Hello,
I designed a search page CustomerSearch and a result page CustomerSearchResult. The
DataObject is doSomeQuery.
In the CustomerSearchResult page there is Date field which has the format of
"dd/mm/yyyy", I did the formatting in
date_onBeforeDisplayEvent(CSpDisplayEvent) using the following sentences:
try {
CSpDatetime datetime = getDisplayFieldValue("theDateField").datetimeValue();
setDisplayFieldValue("thDateField", new
CSpString(datetime.format("dd/mm/yyyy")));
} catch (CSpDatetimeParsingException e) { }
With the above sentences, I got NullPointerException when conducting a search that
does not hit the database. The reason
is since no rows returns the value of datetime will be null, then problem arises when
calling datetime.format(). To fix it, in the
this_onAfterDataObjectExecuteEvent(CSpDataDrivenVisualEvent event) I redirect it to
another page by calling
somePage.load(). But this load will trigger onBeforeDisplayEvent, so still I got the
NullPointerException.
Could anybody give me a solution?
Thanks in advance,
-Fujian
