Submit button not throwing error

Question

I have a Search Region and a table to show the data based on Search criteria...After search I am modifying the some fields with invalid data in Result table
and I am clicking the Submit button, it is throwing error(I written Exception in EO level) , the same time if i click the submit button second time , it is not validating and throwing the error and record is saving to database with invalid data.
Could you please help me and let me know what I am missing here?

Answer 1

I written the following code in EntityExpert, the EntityExpert code in EO
public boolean isItemNameValid(String ItemName)
System.out.println("Entity Expert");
System.out.println(ItemName);
boolean isActive = false;
ItemNameVVOImpl ItemNameVO = (ItemNameVVOImpl)findValidationViewObject("ItemNameVVO1");
ItemNameVO.initQuery(ItemName);
if (ItemNameVO.hasNext())
isActive = true;
System.out.println("Return ");
System.out.println(isActive);
return isActive;
and I am calling the above method in EOImpl
public void setItemName(String value)
if ((value != null) || (!("".equals(value.trim()))))
ItemNameEntityExpert expert = getItemNameEntityExpert(getOADBTransaction());
if (!(expert.isItemNameValid(value)))
throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
getEntityDef().getFullName(), // EO name
getPrimaryKey(), // EO PK
"Item Name", // Attribute Name
value, // Attribute value
"MSC", // Message product short name
"UPDATE_SUPPLY_ITEMNAME"); // Message name
setAttributeInternal(ITEMNAME, value);
Please check.
