Christopher Shubert commented on RF-5512:
-----------------------------------------
This happens for any CSS @ rule. The problem manifests on FireFox 3, but not
on IE 6.
The problem is in the Utils.js file associated with ScrollableDataTable. The
function Utils.getrule() is the cause of the problem. I have included a
reference version of the function (from the 3.3.0 release) below.
On line 7, a reference is made to rules[i].selectorText. This member does not
apply to type 2 rules (@ rules), so any @ rule in any associated CSS will cause
this method to fail. That will result in the placement of headers and frozen
columns failing for ScrollableDataTable.
A proposed fix is to modify line 7 of the getRule function to read:
7 if (rules[i].type == 1 &&
rules[i].selectorText.toLowerCase() == (className.toLowerCase())) {
Thus avoiding references to selectorText for @ rules.
1 Utils.getRule = function (className) {
2 var rule = null;
3 var sheets = document.styleSheets;
4 for (var j = 0; !rule && j < sheets.length; j++) {
5 var rules = sheets[j].cssRules ? sheets[j].cssRules:
sheets[j].rules;
6 for (var i = 0; !rule && i < rules.length; i++) {
7 if (rules[i].selectorText.toLowerCase() ==
(className.toLowerCase())) {
8 rule = rules[i];
9 }
10 }
11 }
return rule;
};

> Key: RF-5512
> URL: https://jira.jboss.org/jira/browse/RF-5512
> Project: RichFaces
> Issue Type: Bug
> Components: ScrollableDataTable
> Affects Versions: 3.2.2
> Environment: windows xp + glassfish v2u2 + jdk 1.6
> Reporter: Rong Tao
> Assignee: Konstantin Mishin
> Fix For: Future
>
>
> This is a very strange bug, when I add a statement '@charset "utf-8"' to a
> css file or the css section of the xhtml file, the Scrollable DataTable
> becomes very strange and cannot be used, the problems are:
> 1. the table header is not displayed.
> 2. scroll bar is not displayed.
> 3. cannot select any rows.
> 4. the 1st and 2nd columns are overlap.
> Very easy to reproduce: download and deploy the demo
> scrollableDataTable.xhtml and DataTableScrollerBean.java; then add '@charset
> "utf-8"' to scrollableDataTable.xhtml, the <style> section of the page should
> be like this:
> <style>
> @charset "utf-8";
> .scrolls{
> width:300px;
> height:200px;
> overflow:auto;
> }
> </style>
> Refresh the page and you will see the problems.
> Not only "utf-8", other charset such as "iso-8859-1" can also cause the issue.
