ERR: 9999: Error (no description) Unstructured forward jump
Hello!

I have Apache2.2 with mod_perl and Embperl2.3. The following script does not work:

<!DOCTYPE html PUBLIC -//W3C//DTD HTML 4.0 Transitional//EN>
<HTML>
<HEAD>
<TITLE>Test</TITLE>
</HEAD>
<BODY>
[.-
@array = (1,2,3,4,5,6,7,8);
$num = scalar @array;
$i = 0;
-]
<TABLE BORDER=0 CELLPADDING=0 CELLSPACING=10>
[$ while ($i < $num) $]

[$ if (($i % 2) == 0) $]
<TR>
[$ endif $]

<TD> [+ $array[$i] +] </TD>

[.$ if (($i % 2 == 1) || ($num - 1 == $i)) $]
</TR>
[$ endif $]

[- $i++ -]
[$ endwhile $]
</TABLE>
</BODY>
</HTML>

Apache give empty page and in error-log of apache I see the following string:
[746]ERR: 9999: Error (no description) Unstructured forward jump, /usr/local/www/apache22/data/test1.epl Line 14 ->
Line 18

Can anybody help me?

It is complaining because your code would create unbalanced <TR></TR> tags. Why are you writing <TR> when the modulus is 0 but writing </TR> if modulus is 1? I think you should redesign your code.

Actually, it wouldn't generate imbalanced tags - the final if has additional logic to balance the last row - but it does trigger EmbPerl's imbalanced tag detection anyway. Either generate one row per loop iteratiom or turn off EmbPerl's table parsing. Since that loop will probably run faster unrolled once (so there's only one if check in it), and your table should have balanced rows anyway (put the if check on the *contents* of the second <TD>, rather than eliminating the whole element), I strongly recommend the former approach.

I guess it won't complain if you can run the loops and assemble an output table string, inside a [- -] block, and then output the obtained string with [+$table+].
The code will be messier and cgi-like but it can be one alternative, in case you want to keep the processing logic.

George,

To save searching through the docs, here's how to turn off embperl's
form/table/html parsing and just process the various types of code
blocks.

[$ syntax EmbperlBlocks $][# turn off special HTML processing #]

Do funky table stuff here

[$ syntax Embperl $][# back to normal #]

Cheers,

Andrew
