Hello,
One more question - I really keep hoping it is the last.
I have a form with a DBRecordloader action - it has a WHERE clause with two fields tested:
Field1 = 'value1' AND Field2 - 'value2'
It works well when records are found, but when no matching record is returned it does not trigger the "On Empty Result" event. In fact it bypasses this and presents a blank form to the user. The problem with this is that if the user adds some data in the empty form and hits Submit, a new record will be created. While I can manage this, it would be better to have the Empty Result triggered so that I can present an error message and a Showstopper (which is what I was trying to do).
What are the criteria for triggering a On Empty Result?
Cheers
Tim

Hi Tim,
Looking at the code I think it should be triggered when the $data array is empty . . . but I suspect there may be a bug and the On Empty Result and On Empty/No Param Passed events are reversed. Here's the code:
Two things to test, one is to add a debugger and check that the $data array actually is empty; two to try the 'other' event and see if that works . . .

//check the result
$request_val = $req_param;//JRequest::getVar($params->get('request_param', ''));
if(!empty($data)){
$this->events['found'] = 1;
}else if(empty($request_val)){
$this->events['nodata'] = 1;
}else if(empty($data)){
$this->events['notfound'] = 1;
}else{
}
