect(EditProduct.class, m);
return true;
}
but here the productOptions list is empty... cause of the null productId
from the OnInit() method.
The next method is then again the OnInit() method, and now there is a
productId.. cause the
m.put("productId", "" + id);
in onSaveOptionFormTable.
