[htmltmpl] Probable bug in TMPL_LOOP

[Boris L. <bor...@gm...>]

Description:

TMPL_VAR used for same variable both in the loop and outside of the
loop, is empty when used within the loop.

Example: a table of account transactions. In PERL we fill the template
with this code:


	my $acct_rec = HTML::Template->new(filename => $args{template});
	$acct_rec->param(ACCOUNTID => $args{accountid});

	my @loop_data = ();
       ...
	$sth->execute(@args{qw/accountid/}) or die "SQL Error:
$DBI::errstr\n"; ## gets transactions from db
		
	while ($row = $sth->fetchrow_hashref) {
		my %tbl_row;  # get a fresh hash for the row data
		$tbl_row{IS_CHARGE} = ($$row{trxtype} eq 'C') ? 1 : 0;
		$tbl_row{TRXID} = $$row{trxid};
		$tbl_row{TRXDATE} = $$row{trxdate};
		$tbl_row{UNAME} = $$row{uname};
		$tbl_row{SNAME} = $$row{sname};
		$tbl_row{QUANTITY} = $$row{quantity};
		$tbl_row{PRICE} = $$row{price};
		$tbl_row{AMOUNT} = $$row{amount};
		push(@loop_data, \%tbl_row);
	}
	$acct_rec->param(TRX_LOOP => \@loop_data);

       <tr style='color: #000000; background-color: #CCFFCC; font-size: 10pt'>
	</TMPL_IF>

<!-- THIS ONE DOESN'T WORK 	-->	
		<td align=left><TMPL_VAR NAME="ACCOUNTID"></td>
<!-- EOC -->
		<td align=left><TMPL_VAR NAME="TRXDATE"></td>
		<td align=left><TMPL_VAR NAME="UNAME"></td>
		<td align=left><TMPL_VAR NAME="SNAME"></td>
		<td align=center><TMPL_VAR NAME="QUANTITY"></td>
		<td align=right><TMPL_VAR NAME="PRICE"></td>
		<td align=right><TMPL_VAR NAME="AMOUNT"></td>
		<td align=left><TMPL_VAR NAME="COMMENT"></td>
		</tr>
</TMPL_LOOP>
	</table>
----------------------------------------------
i.e. ACCOUNTID works outside the loop, inside the loop it stays empty
