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);
}
}
