Hi,
just been using my mobile UI on iOS (& local Mac Safari) in a pilot and got the following error if an invalid value is entered into a field
2012-03-09 12:19 http-8080-6 ERROR com.servoy.j2db.util.Debug Error rendering the page esw_stock_item_usage 9E221F6D-F7B2-4BC1-A219-0D00927BC442 eStockWeb

The field in question (esw_patient) is a global text field that the user is meant to enter a patient number into (either by typing or scanning a bar code)
I have an onDataChange method attached to it (the patient number can be either an NHS no, or a hospital no)
[the relationships are based on the globals.esw_patient to either of the above numbers]
function onDataChangePT ( oldValue, newValue, event )
{
var $pt_name = '';
try
{
if ( databaseManager.hasRecords ( esw_to_patients_nhs_no ) )
{
globals.esw_patient_id = esw_to_patients_nhs_no.id_patient ;
$pt_name = esw_to_patients_nhs_no.forename_1st + ' ' + esw_to_patients_nhs_no.surname ;
}
else if ( databaseManager.hasRecords ( esw_to_patients_rm_pt_no ) )
{
globals.esw_patient_id = esw_to_patients_rm_pt_no.id_patient ;
$pt_name = esw_to_patients_rm_pt_no.forename_1st + ' ' + esw_to_patients_rm_pt_no.surname;
}
else
{
//no match error on pt'
globals.esw_patient = oldValue ;
elements.esw_patient.requestFocus() ;
return false;
}
if ( $pt_name != '' )
{
checkRequired ( );
return true;
}
else
return false;
}
catch(e)
{
globals.esw_error_msg = 'Error ' + e ;
}
}
The error only gets thrown if there isn’t a match on the patient and doesn’t always happen (i.e. sometimes my code correctly highlights same box in red putting original value back in), but it has happened on iOS & Mac (both using webkit browsers)
Under normal (i.e. not test/pilot) usage, the patient number should always be found if scanning, but if user is entering by hand and enters an incorrect value, there might not be a match.
Please can anyone advise me what is going wrong, as when system goes live (hopefully in a couple of weeks ), we can’t have the solution crashing out…
[One more thing, the overall system is running in the Servoy Framework by Sanneke, which handles the login to solution, but as soon as they go into it, I check if they are running web client and if so switch them to my mobile UI in a module ‘eStockWeb’ which is why things are prefixed by esw)
Thanks
