Problem with javascript and jstl

Hi,
Can we access javascript variable in a jstl tag..
For example
function clickGroupByPO()
var brand="hello";
<c:set var="Var" value="${brand}" />
alert("${Var}");
I am geeting balnk in the alert.. I want to assign brand to value attribute in <c:set>
Thanks and Reagrds,
radha

No, you cannot do it this way because java script is executed on client side.

Problem with Javascript and opening a new page

Hi,
I'm developping a website with Java Server Faces.
I've a problem with JavaScript.
I have a table, and each row of that table, has a button, to display more information about that specific row. I want to display this information in a new window. For this I want to use JavaScript.
The new window, of course, needs some information of the other window, to show the right data.
The first time I click the 'more-information-button', it works perfectly, but from than on, he keeps showing the same information...
Here is my jsp-page of the first page (the one with the table):

My interactive form is a hot mess (multiple problems with javascript and formcalc)

I have been working on a dynamic expense report form for our company but have run into a number of problems. I would appreciate help with any of these!
Problem 1:
Last subform: Table 4 (Miscellaneous Expenses) - This subform does not force down the footer section (signature, comments) like the other subforms do. The table is located in a positioned subform inside a flowed subform. The other 3 tables have no problem pushing the data down.
Problem2:
The minus button on the tables (to subtract a row) USED to work but now do not.The minus button on EVERY table is broken.
Problem 3:
The add row button still works fine on most of the tables (with exception of the last table, MISC Expenses). If I add a few lines to the last subform it seems the buttons stops working altogether past row 3. you have to add 2 rows to the final table (Misc Expenses) to see what I mean. It seems to me that this problem is probably related to Problem 1 somehow.
Problem 4:
Can't get GRAND TOTAL working no matter what I try.
I uploaded my work in progress here: www.essential-equipment.com/pdf/ExpenseReport.pdf
If anyone is able to help me I would greatly appreciate it. Also, would it be hard to make this form able to carry over to a new page?
Thanks in advance to anyone that helps

Hi.
Problem 1:
The sourrounding subform "Table4Subform" is not set to fit the hight automatically.
Problem 2.
The remove script is way to complex, use this script instead:
if (this.parent.parent.instanceManager.count > 1) {
this.parent.parent.instanceManager.removeInstance(this.parent.parent.index);
Problem 3:
Remove the Grouping "Body", then the subform flow crrectly to the next page.
Problem 4:
The reference to the total fields are not correct, that's why the grand total script fails.
Change it into:
Sum(Table1Subform.Table1.FooterRow.Total1, Table23Subform.Table2.FooterRow.Total2, Table23Subform.Table3.FooterRow.Total3, Table4.FooterRow.Total4)

JSF problems with Javascript

Hi everyone!!
The situation is this: I have a datable with one of its columns make an h:commanLink, which has two f:params, its actionListener is a function of a ManagedBean. This is JSF, not MyFaces. In IE, When the link is pressed, it shows a javascript error: " 'elements.idVar' is null or it's not an object ", however in Firefox, it works perfectly. I have been looking for the problem and it have to do with this:
</form><a href="# onclick="clearFormHiddenParams_formResultado('formResultado');document.forms['formResultado'['formResultado:_idcl'].value='formResultado:dtTablaResultados:0:_id10';document.forms['formResultado']['idVar'].value='37';document.forms['formResultado']['idMun'].value='168'; document.forms['formResultado'].submit(); return false;"><span id="formResultado:dtTablaResultados:0:itColumna3" title="AREA COSECHADA EN CULTIVOS PERMANENTES">1,230</span></a></td>
</tr>
<tr class="standardTable_Row2">
<td><span id="formResultado:dtTablaResultados:1:itColumna1" style="text-align:center;" title="Código Municipio">718</span></td>
<td><a href="javascript:void(0)" onclick="javascript:window.opener.opener.showLink('SASAIMA')"><span id="formResultado:dtTablaResultados:1:itColumna2_l" title="Municipio">SASAIMA</span></a></td>
<td><form id="formResultado:dtTablaResultados:1:_id9" method="post" action="/ConsultaEstadisticasGeo/resultadoConsulta.jsf" enctype="application/x-www-form-urlencoded">
<input type="hidden" name="com.sun.faces.VIEW" id="com.sun.faces.VIEW" value="_id39:_id41" /><input type="hidden" name="formResultado:dtTablaResultados:1:_id9" value="formResultado:dtTablaResultados:1:_id9" /><input type="hidden" name="idVar" /><input type="hidden" name="idMun" /><input type="hidden" name="formResultado:_idcl" />
<script type="text/javascript">

</script>
the way JSF manage the params. The error, acdording to the message shonw by IE is in this line: curForm.elements['idVar'].value = null;
The code of the JSP is this:
<h:commandLink     actionListener="#{consultaEstadisticasMB.detalleEstadistica}">
     <f:param name="idVar" value="#{consultaEstadisticasMB.idColumna3}" id="idVar" />
     <f:param name="idMun" value="#{registro[0]}" id="idMun" />
     <h:outputText title="#{consultaEstadisticasMB.columna3}" id="itColumna3" value="#{registro[2]}" />
</h:commandLink>
Waht can i do? (Not using MyFaces, because I can�t do that)
Thanks for your answers!!

I have run into this same problem with javascript and the colon. I am not sure if the colon is a valid character for a javascript identifier (one would think the RI developers would have checked it out though!?!).
Anyway, my workaround is to search through the Javascript DOM for the widget you want to obtain a reference to, using part of its id. After all, you know its id, you just can't use it as a javascript reference. In your Javascript code, do something like:
    var inputWidgets = document.getElementsByTagName("input");
    var targetInput;
    for(var i = 0; i < inputWidgets.length; i++)
       var inputId = inputWidgets.id;
if(inputId.indexOf("yourInputId") != -1)
targetInput = inputWidgets[i];
break;
It's a lot of effort to just get a reference to a form widget....but it works (I pasted in the code and changed it a bit, so it might not work as is, but at least it demonstrates the idea).

Problem with IE and pubblishedIntoWall

Hi to all,
   i have a problem with InternetExplorer and CallBack
In my flex code i have :
flash.external.ExternalInterface.addCallback("pubblishedIntoWall", pubblishedIntoWall);
The javascript code:
function pubblishedIntoWallCarrello() {
        document.getElementById("composer").pubblishedIntoWall(1)
In both Firefox and Chrome the javascript works in the right way.
In internet explorer the function pubblishedIntoWall is not called.
Have some one got an idea of this problem?
Thanks for your time

Problem with JavaScript in URL iView

Hi,
I am facing a problem with javascript when i am trying to access my application through URL iView. In the javascript window.top is used to access the frames in the window. But the EP is not recognizing it as valid. what exctly the problem and please suggest me a solution.
Ashok.

Hi,,
thanks for the quick reply. But what i asked was different. I will put it in different way. I have deployed a application in Web Application Server and trying to access it through URL iView. My application is pure J2EE application with html,jsp and JS files. In javascript we used window.top property of the java script which is working fine MS IE. The problem is window.top is a IE specific property which is not having any equallent open standerd so EP is throwing a java script error. As I know the only possible solution for this problem is inherating IE rendaring capabilities to iView(i.e iFrame). is there any way to do that?

Problem with JavaScript in DPS

Hello,
i have little problem with one HTML page in DPS. We've created HTML form, which is formatting output with JavaScript and then passing to local mail client via mailto. It works nicely in Safari on desktop, it works in Safari on iPad BUT it don't work in DPS, when we use it as HTML content (frame on page where form is loaded). Unfortunately, there is no way how to learn what's wrong - on iPad it works, it's not working just in DPS (and it's not working in Viewer on desktop too).
Anyone have any idea what to do?
Script is fairly simple, it's my compilation of other works, because i'm not JS programmer, just i'm skilled with google-copy-paste... So there can be some VERY trivial error, but i don't know correct syntax...
very simple version of this form, which is not working in DPS (but everywhere else), is here
http://dl.optio.cz/mailtoExample.html
Thanks for any help!

Hello,
when used in DPS browser, it's working (as part of HTMLresources.zip). I don't know if this will help, but here is small game, which works correctly in DPS in web overlay. when you move any red circle, it will let you send results via email. But this is too complicated for my minimal skills.

Problems with SwingWorker and classes in my new job, ;), can you help me?

Hi all, ;)
First of all, sorry about my poor English.
I have a problem with Swing and Threads, I hope you help me (because I'm in the firsts two weeks in my new job)
I have two classes:
Form1: Its a JPanel class with JProgressBar and JLabel inside.
FormularioApplet: (the main) Its a JPanel class with a form1 inside.
I have to download a file from a server and show the progress of the download in the JProgressBar. To make it I do this:
In Form1 I make a Thread that update the progress bar and gets the fole from the server.
In FormularioApplet (the main) I call to the method getDownloadedFile from Form1 to get the File.
THE PROBLEM:
The execution of FormularioApplet finishes before the Thread of Form1 (with download the file) download the file. Then, when I call in FormularioApplet the variable with the file an Exception: Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException is generated.
First main begins his execution, then call to Form1 (a thread) then continues his execution and when the execution is finished ends the execution os Form1 and his thread.
How can I do for main class call the function and the Thread download his file after main class assign the file of return method?
How can I pass information froma class include an a main class. Form1 can't send to main (because main class made a Form1 f1 = new Form1()) any information from his end of the execution. I think if Form1 can say to main class that he finishes is job, then main class can gets the file.
I put in bold the important lines.
Note: My level of JAVA, you can see, is not elevated.
THANKS A LOT

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
iPad: Issues connecting to Wi-Fi networks http://support.apple.com/kb/ts3304
iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

Webcontrol problems with javascript

Hello,
the page I want to navigate making me problems in my webcontrol. The same page works fine if I go there manually with the Internet Explorer. I force webcontrol to use another IE version than default. I changed regedit >
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
and a new key for my application with value 2af8(11000)
If I do not force this version the used version in the webcontrol seems to be to old.
I think that my application does not use the settings of my IE because if I use IE manually it works.
I used Google and I can not find a property to force the webcontrol to activate javascript - it seems that I have to change this by the "global" settings.
Edit: I do not exactly know if its javascript. The error is a script error.
It does not help to suppress this errors - the page is not working correctly

Hello,
in the meantime I tried GeckoFX to solve the issue, but I get another problem later so I come back to the native webcontrol. To get help I will translate the error message because I can not attach a screenshot
"Scripterror
URL: http://www.transerv2000.de/DesktopModules/SNITNET_Metrix/js/rma_main.js
Do you want to continue? Yes / No"
Because I see the .js I think that this is an issue because of javascript.
If I navigate to this site and do some work I have no problems. This is why I think that the used IE in my webcontrol is having other settings?!
Please help and thanks alot.
Edit: If I supress javascript errors, I got not Messagebox but the content dont work - so I really think that it is a problem with javascript. As I said, if I use the IE as application the page works fine.

Problems with JSF and included subviews

Hi everybody,
I' ve got a problem with JSF and included subviews which makes me going
crazy. I've got no clue why my web-pages are represent wrongly. The only
tip I've got is that it must be connected with the kind I do include my JSF-pages.
When I use <%@file="sub.jsp"%> my pages are are represent right. When I use <jsp:include page="Sub.jsp" /> or <c:import url="Sub.jsp" /> ( mark: the usage of flush="true" or flush="false" doesn't matter )
my pages are represent wrongly.
The usage of tags like f:facet or f:verbatim were also included but didn't point to an solution.
I searched the whole Sun Developer Forum and some other web-sites for any solution for my problem but the given hints and clues didn't help. Now I'm trying to post my problem directly in Sun's Forum in hope to get help.
My environment is the following:

Hello Zhong Li,
many thanks for your post, but it didn't work.
My problem is that the JSF-Components im my included or imported
JSP-Pages does not accept any kind of style or styleClass for
designing. The components take over the informations for colors
but not for alignment.
When I take a look at the generated JAVA-Source in $TOMCAT/WORK/WEBAPP for my sub.jsp ( sub.java )
it seems that the resulting HTML-page would be presented correctly.
But later when I start the application via Firefox or Mozilla the html-sourcecode is totally wrong.
In my example I create a simple grid with 2 rows and 2 columns.
Both columns contains JSF-Outtext-Components and are included with div-tags.
The generated Sub.java shows that the text would be setted in the div-tags. Unfortunately the html-sourcecode represented by my browser shows that jsf-text is not setted in the tags but in the <h:form> tags. The div-tags are neither rounded by <h:form> nor containing the JSF-OutText-Components.
Any clue?
Many thanks Benjamin

AIR with JavaScript and AJAX (noob design issues)

Okay, so as the subject states, I'm a noob when it comes to designing an AIR app. My question is kind of two fold:
First, as a matter of design, I've got a main window that has several drop-down type menus "File", "Preferences", "Help" that kind of thing. My plan was to keep reusing the main window for each of my different screens (unless a pop-up/dialog type screen was called for)
Anyway, the application I'm writing will, in part, handle a database of patrons. So under one of the menus (File in this case) I've got a "Patron" option. Clicking on "Patron" fires a function called newPatron() which in turn calls my function ebo.displayScreen('patron.htm'). This latter function takes the filename passed in and reads that file then dumps it's contents out to the main screen.
So, my main window consists (in part) of the following html:
<body onload="ebo.doLoad();">
     <div id="content"></div>
</body>
then my displayScreen function looks like this:
function displayScreen(filename){
     var my = {};
     // get a handle on the file...
     my.file = air.File.applicationDirectory(resolvePath(filename);
     // get a handle on the stream...
     my.stream = new air.FileStream();
     //open the stream for read...
     my.stream.open(my.file, air.FileMode.READ);
     // read the data...
     my.data = my.stream.readUTFBytes(my.stream.bytesAvailable);
     // close the stream...
     my.stream.close();
     // update the screen (I'm using jQuery here)
     $("#content").empty().append(my.data);
So anyway, this works like a champ. I click on "Patron" from my file menu and the screen changes to display the contents of patron.htm.
Currently, patron.htm just contains the following:
<div style="text-align:left;">
     <input type="button" value="add" onclick="ebo.add(1,2);" />
</div>
<div id="result"><div>
ebo.add looks like this:
function add(a,b){
     var my = {};
     my.result = a + b;
     $("#result").empty().append(my.result + "<br />");
So, if anyone hasn't guessed by now, the code contained in the ebo namespace gets included on the main screen when the application loads, and my problem is that despite the fact that once the patron.htm file is loaded in the content div by clicking on the menu option, my button on that screen refuses to work. I've even tried just having the button do an alert directly,
<input type="button" value="add" onclick="alert('AIRRocks!');" />
but even that fails!
So, I added some code to the main page to test a button from there...
<body onload="ebo.doLoad();">
     <input type="button" value="add" onclick="ebo.add(1,10);" />
     <div id="result"></div>
     <div id="content"></div>
</body>
So, now when the main screen loads, I get an "add" button and when I click it the number 11 appears in the "result" div. When I click on the Patron menu option, the new html and javascript are loaded into the "content" div, but the add button in that area refuses to work!
What gives? I'm sure I'm missing something. So I guess the two questions are: is my scheme of loading new content into the main window by reading the contents of a file, flawed in some way? Or am I just missing something about making calls from this dynamically loaded content? It *looks* like it should work fine, but if I can't make javascript calls from the resultant content, then the concept is no good.
I realize this has been a somewhat long winded post, but hopefully it describes in enough detail the problem I'm having. I should maybe add that I've looked at what's in the DOM using the AIR HTML/JS Application Inspector and it looks like everything should work perfectly.
I hope someone out there can help me and might have the patience to explain where I've gone wrong. I might also mention that the only book I've read (or am reading) on AIR with JavaScript and AJAX is "Adobe AIR (Adobe Integrated Runtime) with Ajax: Visual QuickPro Guide"... it really hasn't covered aspects of what makes good design (like what's the best way to reuse the main application window to hold interactive content)... but anyway, there you have it.
Again, I hope someone can help me out.
Thanks!
Chris

Thanks for responding, Andy. I don't think I'm losing my namespace. That
thought had crossed my mind, which is why (and I thought I put this in my
original post) I tried putting a somple alert in the onclick event of the
button in my "patron.htm" file... but that simple alert doesn't even work.
:o(
Do you still think it's an issue with the namespace?

Problem with JFrame and busy/wait Cursor

Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I've had the same problems with cursors and repaints in a swing application, and I was thinking of if I could use invokeLater, but I never got that far with it.
I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread.

Problem with installing and running some applications or drivers

When installing and installing some items, towards the end of the installation I get this message:
/System/Library/Extensions/comcy_driver_USBDevice.kext
*was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update*
The end result is that some things do not seem to work properly, such as my HP printer. Would anybody have any ideas on how to fix this problem?

Thank you for your response. Originally, I had a problem with Airport and ended up reinstalling Snow Leopard. Since then, when downloading upgrades etc, such as HP printer drivers, iTunes etc., towards the end of the download when its running the script, I get this message: /System/Library/Extensions/comcy_driver_USBDevice.kext
+was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update+
Sometimes, the download hangs and is unable to complete. The main problem I've encountered so far with an application is when I use the printer to scan an image via Preview, it's blank: there's nothing there.

Problems with outlook and address book contacts: my outlook contacts had around 3,000 entries. Outlook duplicated by itself and now outlook and address book have each over 340,000. What should I do?

Problems with outlook and address book contacts: my outlook contacts had around 3,000 entries. Outlook duplicated entries and have now 340,000. I reinstalled microsoft office and, thus, outlook, and reinstalled mac OS X system and applications. While I managed to delete outlook contacts so that I can re-sync with my blackberry, the contacts at Mac Address Book were not deleted and still have over 340,000 entries. I do not mind deleting all contacts since I have back up, but I have not been able to delete them. Also, when I go at Address Book and try to delete or merge duplicated entries, the system takes forever and never ends because of such large amount of entries. Worse, when I do so I run out of RAM memory.
My Macbook pro is just 2 months old.
What should I do? Is there a way to delete my Mac Address Book without having the problem above?
Many thanks
Regis

Problems with Safari and Firefox (HTTP?)

Problems with Safari and Firefox (HTTP?)
On a laptop G4, 10.5.8 and Safari 5.02 I experience the following:
On the account of my oldest daughter everything works fine, i.e. wireless internet works and no problems with mail or safari.
On the same laptop, on the account of my other daughter, the wireless is OK, she can mail etc. But safari nor firefox works. It says: can’t find server (whatever site) and in the activity window it looks if safari tries to open files (in the safari preferences-folder) in stead of http. Same applies to Firefox, so maybe it has more to do with HTTP in general?
What goes wrong? What to do? I tried the following on the host terminal (tips from Apple)
defaults write com.apple.safari WebKitDNSPrefetchingEnabled -boolean false
and
defaults delete com.apple.safari WebKitDNSPrefetchingEnabled
but that did not help,
Nanne

I'm still wondering why it happens now at this moment in time...
PC does seem to be a bit odd & inconsistent, the few times I've tested with it, at least so far as we content filtering goes; and if I remember rightly, you're not the first to report previously ok settings suddenly preventing some or all internet until pc is switched off altogether.
It may work when re-enabled
