Carl - Show Hide columns and report templates

Question

Carl,
I've implemented the show/hide report column techniques from your demo pages. Thanks for that, it's working well.
I am having a slight issue. I'm using theme12, and when I implement the technique there with the alternating row color template, the functionality works fine. But when I switch to standard report template I have some issues.
Debugging the code :
function html_HideCellColumn(pId){
35 var l_Cell = html_GetElement(pId);
36 var l_Table = html_CascadeUpTill(l_Cell,'TABLE');
37 var l_Rows = l_Table.rows;
38 l_CellI = getCellIndex(l_Cell.parentNode,l_Cell)
39 for (var i=0;i<l_Rows.length;i++){
40 html_HideElement(l_Rows.cells[l_CellI]);
41 }
42 return;
the pId is what expect before line 35, but after, it looks like the html_GetElement is returning null.
Is there something in the template that would cause this change? I am able to reproduce this behavior consistently. Thanks for any input.

Answer 1

Hello,
The table headers in the standard report template of that theme are missing the id attribute so changing this.
&lt;th class="t12header" #ALIGNMENT# >#COLUMN_HEADER#&lt;/th>
to
&lt;th class="t12header" #ALIGNMENT# id="#COLUMN_HEADER_NAME#">#COLUMN_HEADER#&lt;/th>
and your good to go.
Carl
