I have a visualForce page that contains an object which has a autonumber as name. When the user presses save, the object is stored and I want the name to be populated with the name of the object. I'm guessing that the autonumber is generated when the object is inserted into the DB but if I try to ApexPages.addMessage the name after it has been added to the DB, it says that I cant reference a null object, implying that the name is not set after it has been inserted.
Here is my code (in a nutshell):
public void addEditProjectElement( )
{
elementsExist = true;
try
{
project_element = currentProject.Project_Element__r;
ApexPages.Message msg;
if ( project_elements_map.keySet( ).contains( currentProject.project_element__r.id ) )
{
update project_element;
msg = new Apexpages.Message( ApexPages.severity.INFO, project_element.Name + ' is updated.' );
}
else
{
insert project_element;
msg = new Apexpages.Message( ApexPages.severity.INFO, project_element.Name + ' is added.' );
}
Apexpages.addmessage( msg );
project_elements_map.put( project_element.Id, new ProjectElementDTO( project_element, project_elements_map.size( ) ) );
} catch( Exception exc )
{
ApexPages.addMessages( exc );
}
}
and here is my VisualFore page:
<apex:outputPanel id="ProjectElementOutputPanel">
<apex:pageblockSection id="ProjectElementInputError" collapsible="false" title="Bouw Elementen" columns="1">
<apex:messages styleClass="error, info"/>
