Setting cache level leads to JavaScript error

Hi there
We have a number of BW reports that are published through our Enterprise Portal.
The reports run fine by themselves.
They have been published to the portal and assigned to roles, and run fine.
Now we are looking to enhance performance, so have started playing around with cache settings.
All of a sudden, there is a JavaScript error on the template.
If the cache level is set to anything other than NONE, I get an error.
Closer investigation of the resulting code shows that the statement for including javascript files changes if caching is used. The 2 statements are shown below:
Working - <script language="JavaScript" src="/sap/bw/Mime/Customer/JavaScript/ToolbarJS.js"></script>
Not working - <SCRIPT language="JavaScript" src="http://portalprod.xxx.co.za:50000/irj/servlet/prt/portal/prtroot/com.sap.portal.contentfetching.bwtunnel?key=ge4unk2eh9gnueyz3vkiuw==&target=http://bwprod.xxx.co.za:8100/sap/bw/mime/customer/javascript/webtemplate.js">
</SCRIPT>
Has anyone seen anything like this before?
The error that comes up is a JavaScript error saying Object expected .... basically I don't think it can see the included javascript files.
Any ideas would be greatly appreciated at this point.
Cheers,
Andrew

Hi,
Try doing a trace on the network traffic in order to find out if the javascript for the url http://portalprod.xxx.co.za:50000/irj/servlet/prt/portal/prtroot/com.sap.portal.contentfetching.bwtunnel?key=ge4unk2eh9gnueyz3vkiuw%3d%3d&target=http%3a%2f%2fbwprod.xxx.co.za%3a8100%2fsap%2fbw%2fmime%2fcustomer%2fjavascript%2fwebtemplate.js">
has been downloaded, and if not, what is the error code. It might be a authorization problem.
You could fex use ethereal (from http://ethereal.com) to do the sniffing. (use options tcp port 50000, otherwise you would be overwhelmed with data)

How can I get Firefox to display details about a JavaScript error when one occurs?

When in Internet Explorer I can set it up to display JavaScript errors as follows. Select Tools then Internet Options… then the Advanced tab. Under Browsing, find '''Display a notification about every script error '''and be sure its box is checked.
I cannot find out how to do this in Firefox. I would like for it to display details about JavaScript errors when they occur instead of doing nothing.

Setting EP cache level breaks BW reports

Does that mean that my JavaScript files need to be loaded onto the Portal server instead of the BW server, and then referenced from there?
Seems a bit odd to me, but I guess if that is what it takes, then I will have to make a plan.

Setting the property "Cache Level" of the pcd object to "None".

Hi all
I have an EP 6.0 on NW04 SPS 17. I need to solve a problem and found note 960975. My question is, how could we change the setting the property "Cache Level" of the pcd object to "None"? Where should I go? Is it on the NWA, Visual Admin, Configtool or somewhere else?
Many thanks before.
Regards
Agoes

Hi Agoes,
By using the tool Support Desk -> Portal Content Directory -> PCD Administration you can do this. Please note that this tool should only be used in debugging situations.
There is a new section "Release a Unit from the cache cluster wide" in this tool. With this new functionality, you can remove an object from the cache on all nodes in the cluster. If the object is still in use, it will be reread immediately from the database
Releasing the entire PCD cache can severely affect performance. Hence, if there are inconsistencies suspected with a single object, e.g. a role or an iview, the new section "Release a Unit from the cache cluster wide" can be used to evict the given object from the cache on all nodes in the cluster.

JavaScript error using UIXML to generate frames

Hello all,
I am trying to use the uix:frameBoderLayout and uix:frame elements to generate an HTML page with frames. I get a Javascript error when running the testFrame.uix in JDeveloper 9.0.3. Both MSIE and Netscape yield the same error.
The JavaScript error is:
JavaScript Error:
http://20.19.205.86:8988/pssWeb-pss-context-root/testFrame.uix,
line 1:
_checkLoad is not defined.
The HTML generated is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html dir="ltr" lang="en-US">
<head>
<title>Property Security System Application</title>
<link rel="stylesheet" charset="UTF-8" type="text/css" href="/pssWeb-pss-context-root/cabo/styles/cache/blaf-en-netscape.css">
</head>
<body class="xc" style="background-color:#FFFFE1" onload="_checkLoad(event)" onunload="_checkUnload(event)">
<script src="/pssWeb-pss-context-root/cabo/jsLibs/MarlinCore.js">
</script>
<frameset border="0" rows="100%,*">
<frameset rows="*,0" onresize="if(!frames['_uixJS'].cached){location.reload();}">
<frameset rows="null,*,null">

</frameset>
<noframes>
</noframes>
</frameset>
</body>
</html>

_checkLoad is contained in the MarlinCore.js file. That file should be in cabo/jslib/ directory.
Two things strike me odd about the generated HTML code with relation to JavaScript. First, I expect to see JavaScript source files declared in the head portion. Second, the source files is declared after the onload call is made to the _checkLoad function.
The third thing that I can see possibly causing the error is that the MarlinCore.js file is not visible to the server and therefore not delivered to the browser. But I am not certain where to find the files used by the embedded OC4J server.
Is this a bug in 9.0.3?
The uix files follow. All three framed pages (topFrame.uix, centerFrame.uix and bottomFrame.uix) display nicely in the uix preview and run nicely in the embedded OC4J.

Your assistance is appreciated,

Did you create the files with JDev 903 preview or JDEV 902? If you created with JDEV 902 and upgraded your project to
903 you need to delete all the files in the cabo directory in your public_html directory. That should get rid of your
javascript errors.

Interactive report javascript error: missing ) in parenthetical

Running on 11g, APEX 3.1.2.00.02:
I have several interactive reports that appear to the user to hang up when they try to sort by clicking a column header (the spinny circles never go away and the page doesn't do anything). Upon the column header click, Firebug reports a javascript error: "missing ) in parenthetical", which I now believe is related to this string:
<SCRIPT SRC="/oracle_smp_chronos/oracle_smp_chronos.js"></SCRIPT>
being appended to the results of an AJAX call the report makes to get refreshed data.
I believe the expected result data (JSON format?) is no longer valid with that string at the end.
We had to prevent that from happening when running our own onDemand service, but I don't know how to stop it in this case.
Has anyone seen, or solved, this one before? Can anyone tell me how to turn off that smp_chronos stuff to see if I'm right? It's for performance monitoring or some such, isn't it?
TIA,
AFC

Our DBA tells me: there is a setting in the web cache called End-User Performance monitoring. it need to be disabled ( "Site-Specific End-User Performance Monitoring Rules")
This took care of the problem.
Thanks for listening.

Javascript error when a table is placed within a table popin.

Hi experts,
I have a node 'Parent' which contains one attribute and a non singleton child node called 'Child' which contains five attributes.
I have created a Table 'OuterTable' in the view. The 'datasource' property of this table is set to the node 'Parent'. I inserted a popin in to this table and added another table 'InnerTable' as the content of this popin. InnerTable is bound to the node 'Child'.
For each parent element, there will be 'n' number of child elements. When i run the application i can see 'm' number of table popins(corresponding to 'm' number of parent elements) and inside each popin a table containing 'n' rows(corresponding to 'n' number of child nodes for each parent element).
When i try to select a row from the table in second or third popin, the browser shows a javascript error at the bottom left hand corner. Although it does not affect the application, i am curious why this is happening.
The main problem is that, we have to call this webdynpro application from a function module in R/3 which will show the application in the IE engine inside SAP GUI. In this case when we select any rows in the table, a pop up with a message 'Internet Explorer Script Error' comes and we are not able to proceed with the application.
Any help to resolve this issue will be highly appreciated and rewarded with points
Shabeer.

Hi Shabeer,
Can you try this
File location
1) <Installation Drive>\usr\sap\<System Name>\
<Instance Name>\JC00\j2ee\cluster\server<Number>\
apps\sap.com\irj\servlet_jsp\irj\root\portalapps\
com.sap.portal.htmlb\jslib\jslib/sapUrMapi_ie6.js
2) j2ee_<Instance Number>\cluster\server\services\
servlet_jsp\work\jspTemp\irj\root\portalapps\
com.sap.portal.htmlb\jslib\sapUrMapi_ie6.js
and try this
Find the function "function sapUrMapi_init()"
and the line
ur_system.emptyhoverurl = ur_system.mimepath+"emptyhover.html";
Add the following if condition before this line:
if (ur_system.emptyhoverurl == null || ur_system.emptyhoverurl == "")
so that the result reads like follows:
if (ur_system.emptyhoverurl == null || ur_system.emptyhoverurl == "")
ur_system.emptyhoverurl = ur_system.mimepath+"emptyhover.html";
Take a backup . You can try this on your local system before trying on the server.
Keep in mind that the object can be cached in both the server and
browser cache.

Dreamweaver and Javascript error only on one site

I receive the following error when trying to select recently modified files from the files panel.
While executing onClick in SelectRecentlyModified.html, the following JavaScript error(s) occurred:
At line 370 of file "C:\Program Files (x86)\Adobe\Adobe Dreamweaver CS5\Configuration\Menus\MM\SelectRecentlyModified.js": DWfile.getAttributes(listItem) has no properties
I have 4 sites built in DW and only one site is giving this error. After many days of searching the web and trying the few steps I can find on the web related to this error I still have not resolved it.
I am using CS5 Suite, Win XP, have IE7 and Firefox but my default brower is Firefox.

I've now tried that command on multiple sites, including brand new ones I created solely for testing purposes. I also tested it on the same site files on my testing server and in my Subversion repository. I got the same error message every time. This leads me to believe the problem is with the script itself. I would really like to be able to use this feeature.
In addition, the Dreamweaver Help for this feature (copied below) suggests I should be seeing options in this feature's dialog box that I'm not seeing:
Find recently modified files in your site
In the collapsed Files panel (Window > Files), click the Options menu in the upper-right corner of the Files panel, and then select Edit > Select Recently Modified.
Do one of the following to indicate search dates for the report:
To report on all files modified in the last several days, select Files Created or Modified in the Last and enter a number in the box.
To report on all files modified within a specific time frame, click the Files Created or Modified in the Between radio button, then specify a date range.
(Optional) Enter a user name in the Modified By box to limit your search to files modified by a specific user between the dates you indicated.Note: This option is only available for reports on Contribute sites.
Select a radio button to indicate where you want to view files listed in the report, if necessary:
Local Machine
if the site contains static pages.
Testing Server
if the site contains dynamic pages.Note: This option assumes you defined a Testing Server in the Site Definition dialog box (XREF). If you have not defined a Testing Server and entered a URL prefix for that server, or if you are running the report for more than one site, this option is not available.
Other Location
if you want to enter a path in the text box.
Click OK to save your settings.Dreamweaver highlights the files that were modified within the selected time frame in the Files panel.
I have set up a testing server for the site (I'm running Apache on my local Mac), and it works. Yet I do not see any option in the dialog box to indicate that I can view the files in a different location. But it's a moot point since I can't view them in any location due to the javascript error.
Adobe, please advise.

CS6: Edit - Keyboard Shortcuts javascript error

Does anyone know how to fix this:
In CS6, when I right-click a new snippet and select Edit Keyboard Shortcuts, I just get a javascript error, the same error I get if I try to create a keyboard shortcut directly from the menu at the top of the screen, Edit -> Keyboard Shortcuts.
The error is "At line 321 of <path>\Keyboard Shortcuts.js getMenuTree: Argument number 1 is invalid."
After that, where the list of standard shortcuts should appear, the list is blank. All the other built-in shortcuts also are blank, and trying to duplicate the standard set just creates a blank set and doesn't let me add anything. Deleting Dreamweaver's cache file, the blahblah.dat thing, doesn't fix it.

Javascript Error! Error number: 45 error string: Objects is invalid line: 387, Line 428

I am running Indesign CS3 on an XP computer. I installed a plugin for barcodes from teacup Software, Barcodemaker for Indesign CS3 win and this has crashed my Indesign CS3.
Everytime I startup I get this Javascript error! Error number: 45 Error string: objects is invalid line: 387 I hit enter and iget the same message line: 428.
The adobe knowledge base has a message http://kb.adobe.com/selfservice/viewContent.do?externalId=kb402389&sliceId=2
I can't find the file Pluginconfig.txt on my computer to delte as suggested in this article. Can anyone help with this issue.
I have uninstalled the plugin and I have try to repair/reinstall my copy of Indesigh CS3 version 5.0.4 but it still is not possible to use Indesign.
Has anyone encoutered this problem? Can you tell me where to find this file Pluginconfig.txt.

C:\Documents and Settings\[username]\Local Settings\Application Data\Adobe\InDesign\Version 5.0\Caches\InDesign Recovery
This is a hidden folder, so you'll need to set Explorer to show hidden files if you haven't already. Start by just renaming the folder to _InDesign Recovery and it should rebuild on the next launch if this is going to work. If it doesn't work, you won't have lost anything.
Might work even better if you were to try a system restore, however. Do you have a restore point from before the plugin was installed?

Konductor javascript errors in DW CS4

I have just installed the konductor extension (for allowing content management by my clients) and I can't get it to work. All I get is javascript errors. And the konductor properties panel isn't functioning - none of the editing options I can choose from show up there. I set up a test site following the (limited) instructions that are available, put a couple of editable divs on a page, and tried to define the settings for them. Here are some of the error messages I am getting:
I am a designer; I know very little about code. Can anyone help me get the extension to work properly?

Hey Kalynn, it doesn't seem like you are doing anything wrong, you are following all the correct steps.
I tried following the same steps on Mac OS 10.6.3, Konductor Extension 1.1.1, but could not replicate the error. These are steps I followed, let me know if I did something differently to yourself:
Select the Sites > New Konductor Site > Empty Site... menu item and enter relevant details
Select the File > New... menu item, select Blank Template, select HTML Template, select <none>, then click Create
Switch to Split View, then create 2 div elements (I just did this quickly in the code)
Select each div element in the design section, select the Insert > Template Objects > Editable Region menu item and enter relevant name
Select the editable region in the design portion. At this point, the Konductor Property Inspector shouldn't show up (Due to the split view thing)
Switch to Design View. This step used to cause an error, but this was resolved a while back. I want to make sure it hasn't cropped up again...
Deslect the editable region, then reselect it. For me, the Konductor Property Inspector now displays.
After this, I rotated though a few different views and selection states, but could not trigger an error. I may have done something differently though, or there may be something different in my environment.
I know this sounds like the classic "have you rebooted your computer" question, but have you tried uninstalling the extension through Extension Manager, and then reinstalling the extension? Also, was the extension installed before Dreamweaver was run for the first time?
Let me know if I did anything differently and just quick yes / no answers to the above questions if you like. If these don't lead to a solution, I'll send you a special build the will help us fix the problem.
Thanks again helping us out with this!

Javascript error calling a bi 7.0 webapplication from a bsp application

Hi everyone,
This is the scenario we're facing a javascript error :
Enterprise Portal is calling a custom bsp application ( via an iview in the enterprise portal ) in the bi system with a parameter "template_id" and a value, which is the technical name of a bi web application.
The bsp application is evaluating the parameter by some custom code and creating a html page with a redirect or a maintenance message to the bi web application passed with the parameter "template_id".
The html link to the bi web application is created according to this documentation :
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/46/03d4ac801467e6e10000000a1553f6/content.htm
Purpose of the bsp application :
in the bi system there is a database table to maintain a flag for each webtemplate and infocube, which should not be called via the enterprise portal for a certain time ( some kind of maintenance switch ). The bsp application then decides to show a maintenance page for the called webtemplate or to send the redirect page to the client.
The process described above is :
working with the bi 7.01 sp7 in the bi ( enterprise portal sp22 ) in the productive system.
working in the Q&A system bi 7.01 sp8 with bi 3.5 web applications.
not working in the Q&A system bi 7.01 sp8 with bi 7.0 web applications.
The javascript error calling bi 7.0 web applications is :

We've opened a message. Support center is saying that this method isn't supported by sap. We should ommit the bsp application and the used functionality.

Hello everyone,
we did some further analysis on this problem und we think we found the problem.
The error occurs while trying to execute the standard url for web templates inside a Enterprise Portal Frame, for example
https://XXX:XXX/irj/servlet/prt/portal/prtroot/pcd!3aportal_content!2fcom.sap.pct!2fplatform_add_ons!2fcom.sap.ip.bi!2fiViews!2fcom.sap.ip.bi.bex?TEMPLATE=XXX
While executing the URL a HTML-Page with some embeded Javascript-code is sent back to the browser.
In this Javascrip-Code, the method-call "dsmObj.registerAll" leads to a script error in Internet Explorer.
dsmObj.registerAll("pcd:portal_content/com.sap.pct/platform_add_ons/com.sap.ip.bi/iViews/com.sap.ip.bi.bex", "GUSID:6FC9SuhGDPIMMLwOdeHEIg--_7WQud13yeLJDz2kYoQFSg--", "1307605928212");
In SP7, the method "dsmObj.registerFullKey" is called instead of "dsmObj.registerAll". This has changed in SP8.
dsmObj.registerFullKey("GUSID:iBPvyska9*xE_JBalkQG2g--YyKv2C3NToP0I79Mw7EO8w--", "1307606479963");
The object "dsmObj" seems to reference the parent frame of the Enterprise Portal.
Has anyone seen this before? Any ideas how we can fix this?
Kind regards,
Matthias

Page leads to proxy error sometimes or taking too much time to load

Hi All,

Web server: Apache 1.3.9 (Oracle 9iAS 10.0.1.2.2)
I am getting the below error at first time when I try to open a page or the page takes 3 to 5 mins to load. From second time on wards, It takes 5 to 8 sec to open as normal. I debugged the page and checked the log. Logs and execution time are looking normal. why the page takes too much time to load at first time or it leads to proxy error?? Is anybody got same experience before??
Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET/pls/apex/f.

Please guide me to find out and resolve this issue....
Thanks in Advance

Hi this is what the solution given by your link
A.1.6 Connection Timeouts Through a Stateful Firewall Affect System Performance
Problem
To improve performance the mod_oc4j component in each Oracle HTTP Server process maintains open TCP connections to the AJP port within each OC4J instance it sends requests to.
In situations where a firewall exists between OHS and OC4J, packages sent via AJP are rejected if the connections can be idle for periods in excess of the inactivity timeout of stateful firewalls.
However, the AJP socket is not closed; as long as the socket remains open, the worker thread is tied to it and is never returned to the thread pool. OC4J will continue to create more threads, and will eventually exhaust system resources.
Solution
The OHS TCP connection must be kept "alive" to avoid firewall timeout issues. This can be accomplished using a combination of OC4J configuration parameters and Apache runtime properties.
Set the following parameters in the httpd.conf or mod_oc4j.conf configuration files. Note that the value of Oc4jConnTimeout sets the length of inactivity, in seconds, before the session is considered inactive.
Oc4jUserKeepalive on
Oc4jConnTimeout 12000 (or a similar value)
Also set the following AJP property at OC4J startup to enable OC4J to close AJP sockets in the event that a connection between OHS and OC4J is dropped due to a firewall timeout:
ajp.keepalive=true
For example:
java -Dajp.keepalive=true -jar oc4j.jar
Please tell me where or which file i should put the option
java -Dajp.keepalive=true -jar oc4j.jar ??????/

JavaScript error on Interactive Report

When clicking on the Magnifying glass of my interactive report search bar, I receive a JavaScript error.
Line: 2 Char: 15193 Error: Syntax Error
The page that I am navigating to has 2 regions. The first is an interactive report and the second is an html region that has an Iframe reference to another interactive report. Based upon the selection of a radio group, the corresponding region(interactive report) displays. All other interactive reports work fine when their pages don't have a region with a Iframe reference.
If I navigate to another page after the error occurs and then come back to the page, everything then works fine. The error only happens on the first use. I have installed the latest patch set for Apex 3.2 I currently am running 3.2.1.00.11. I read a bug on Metalink that referenced this javascript error, but applying the patch set does not seem to fix the issue. The bug was 8568894.
Any help would be appreciated.

This might be useful for others also...
After hours and hours of debugging headers and responses and comparing pages to others which work, I realised that this interactive report's display condition is based on REQUEST = SUBMIT.
As such, the actions menu will NOT set the Request parameter when clicking in the actions menu and the Apex engine refuses to send anything back to the browser - not even an error message.
I'll raise a bug for this via Oracle Support.
Cheers, Pete
