Hi All,
Is that true? I read a comment somewhere which was saying that any uncaught
exception would cause Seam to close the opened connection (hence preventing the
next phases from accessing it...?)
I noticed that when adding a validation method to the input tag that queries
the database and afterwards throws an ValidationException if not valid. Then
the selectItems (on the same rerendered page) would try to execute a
entityquery.getResultList() which results in a transaction - closed
exception...
Did I interpret this correctly? If so, is there any way around it?
Any help or hint appreciated,
Tino
my xhtml:
| ...
| <q:field helpText="Please enter an alpha-numerical value"
fieldId="receipt_receiptId">
| <h:inputText styleClass="editEntity"
| id="receipt_receiptId"
|
validator="#{receiptHome.validateUniqueReceiptId}"
| value="#{receiptHome.instance.receiptId}"
| required="true"
| requiredMessage="Please enter a valid receipt
ID" >
| </h:inputText>
| </q:field>
| <q:field fieldId="receipt_rep">
| <h:selectOneMenu id="receipt_rep"
value="#{receiptHome.instance.rep}">
| <si:selectItems value="#{allUserList.resultList}"
var="user" label="#{user.stringRep}" noSelectionLabel="Select one..."/>
| </h:selectOneMenu>
| </q:field>
| ...
|
my validation method:
public void validateUniqueReceiptId(FacesContext context,
| UIComponent component, Object value) throws ValidatorException {
| if(isManaged() &&
getInstance().getReceiptId().equals(value.toString())){
| return;
| }
| List existing = fetchReceiptList(value);
| if (existing.size() > 0) {
| throwValidationError("Receipt with this ID already exists",
| component);
| }
| }
