Tested, this is still an issue on current master.

Readding guarantor parameters when error occurs should to the trick. This could be achived same way it is done in bug 24113, but at the end of following code block in memberentry.pl:

if ($nok or !$nodouble){
    $op="add" if ($op eq "insert");
    $op="modify" if ($op eq "save");
    %data=%newdata; 
    $template->param( updtype => ($op eq 'add' ?'I':'M'));	# used to check for $op eq "insert"... but we just changed $op!
    unless ($step){  
        $template->param( step_1 => 1,step_2 => 1,step_3 => 1, step_4 => 1, step_5 => 1, step_6 => 1, step_7 => 1 );
    }  
}

However this really feels like pointless repetition and there should probably be a better way to do this. Or way to make these parameters persist.

Bug 26558: Make guarantor information persist despite an error

When one tries to create an account with patron guarantor and
error occurs (already used username, wrong age etc.), guarantor
information is lost. This patch always saves added patron
guarantor information to the template param new_guarantors.

To test:
1. Create a new account but cause an error that will keep the
account from saving (enter the wrong age for a category or
give the patron a username that's already being used).
2. Search for and select a guarantor.
3. Try to save the account and wait for the "The following
fields are wrong. Please fix them." message.
=> Note that the guarantor information is gone and you need
to search for and select the guarantor again.
4. Apply this patch.
5. Repeat steps 1.-3.
=> Note that guarantor information hasn't been lost.

This patch also removes code block from duplicate patron
check because we now save param new_guarantors even if
error doesn't occur.

To test:
1. Create a new account but cause a duplicate patron error.
2. Search for and select a guarantor.
3. Try to save the account.
=> Guarantor information should persist.

Worked great and will be very helpful.

Can we move that in a condition? We don't need to do it if all went well.

I moved the check in if ($nok) statement. Barbara, would you like to test and sign-off again?
