When developing a webapp with Richfaces, you will sometimes encounter a javascript “runtime error”. This error will only occur in MS Internet Explorer (seen at version 6/7).
I struggled and but then i found the reason and the solution. In Richfaces 3.3.2 CR1 there is some JS code in form.js, which tries to get all elements from the surrounding form. Like this
//..
var field = form.elements[fields[i]]
//..
This seems to fail only in Internet Explorer.
But why? I don’t know for sure, but it only occurs when you nest forms. Nesting of forms is invalid HTML, so it is not a bug in Richfaces. Check your UI structure instead.
<!--Not valid / never do this-->
<h:form>
<h:form>
<!--stuff-->
</h:form>
</h:form>
Remember: NEVER ever nest forms into form.
See Primefaces forum.
When there is enough time, i will provide a more detailed example.
A plain and simple solution to remember the sortOrder of a rich:dataTable can be found
in the Richfaces forum.
I wanted to present a button with an onclick-handler which invokes the browser printing dialog.
With simple code like this
<button onclick="window.print();return false;">Print me</button>
It works in Mozilla Firefox 3.x and MS Internet Explorer 6, when the page is called directly. You can click the button, the dialog appears and everything is fine.
Issue 1: But when the page is the result of a JSF-navigation-rule-based <redirect/> the IE6 behaves in a strange way: You click on the button and nothing happens – no js-code is invoked. It works after a manual reload using the F5-key.
Issue 2: I figured out, that not even the following code works in IE6. After such a redirect.
<script type="text/javascript">
jQuery(document).ready(function(){
//your js-code here
});
</script>
Does anybody can reproduce the issues? And knows solutions for them?
Workaround for Issue 1:
Use self.print() instead of window.print(). This works in my usecase in FF3.x and IE6.
<button onclick="self.print();return false;">Print me</button>
