good morning all,
 
 I am still struggling with the error of debug-time the app crashes without I get a hint where the problem is. in the line :
 
ids_groups.dataobject = 'd_pfcsecurity_applookup'
 
the app crashes without any error message.
 
the whole script (belongs to the function of_initsecurity(...), the object which contain it is: pfc_n_cst_security from library: mey_ext_gefis.pbl )is the following:  
//////////////////////////////////////////////////////////////////////////////
//
// Function:  of_InitSecurity
//
// Access:  public
//
// Arguments : 
// atr_trans used to connect to the database
// as_appname application id
// as_userid user id


// as_defaultgroup group to be used if the user does not belong to one
// ab_precache preload all settings for the user - Default is false
//
// Returns:  Integer. 1 = OK
// -1 = Transaction not connected
// -2 = Application not in dataabse
// -3 = User not in database
// -4 = User is not a member of any groups and default group does not exist
// -5 = Default group not supplied
// -6 = Error retrieving information
//
//
// Description: Initialize the database connection, application and user id's. 
// Used when setting security.
//
//////////////////////////////////////////////////////////////////////////////
//

end if

// set the values
ib_initsecurity = true

is_userID = as_userid
ib_precache = ab_precache
itr_trans = atr_trans


If ab_precache Then
// go and retrieve ALL settings for this user
ids_items.dataobject = 'd_pfcsecurity_allcontrollist'
ids_items.of_settransobject(atr_trans)
li_rc = ids_items.retrieve(as_appname, as_userid)
// read in the setting for all the groups the the user belongs to
For li_idx = 1 To ii_numgroups 
li_rc = ids_items.Retrieve(is_app, ids_groups.object.group_name[li_idx] )
If li_rc = -1 Then
Return -1
Else 
// Resort to force ordering
ids_items.sort() 
il_numberofrows += li_rc
End If
Next
End If


Return 1
 
 
Why is crashing my app in line : ids_groups.dataobject = 'd_pfcsecurity_applookup' ?
 
Thanks in advance.
