What I had in mind was (using your example) :
SelectQuery selQueryTab1 = new SelectQuery("Tab1");
DataObjectList dataObjectsInTab1 = new DataObjectList(dataContext
.performQuery(selQueryInterface));
int nSize = dataObjectsInTab1.size();
for(int i=0; i<nSize; i++)
{
dataObjectTab1 = (Tab1) dataObjectsInTab1.get(i)
dataObjectTab2 = (Tab2) dataContext.createAndRegisterNewObject
("Tab2");
//here copy data from dataObjectTab1 into dataObjectTab2
ValidationResult validationResult = new ValidationResult();
dataObjectTab2.validateForSave(validationResult);
if (validationResult.hasFailures()) {
//log failures
}
}
dataContext.setValidatingObjectsOnCommit(false);
dataContext.commitChanges();
Remember that in your "Tab2" object you can override validateForSave
(...) method to add more validation rules to your object. (dont
forget to call super.validateForSave(...) otherwise you might get
unexpected results)
