So what do you think is the problem?

Ajax problem in IE7 - get.get() is empty

I am testing Ajax under Mozilla Firefox and IE7. Under Firefox is everything fine but IE7 gives me errors.
My process is the following:
declare
l_counter number;
l_o_name varchar2(2000);
begin
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
htp.prn('<select>');
htp.prn('<option value="x">x</option>');
htp.prn('</select>');
debug.add('ok');
end;
debug_add('ok') adds text 'ok' into debugging table. I can see that this info is being inserted into the table, so the process runs through.
My JavaScript is in ApEx page attributes "HTML header" section and is like the following:
<script type="text/javascript">
function get_AJAX_SELECT_XML(pThis,pSelect){
     var l_Return = null;
     var l_Select = html_GetElement(pSelect);
     var get = new htmldb_Get(null,html_GetElement('pFlowId').value,'APPLICATION_PROCESS=my_proc',0);
     get.add('GTEST',pThis.value);
alert(get.get());
     gReturn = get.get('XML');
     if(gReturn && l_Select){
alert('Never here in IE7');
          var l_Count = gReturn.getElementsByTagName("option").length;
          l_Select.length = 0;
          for(var i=0;i<l_Count;i++){
               var l_Opt_Xml = gReturn.getElementsByTagName("option");
               appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
     get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
     if(document.all){/* why is ie different ask bill */
          pSelect.options.add(l_Opt);
          l_Opt.innerText = pContent;
     }else{
          l_Opt.appendChild(document.createTextNode(pContent));
          pSelect.appendChild(l_Opt);
</script>
alert(get.get()); gives me popup with text "undefined" in IE.
So "if(gReturn && l_Select)" will never become true.
I call it in an item:
onchange="get_AJAX_SELECT_XML(this,'P3201_XXX')"
In Mozilla 2.0.0.7 everything works, i can get correct answer from get.get() and the list is being filled with "x".

Hi,
I'm having a sporatic problem.
Where do you put the encoding?
Content-type: text/xml; charset=UTF-8
Cache-Control: no-cache
Pragma: no-cache
<?xml version="1.0" encoding="UTF-8"?>
I have the following in my ODP function
owa_util.mime_header('text/xml', FALSE );
htp.p('Cache-Control: no-cache');
htp.p('Pragma: no-cache');
owa_util.http_header_close;
then I start my select list:
     htp.prn('<select>');
     htp.prn(ls_default);
and a loop to build the option code

How to solve Ajax problem in Tomcat server

please any one help me

Sorry, I've never done this. I went to the Tomcat site and pulled down the CGI docs, which you might have seen:

No other help available from me. Sorry.

AJAX problems

I have a global select list (self submit) on page #0 in my application. I have a bulk update form on page #2. This bulk update form on page #2 has editable fields and a link also. This link on the bulk update form is programmed to show a AJAX report. This AJAX report is pulled from page #3 onto page #2 using Carl's example. Here are some of the problems that I'm having, any help is really appreciated.
Problem # 1
When I click on the url link in page #2, the AJAX report is pulled properly from page #3, but the pagination on the AJAX report does not work, the error message is "undefined"
Problem #2
When the AJAX report is displayed and I try to change select list (self submit) on page #0 to refresh the bulk update form on page #2, the ajax report generates the following error.
Error      Item ID (1958808806097753) is not an item defined on the current page.
Problem # 3
I'm trying to set "Display as Text" field from the same link in bulk update form. I have set the target to "URL" in the report attributes and called the javascript. It sets the value in session, but does not show the latest value on the screen for the field. The same javascript code works "onChange" for a select field to set the field, but not for a link the report, any ideas are appreciated.
thanks,
Surya

Hello,
Yeah see you had two separate issues.
first issue:
When I try to change the pagination, it gives "undefined error";The problem with this is that the pagination is using page 8 when the report is from page 9. We are going to be enhancing this in 4.0 so this won't be a problem. You have a couple solutions.
1. Disable Pagination and just return all the rows.
2. Rewrite the javascript function that does the pagination so that it points at page 9 , include this in your page. This will break the pagination for any other reports on this page but will enable it for the report that you are pulling from page 9.
function $a_report(pId,pMin,pMax,pFetched,pSort){
   lThis = $u_js_temp_drop();
   var lOld = $x('report_'+pId+'_catch');
   lOld.id = 'report_'+pId+'_catch_old';
       old code
       var l_URL = 'p='+$v('pFlowId')+':'+$v('pFlowStepId')+':'+$v('pInstance')+':FLOW_PPR_OUTPUT_R'+pId+'_';
    var l_URL = 'p='+$v('pFlowId')+':9:'+$v('pInstance')+':FLOW_PPR_OUTPUT_R'+pId+'_';
   if(!!pSort){l_URL += pSort+'::RP&fsp_region_id='+pId;}
   else{l_URL += 'pg_R_'+pId+':NO&pg_max_rows='+pMax+'&pg_min_row='+pMin+'&pg_rows_fetched='+pFetched;}
   var ajax = new htmldb_Get(null,null,null,null,null,'f',l_URL);
   var gReturn = ajax.get();
   lThis.innerHTML = gReturn;
   lOld.innerHTML = $x('report_'+pId+'_catch').innerHTML;
   lOld.id = 'report_'+pId+'_catch';
   lThis.innerHTML = '';
   return;
Second issue:
when change the global select list at the top and the error is "Error Item ID (4571613207429374406) is not an item defined on the current page."This problem was because you were pulling a hidden form item in with your report content from for page 9 "P9_JOB Hidden and Protected", this will always break your page. You should either use an Application Level item or make sure to strip the form item out. I fixed your page by moving the Form Item to a new region and moving that region to region position one. Since that content gets clipped out your fine and it doesn't break.
>
>
Finally when pulling reports from another page you want to make sure that the highlighting options are turned off because it's trying to run javascript that is not in the page and throws errors.
I've made all three of these fixes in your application so you can see them running.

Carl

Apex 4.0 Cascading Select List: ajax problem with german umlaute

Hi everybody,
Apex 4.0
Dad PlsqlNLSLanguage: GERMAN_GERMANY.WE8MSWIN1252
I have problems with german umlaute and ajax cascading select lists (Cascading LOV Parent Item).
The data is populated without a page refresh in the select list when the parent select list changes but special signs like german umlaute are shown as weird characters.
Seems like there is some charset problem with ajax.
This is the only part of the application where special signs like umlaute are messed up. Everything else is fine.
I allready tried to figure out if I can escape the umlaute in the javascript (file apex_widget_4_0.js) but no success here.
Can anybody help me with this issue?
Thanks in advance,
Markus

Hi Markus,
your specified character set in your DAD is wrong. As mentioned in the installation instructions at http://download.oracle.com/docs/cd/E17556_01/doc/install.40/e15513/otn_install.htm#CHDHCBGI , Oracle APEX always requires AL32UTF8.
>
3. Locate the line containing PlsqlNLSLanguage.
The PlsqlNLSLanguage setting determines the language setting of the DAD. The character set portion of the PlsqlNLSLanguage value must be set to AL32UTF8,
regardless of whether or not the database character set is AL32UTF8. For example:Regards

Owa_util.mime_header in select_list_value (or whole ajax) problem

Hi,
I'm using Ajax in "select multiple items". After few problems (I had to turn off session state protection) - I had to organise the same process on the popup.
I open new page of my application in javascript using window.open function. The problem is that when I'm trying to update or insert something on popup I got that kind of message:
"problem with parsing XML file - didn't understand char after document element" - something like that (with additional about my adres and wwv_flow.accept)
source of error page looks similar to that:
<body><desc>this XML genericly sets multiple items</desc><item id="name">test</item></body>Content-type: text/xml; charset=UTF-8
Cache-Control: no-cachePragma: no-cache
<body><desc>this XML genericly sets multiple items</desc><item id="kli">test2</item></body>Content-type: text/xml; charset=UTF-8
Cache-Control: no-cachePragma: no-cache
<select><option value="1">- choose person -</option></select>ERR-1777: Page 2 provided no page to branch to. Please report this error to your application administrator.<br /><br /><a href="f?p=104">Restart Application</a>I use 3 times: - 2 times I put some values into 5-6 textfields and once I'm put some options into select list
OWA_UTIL.mime_header ('text/xml', FALSE);
HTP.p ('Cache-Control: no-cache');
HTP.p ('Pragma: no-cache');
OWA_UTIL.http_header_close;can any one know where is problem? I have the same construction on the static page (not popup) and there everything is ok.
thanks for any help

I have to add, that I understand that error :) it's easy to understand when it's raising - but why there is a problem with owa_util.mime_header - why it adds "content type" line...?
why it was working fine before going to popup...
sorry for English mistakes

XML News / AJAX problem

Hi,
We are using AJAX to call one portal component by sending some parameters to create the link for the news, which we create with xml form builder.
We have modified the .xsl file of xml template and embedd the code to call the portal component.
We are idenfying the news which is created by xml template and creating the link for that news in some other KM folder.
After creating or updating the news with xml template all news will be displayed after compliting the process. But this is happening for first time only. If I try again to create/update the news the news item is creating/updating but browse is stuckup and popup message "Your request is being processed".
Please let me know what might be the problem
Thanks

Ajax + problem with Firefox

Dear All;
I am new to Ajax world. I have following lines of code that works fine on IE and Eclipse internal Browser but when i tried testing on Firefox it did not work.
I have pin pointed the exact location. Please help me out to solve it.
Code:
var xmldoc=req.responseXML.documentElement;
var xrows=xmldoc.getElementsByTagName('entry');
var mytable = document.getElementsByTagName("table")[2];
var mytablebody = mytable.getElementsByTagName("tbody")[0];
for(i=0;i<xrows.length;i++)
alert('inside for loop');
var num=xrows.childNodes[0].firstChild.nodeValue;
alert("num:="+num);/////////////// This line has problem
var site=xrows[i].childNodes[1].firstChild.nodeValue;
alert("site"+site);
In IE (////////////This line has problem) is showing proper output but this is not working with forefox.
Please help me out.
Thanks and Regards;
Vikash Anand.

HI Vikash,
Yes, there a some problems between the browsers that causes every developer pain. A good site to help identifying browsers quirks is http://www.quirksmode.org.
I believe you need an array designation where the xrows element is defined, which looks like your root element. For example:
var xrows=xmldoc.getElementsByTagName('entry')[0];
If this isn't your root element, then you may want to try starting at the root element, then using it's childNodes property, extract the "entry" items.
This is assuming that you are you getting a valid xml document back in your response that has the entry item in it.
The error console of firefox may also help you find the problem. For advanced debugging, firebug is great and is located at https://addons.mozilla.org/firefox/1843/
Hope this helps - Thanks - Mark

Livecycles Process Ajax problem

Hi,
I have a several LCES process that are called from an ajax app. All works well except when the user's session expires/timesout.
After that when the user tries to invoke one of the processes, jboss returns a http 401 error as it's Basic Authentication. I cannot always handel this correctly in ajax as browsers will intercept this 401 error and offer an authentication challenge.
I guess I need something like the remoting end point 'Custom Authentication' but for the REST end point.
1) Could I configure jboss to issue a redirect to a custom html page when a 401 exception accurs?
2) Could I configure jboss to return a 403 or 500 error when there is a 'not Authorized' exception, instead of the 401?
3) If I set "Require callers to authenticate:No" and 'Run as System" for the service is there any way I could then check within my process to see if the current user is actually authenticated?
Any other suggestions?
Thanks in advance,
Michael

1) Could I configure jboss to issue a redirect to a custom html page when a 401 exception accurs?
Ans : Yes you can handle it in front end in ajax by having a seperate exception handler in the server side which redirects the page when 401 exception is thrown from adobe
2) Could I configure jboss to return a 403 or 500 error when there is a 'not Authorized' exception, instead of the 401?
No.
3) If I set "Require callers to authenticate:No" and 'Run as System" for the service is there any way I could then check within my process to see if the current user is actually authenticated?
No you can not since you set "Require callers to authenticate:No" . You can track your session in adobe side only when the user authentication is set to yes

Ajax problem urgently help please?

Hi all,
Can you tell me that is it possible using for when we selected a data from a select list to show the selected item results in a multiselect list.I tried but did not success.For example we select a dept name from a select list and in the multiselect list we will show the empnames for this deptno but more than ona rows.can you tell me how can ı success this?
ı am waiting your helps!

Hi,
You can replace a select list's item by doing something like the following in javascript:
function fillState(country)
     var statelist = document.getElementById("StateList");
     statelist.length=0;
     var opt = new Option;
     var statenames = getStateNames(country);
     var optioncount = 0;
     var isSelected = false;
     for (var n = 0; n < statenames.length; n++)
          opt = new Option;
          opt.value = statenames[n][0];
          opt.text = statenames[n][1];
          statelist.options[optioncount] = opt;
          optioncount++;
Without knowing more about the data you get back, I couldn't tell you how to adjust the above to suit your needs.
In this example, I have an array populated with state codes and names which I then loop through to add into the select list. The "statelist.length=0" line at the beginning clears out any previous data.
Hopefully this should give you an idea of what's needed.
Regards
Andy

Problems after upgrade with dock settings?

Hi all,
I upgraded my 10.4 server to 10.5.2 server today. All appeared to go fine except for 1 stupid thing. On my mac mini clients also running 10.5.2 OSX the dock settings don't work. All I get is the finder icon and the trash icon. However on my iMac I get my normal dock settings? This is all very wierd. I tried re-attaching the minis to the server but still the same problem?
Also when I login to WGM I have to log in as 'root' user? diradmin does not work? Is there a default username that I have forgotten?
Cheers
folks
Chris

Yes, most annoying... it works perfectly on Firefox 2.x. A not so-desirable solution is to go back to Google's Gmail "older interface"... see this control in the top menu after "settings." In this mode, the selection of email addresses when composing is working.
Better still, Apple should fix this brokenness in Safari 3.x, likely an ajax problem!

Javascript block through javascript.enabled false not working as expected in newer versions, any actual way?

Since a few versions, around 24.0 or earlier, when you toggle javascript.enabled from true to false to block javascript, doesn't work after load a page.
Further details:
1.- load a page with javascript enabled
2.- toggle javascript preference to block javascript (javascript.enabled from true to false)
3.- if you interact with javascript elements = they still work
This wasn't this way in earlier versions.
You can check in the following page. You'll see that the only way to actually block javascript execution is to load the page with the preference javascript.enabled set to false (A.K.A. javascript blocked):
http://www.geocities.ws/jothache/event_listener.html
Note: to easy change javascript preferences, for those don't want to play with about:config you can use addons like QuickJava:
https://addons.mozilla.org/en-US/firefox/addon/quickjava/
I find that how it works now, in the latest versions, it is a VERY HUGE SECURITY ISSUE as javascript is never actually blocked when the preference is toggled and AJAX (httpXMLrequest through javascript) still works so the possibilities of lost of privacy inreases, as for example, mouse tracking and send it to the server, not only as the example scripts I posted above.
The question is, is there anyway to really block javascript in the latests versions or should I report this as a bug?
Regards.

Hi guigs2,
if there is no problem in open the bug ticket being a simple user I'll report by myself (if I haven't misunderstood you). (Confirm this and I'll do myself).
About the AJAX problem, here we have a sample test that works after toggle the preference:
http://www.w3schools.com/xml/xml_http.asp
I know about noscript and I don't like it. I prefer to do manually (those measures and more). What bothered me is that even toggle the preference, what in the past did the job of stopping the execution of scripts, now doesn't. In about version 24 it was only happening to event listeners not being blocked (used nowadays for dynamic events assignments). Now is with every javascript code.
About the tracking methods, I'm aware of HTTP tracking without any need of javascript. Even a simple "knock knock" on any kind of server leaves a trace.
I was just pointing that this preference stopping doing its job (stopping scripts executions) has the worst sceneario in a security way with XMLHttpRequest calls.
But one of the things that bothers me too, and it is not related to tracking, is that, in humble machines as mine, some javascript codes make drop whole performance and the preference toggle now does nothing, so the script keeps running without being able of doing anything and sometimes you don't have the option to load a page without javascript because you need some feature of that page that requires javascript what becomes "all or nothing".
Regards.

Zimbra Security Question: Allow / Block embedded javascript or tags?

Technical requirement: Ability to send in plain text and rich text and HTML (limited HTML, no javascripting or harmful tags)
Can javascript or tags be embedded in an email through the Zimbra interface?
Also, Zimbra has developed ALE (AJAX Linking and Embedding), a technology that allows users to embed applets into e-mail. For example, users can share a live spreadsheet in e-mail, rather than sending copies back and forth. Are applets a potential security risk? Can they be blocked?
Thanks for your time.

Hi guigs2,
if there is no problem in open the bug ticket being a simple user I'll report by myself (if I haven't misunderstood you). (Confirm this and I'll do myself).
About the AJAX problem, here we have a sample test that works after toggle the preference:

Firefox 6.0.2 keeps on crashing, problems with ajax calls

Hi,
I am using the jquery form plugin to make ajax calls on my sites, when i invoke the plugin and have Firebug open I get this message:
Could not convert JavaScript argument arg 0 [nsISupports.QueryInterface]
[Break On This Error] callback.data = aElem....getComputedStyle(callback.data, '');
rfhelper32.js
Firebug also tells me that it's limit has been reached 1571 entries shown.
Can someone tell me why this is happening; is there a problem with Firefox that will be fixed. It's not happening in IE9
Here is the information from a recent crash report (which may or not be related to the above problem!)

Try the Firefox SafeMode to see how it works there. <br />
''A troubleshooting mode, which disables most Add-ons.'' <br />
''(If you're not using it, switch to the Default Theme.)''
* You can open the Firefox 4/5/6/7 SafeMode by holding the '''Shft''' key when you use the Firefox desktop or Start menu shortcut.
* Or use the Help menu item, click on '''Restart with Add-ons Disabled...''' while Firefox is running. <br />

''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.''
If it is good in the Firefox SafeMode, your problem is probably caused by an extension, and you need to figure out which one. <br />
