BEA 8.1 SP3 / Java Portlets replaceDynamicMarkup() Javascript error

Question

Hi
I have been using BEA Portal SP2 for a while and have swapped over to SP3 but I am now seeing a Javascript error in the BEA portal page within a javascript method replaceDynamicMarkup(). This occurs when I have multiple Java Portlets on a page (can be the same portlet multiple times) and you maximise the portlet either programmatically or via the maximise button.
The problem appears to be that when you maximise the portlet, the contents of the replaceDynamicMarkup do not change and try to access html associated with portlets not being displayed on the page. For example, the method with one portlet maximized and with 2+ portlets in normal mode is the same.
With one portlet maximised, so only one visible:
function replaceDynamicMarkup()
{  var elem = document.getElementById("0_32");
elem.innerHTML = "<span id='0_32'>SP3Test</span>";
var elem = document.getElementById("0_38");
elem.innerHTML = "<span id='0_38'>SP3Test</span>";
because the other portlet isnt present both netscape 7 and IE 6 throw a "null" Javascript errors. As there is no check to ensure that the element is actually retrieved from the dom. Is there a workaround / fix for this?
Thanks
Andrew.

Answer 1

Hi,
I am not sure whether i am identifying the problem correctly or not, but we have seen this behavior with the portlets, as when we have two instances of a portlet on the same page and both are using same JavaScript function ,since all the portles are included in the same page we need to use Encode namespace for the java script functions so that a portlet Instance can identify its Java script function correctly
While writing javascript function use
function <portlet:nameSpace/>doSubmit()
alert("good Morning ");
While calling Javascript function use
<input type=button value="Sumbit" onClick="javascript:<portlet:nameSpace/>doSubmit()"/>
See if this can solve your Java Script problem.
