Item13207: wiki markup not rendered the line before a table

This bug affects both, the FoswikiRenderer as well as the WysiwygPlugin / TinyMCEPlugin. Both need separate patches. The bug is triggered when the lines of a chunk of TML is parsed and lists and tables are extracted and inserted back into the text as HTML. During that course adjacent TML might be affected in a way that the further rendering process does not behave as expected.

You type

| data | data |

| data | data |

| data | data |

| data | data |

You get


Should be


data data


data data


data data

Syntax Syntax

data data

This is caused by the table parser consuming the linefeed before so that when getRenderedVersion is called it is faced with this:

_Syntax_<table class='foswikiTable'><tbody><tr ><td>  data  </td>
<td>  data  </td>

... which then blocks the wiki markup from being expanded.


This fixes it (adding a space before emitting the <table class="foswikiTable>)

diff --git a/core/lib/Foswiki/ b/core/lib/Foswiki/

     if ($headLines) {
         splice( @$lines, $i++,            0, '<thead>' );

However I wonder why the table parser consumes the linefeed in the first place.

The list parser seems to behave the same way though does not show the same error. That is wiki markup the line before a list is rendered just fine. The TML renderer seems to emit enough whitespace infront and after a list so that adjacent TML isn't harmed.

WysiwygPlugin still seems to have problems displaying a proper preview of TML.
