The %EDITTABLE{}% tag must be directly adjacent to a table for it to work. '<p>' tags are inserted along with newlines at some point in the HTML2TML conversion. These newlines are not always removed. Since newlines have no structural significance in HTML, it is safe (and correct) to remove all newlines at the beginning of conversion, as long as care is taken not to join words previously seperated by a newline.

Use case:

 #!/bin/env perl
use lib "/apps/backed_up/twiki/run/twiki/lib";
use lib "/apps/backed_up/twiki/run/twiki/lib/CPAN/lib";

use TWiki::Plugins::WysiwygPlugin;

$tml = "\%EDITTABLE{}\%\n| 1 | 2 |\n| 3 | 4 |";
print "TML:\n".$tml."\n";

$html = TWiki::Plugins::WysiwygPlugin::TranslateTML2HTML($tml, "", "");
print "\nHTML:\n".$html."\n";

$tml = TWiki::Plugins::WysiwygPlugin::TranslateHTML2TML($html, "", "");
print "\nBACK TO TML:\n".$tml."\n";

print "\n\n\n";
$html = "This is one\nsentence.";
print "\nHTML:\n".$html."\n";

$tml = TWiki::Plugins::WysiwygPlugin::TranslateHTML2TML($html, "", "");
print "\nTML:\n".$tml."\n";

Ah, if only it were that simple. Unfortunately that patch breaks four unit testcases, all related to PRE.

Tthe specific example you gave above works without any code changes. Here's proof (edit this topic and save it):

If you could please point me to the unit tests, I'll run future patches against it and make unit tests for my bugs.

Confirmed this is not an issue with current code, but shows up after changing options from VERY_CLEAN to KEEP_WS, as described in http://develop.twiki.org/~twiki4/cgi-bin/view/Bugs/Item4790.

Buck, I confess I haven't kept the unit tests up to date for all values of options. The unit tests will pass for current values of the options, but I expect you will see a lot of failures if you flip to KEEP_WS.
