Hi,
I have a static{} block I want to execute on our project base page to load data
from our database to a set of hashtables. These I'll then store in global session.
Unfortunately I get a null pointer when the project loads the first time. It looks
like the dataobject isn't known to the project at that point.
Should I add the code to the this_onAfterInitEvent of the dataobject?
Any ideas for getting around this?
Regards
Damian
Code:
static
{
// Method to retrieve or store field display values
loadHashTables();
}
/**
* Searches in the DataObject <i>doqFieldDisplay</i> (table field_display)
* for the entries for the given project. The resultset is used to create
* the necessary lookup tables for controlling field display on the individual
* pages.
*
* @return A number of Hashtables that contain as
* key the <i>field name</i>, <i>page name</i> and
* <i>cntry code</> concatentated as the key.
*/
protected static final synchronized void loadHashTables ()
{
CSpLog.send("pgBase", CSpLog.ERROR, "loadHashTables()");
boolean locked = true;
String field_name = new String();
String page_name = new String();
String cntry_code = new String();
try
{
// Check to see if we can access the global session
// Attempt to lock the session while we read from it.
while (! (locked = CSpider.lockGlobalSession ()))
{
java.lang.Thread.sleep (new Long("250").longValue());
}
CSpValue sessionExists = CSpider.getGlobalSessionObject
(Constants.getFieldDisplaySession());
// Verify if we need to create the session objects
if (sessionExists == null)
{
CSpSelect doqFldDsp = (CSpSelect)CSpider.getDataObject(
"doqFieldDisplay" );
