Subject: Insertion problems with Opera

Hi,

as I couldn't figure out how to post to the Ruby Spinoffs forum 
directly, I am starting a new post here and hope some kind admin can 
move it over to the appropriate forum.

I am trying to insert a new row to a table using prototype's "new 
Insertion.Bottom" which works fine in all popular browsers except for 
Opera. Digging into the code of prototype 1.5.0_rc0 I discovered that 
insertAdjacentHTML() is used for Opera:

---- lines 1147-1154 --->
    if (this.adjacency && this.element.insertAdjacentHTML) {
      try {
        this.element.insertAdjacentHTML(this.adjacency, this.content);
      } catch (e) {
        var tagName = this.element.tagName.toLowerCase();
        if (tagName == 'tbody' || tagName == 'tr') {
          this.insertContent(this.contentFromAnonymousTable());
        } else {
<------------------------

If I insert a simple "throw('bla')" in the first try-block, so that the 
catch-part is run, it works in opera.

I boiled down the lengthy code and put up a test case [1] which uses 
insertAdjacentHTML() to add a new table row and you can see (when the 
updated innerHTML of the table is displayed) how opera seems to 
completely ignore the TR and TD tags yet handling B and I correctly.

---- interesting parts from the test case---->
  tbl = document.getElementById("mytable");
  tbl.insertAdjacentHTML("beforeEnd", 
"<tr><td><b>newCellone</b></td><td><i>newCelltwo</i></td></tr>");
<------------------------

I know I could use DOM functions like insertRow() to circumvent that 
problem but I want to make use of prototype's functions as much as 
possible. I would appreciate any kind of help as to how to maybe change 
the prototype code without breaking other browsers or another way of 
working around this apparent bug.
