Dynamic HTML page with Wicket?
Hello, I have an old application to re-write. It is a provisioning tool for different companies, and each company can create their own main page which tells a little about themselves, contact information etc.. This functionality is done by using a text box, and letting the user write free html, and then the code just renders the html.. If I wanted to do this with Wicket, what would be the most efficient way? Is it better to not use Wicket to do this? And use PrintWriter? Or is there a better way to have the user create the html, and store it to a file, and then feed it in to let Wicket create the page each time? Thanks! -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Dynamic-HTML-page-with-Wicket-tp4666769.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

Pom.xml errors in Wicket
Hello, I am getting an error:
Missing artifact org.apache.wicket:wicket:pom:6.15.0:compile
This is when I try to update to 6.15.0 from 1.5.5 .. I also get it for
slf4j.. Here are the two errors together:
7/8/14 11:01:51 AM CDT: Missing artifact
org.apache.wicket:wicket:pom:6.15.0:compile
7/8/14 11:01:51 AM CDT: Missing artifact
org.slf4j:slf4j-api:jar:1.6.4:compile
I can't understand why. It does this even if I change it to 6.12.0 for
instance. What can I do to troubleshoot this, I don't get what would cause
this issue. Here is my pom..
properties
wicket.version6.15.0/wicket.version
jetty.version7.4.0.v20110414/jetty.version

I don't understand why it keeps asking for it. If I take it out it's still
looking for it, and when I change to slf4j.version1.6.4/slf4j.version
I get more errors:

Ah okay, sorry about that. That def makes more sense now. I wasn't 100% sure
how to even read the pom but it makes a lot more sense now.

Wicket version 6.15 referring to older Jar
I have gotten all the latest jars installed for the Wicket 6.15. I can verify this in the Maven Dependencies directory. For some reason, I feel it is still pointing to an older version of Wicket. I am getting strange errors with the add method from the MarkupContainer. Using the quick-start example, in the HomePage class I am getting an error with: add(new Label(message, If you see this message wicket is properly configured and running)); The error is: The method add(Component[]) in the type MarkupContainer is not applicable for the arguments (Label) Not sure why it is using Component[] as a argument and not Component... childs as I am used to.

Re: calling downloadLink.onClick() directly
Thanks Martin,
I guess what I am more curious in, is how come when I call the
downloadLink.onClick(), or do:
public void onPostProcessTarget(AjaxRequestTarget target)
{
final File file = excelFile;
IResourceStream resourceStream = new FileResourceStream(
new
org.apache.wicket.util.file.File(file));
ResourceStreamRequestHandler handler = new
ResourceStreamRequestHandler(resourceStream, file.getName());
handler.setContentDisposition(ContentDisposition.ATTACHMENT);
getPage().getRequestCycle().scheduleRequestHandlerAfterCurrent(handler);
I get the ajax error as shown above thread. It's only on onClick() call, or
when
getPage().getRequestCycle().scheduleRequestHandlerAfterCurrent(handler);
is called..

calling downloadLink.onClick() directly
Hello, I currently am using a downloadLink to export a csv file to the user.
What I am currently doing is using a worker thread to handle the creation of
the csv file while an AjaxSelfUpdatingTimerBehavior updates the GUI of its
progress.. Then at completion the intent is to call downloadLink.onClick()
to invoke the behind the scenes work and get the user the dialog box
automatically to download the file. I get everything running fine until
downloadLink.onClick() is called I get an ajax error:
Wicket.Ajax.Call.failure: Error while parsing response: Error: Invalid XML:
��ࡱ�;�� ...`��Page 1�����=Bems_ID
First_Name Middle_NameLast_Name User_Status
it looks like the csv file is being outputted to the ajax debugger.
What is the best way to invoke the onClick method automatically of the
DownloadLink class?
Here is a snippet of what I am doing:
private void setupDownloadLink()
{
IModel excelFileModel = new AbstractReadOnlyModel()
{
public Object getObject()
{
if(excelFile == null)
{
excelFile = new File(Error getting File);
}
return excelFile;
}
};
auditDownloadlink = new DownloadLink(auditDownloadlink,
excelFileModel)
{
public void onClick()
{
downLoadLinkClicked = true;
if (newSearchWasInitialized)
{
newSearchWasInitialized = false;
if (!extractionIsRunning)
{
worker = new
CreateExcelExtractionWorker();
thread = new Thread(worker);
thread.start();
extractionIsRunning = true;
excelFile = null;
return;
}
}
if(!newSearchWasInitialized)
{
if (!extractionIsRunning)
{
super.onClick();
}
}
}
};
auditDownloadlink.add(new Label(excelLabel, Excel));
auditDownloadlink.setOutputMarkupPlaceholderTag(true);
auditDownloadlink.setDeleteAfterDownload(true);
auditDownloadlink.setCacheDuration(Duration.ONE_SECOND);
auditDownloadlink.setVisible(false);
findUserForm.add(auditDownloadlink);
}
Here basically when the user selects the button, it starts the worker
thread.. Then when completed, the AjaxSelfUpdatingTimerBehavior will call
the onClick() method, where in turn after each check is made then
super.onClick() is called to process the downloading of the file as normal:
public void onPostProcessTarget(AjaxRequestTarget
target)
{
System.out.println(isRunning);
if(!extractionIsRunning)
{
if(downLoadLinkClicked)
{
System.out.println(refreshed);
progressModel.setObject(Extraction
to Excel file complete. Click
Download);
auditDownloadlink.addOrReplace(new
Label(excelLabel, Download));
target.add(findUserForm);
target.add(progress);
stop(target);
System.out.println(isStopped);
downLoadLinkClicked = false;
auditDownloadlink.onClick();
}
}
}
};
progress.add(progressUpdateBehavior);
progress.setOutputMarkupId(true);
Do I have to attach it back to the requestCycle?

How does Wicket know when to make a new session?
My company uses a webgate to verify the user before redirecting to the application. Wicket works fine outside of this webgate and retains one user session for each tab opened in the browser or new browser window. But when accessed through this webgate, wicket creates a new session and expires the old one. So anything running in the original opened tab gets terminated. What are some things I can look for to work around this through Wicket? Thanks. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-does-Wicket-know-when-to-make-a-new-session-tp4664756.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Detecting if page is opened in another tab
Thanks Martin,
This seems to be the solution, but isn't working as it should.
I tried this:
add(new AjaxNewWindowNotifyingBehavior()
{
/**
*
*/
private static final long serialVersionUID = 1L;
@Override
protected void onNewWindow(AjaxRequestTarget arg0)
{
System.out.println(called//.);
String message = You already have an instance
of Bulk Loader running.
Please view from the current opened window.;
setResponsePage(new BulkLoadPage(message));
}
});
And the method: onNewWindow never even enters on a new instance of the page,
while one is currently opened in another tab.

Detecting if page is opened in another tab
Hello, I am running a thread that displays a list of results to the page. I want the user to be able to open the page only in one browser tab. If they open it in another tab then it will give an information message and not let them. I have a worker thread running, so I only want the list being displayed in one tab, and not updating multiple instance of the same page throughout the session. I was able to do this setting a flag in the session, but then there comes the issues if the user totally exits out of all pages and then reopens the application and goes to the page. Then the user is locked out of the page entirely. I tried browsing the pageMap and it seems the page still exists in the pageMap even if the user closes all tabs of the application. So that idea didn't work.. I was able to check this because I would open an instance of the page and check the pageMap to see if it already exists in there somewhere. Then I closed any tabs with the application opened in it, and then opened the page in a new tab. The page still existed in the pageMap. What is the best way to iterate through and check if there is another active instance of a page attached to the application (beyond just sitting in the pageMap and not currently active) I need to do this since there doesn't seem a way to check if the page was closed. I tried using detach(), but I have an AjaxSelfUpdatingTimer, and this calls detach() numerous times.. so that wouldn't work either.

Re: Issue on multi-threaded page when opening another tab in browser
Hi Martin,
I originally had the List as an instance variable for the Page but when I
would open a new browser tab, the original page would crash and a
nullpointerException would be given because the page reference lost
reference to the object.
So now I create in the page constructor in instance of BatchLines and pass
it along through method parameters.
The thread is started from a method called in the constructor. Here is the
def of this method:
/
* Method: beginProcessing
*
* Invokes workerThreads
*
* returns: void
/
private void beginProcessing(List batchLines)
{
fullReportDwnLoadBtn.setVisible(false);
try
{
csvFileCreater = new CSVFileCreater(LOADER_CSV_FILE_NAME);
if(turnOnLoader)
{
BatchLoaderProcessingThread threadJob = new
BatchLoaderProcessingThread(stringList, batchLines);
loggerThread = new Thread(threadJob);
loggerThread.start();
}
else
{
BatchDeleteProcessingThread deleterThreadJob = new
BatchDeleteProcessingThread(stringList, batchLines);
loggerThread = new Thread(deleterThreadJob);
loggerThread.start();
}
} catch (IOException e)
{
// TODO Auto-generated catch block
log.error(Inside beginProcessing() throws error: +
e.toString());
BatchProcessPage.this.error(An error has occurred
starting creation of
CSV file);
}
}
Here is the definition of the thread class:
class BatchLoaderProcessingThread implements Runnable
{
List stringList;
List batchLines;
public BatchLoaderProcessingThread(List stringList, List batchLines)
{
this.batchLines = batchLines;
this.stringList = stringList;
}
@Override
public void run()
{
processLine(stringList, batchLines);
loaderFinished();
}
}
processLine is a method that is part of the Page class.

Issue on multi-threaded page when opening another tab in browser
Okay, so I have an issue that I have finally narrowed down to multi-threading issues. I have a loader page that has a worker thread to process a csv file and store the results into a list declared as: List batchLines = Collections.synchronizedList(new CopyOnWriteArrayListBatchLine()); Each BatchLine object is a row in the csv file that was processed. I also have a pageableListView on the page that uses the BatchLine List to update itself. I use a AjaxSelfUpdatingTimerBehavior which will update the pageableListView every two seconds. The problem is, if I am on this page in one browser tab, and the workerthread is running, and the page is updating, and then at the same time I open another instance of the application in another tab of the same browser, the thread loses focus of this List. I know this because I print out the size of the list, and it stays the same when I open a new instance. I first had the List batchLines Global, but now I pass it as a parameter to keep it local to each method. When it was global, I had to mark it transient for serializable issues. The issue with this is the page would crash when I opened a new tab with another instance of the application. What can I do to prevent this? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Issue-on-multi-threaded-page-when-opening-another-tab-in-browser-tp4664552.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Error in Modal opening two diffrent instances of Wicket applicaiton.
Thanks Paul, I am using new sessions and the problem seems to be okay locally, but not on the server. So I noticed that on the server (through the access portal we use) it forces a new session per tab. So the original issue with the modal window I thought I have found the session issue to be the culprit, but now even running locally I am getting page expirations when running locally. This happens on a page that I redirect to using a setResponsePage, and while this is up, and I open a new application instance inside of a new browser tab, the original tab's page expires right away. What should I be looking at to make sure this doesn't happen. I have been searching all over and I can't seem to find any real solutions to this issue. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Error-in-Modal-opening-two-diffrent-instances-of-Wicket-applicaiton-tp4664418p4664521.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: Error in Modal opening two diffrent instances of Wicket applicaiton.
Okay, so I was able to try some more scenerios, and it looks like if I have one instance of the application open in one tab, and open a modal window and now do anything.. Then open another instance of the application but not even click on anything, and go back to the first intance and just hit cancel on the Modal which calls a window.close(target) then I get a page expired error..

Error in Modal opening two diffrent instances of Wicket applicaiton.
Hello, I am having an issue when I have my application opened in two separate
tabs in IE or FireFox.
Here is the problem:
I have a page called User, and in this page you can open a Modal window to
search for a user. Once a user is found, you select it, and the Modal window
closes, and that User object and its attributes is used and displayed to the
User page.
The problem is if I have tab open on the User page and run a search in the
Modal window for another user, and while this is taking place, I open
another tab and goto another instance of the application and to the user
page, and then perform a search using the same scenerio.. The latest opened
instance of the application will return the search results to the page just
fine; and the first instance of the application and the running search will
close the page, and nothing will happen, or the page will reset itself
loading the defaulted information. This only happens when I open a new tab
and instance of the application while a current instance is already running
a search in the modal window of User page. If I open two different sessions
of the application before running any searches, then run a search in each
session everything is fine.
Some background:
The modal class uses the PageReference passed in through its constructor. I
use this to interact with the calling pages variables. Once the modal window
closes using window.close(target); the calling class will continue its page
update via:
modalReference.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback()
{
public void onClose(AjaxRequestTarget target)
{
..make changes to page here.
Here is what happens just before the modal window closes:
public void onClick(AjaxRequestTarget target)
{
setCurrentUserFromLite(item.getModelObject());
((UserPage)modalWindowPage.getPage()).addUserInformation(selectedUser.getLastName(),
selectedUser.getFirstName(),
selectedUser.getMiddleName(), selectedUser.getBemsid(), );
((UserPage)modalWindowPage.getPage()).setFindUserFromModal(true);
((UserPage)modalWindowPage.getPage()).setCurrentUser(selectedUser);
window.close(target);
}
Any ideas what is happening? Or is there a way to maybe check to see if the
same functionality is being used in another instance and prevent the user
from running a search?

Re: MultiThreading issues with Wicket.
I have temporarily fixed it by first loading the lines into a string ArrayList and just read from that list.. I don't really see any latency issues, so maybe this can be considered a good alternative? -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/MultiThreading-issues-with-Wicket-tp4663325p4663389.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
Re: MultiThreading issues with Wicket.
Great catch Paul. I have made the changes reccommended. However, I read the
file into the arrayList using the main thread, and then use the worker
thread for processing. I don't think the ArrayList is being modified during
this time, but just incase something is happening beyond my knowledge under
the hood that will need this or in the future I will be modifying the
contents of the Array, I have made the neccessary changes as you suggested.
The only thing I noticed is after my worker thread finishes, my
AbstractAjaxTimerBehavior in the main thread seems to take about 10 seconds
or so before it performs a component update on the List, even though I have
it set to 1.
I don't get any errors anymore though, and the whole list does get processed
now.
here is my settings for AbstractAjaxTimerBehavior:
resultsUpdateBehavior = new
AbstractAjaxTimerBehavior(Duration.seconds(1))
{
/**
*
*/
private static final long serialVersionUID =
-4790160167650215915L;
@Override
public void onTimer(AjaxRequestTarget target)
{
if (!loaderIsRunning !deleterIsRunning)
{
target.add(loaderListContainer);
resultsUpdateBehavior.stop(target);
target.add(progress);
// progressUpdateBehavior.stop(target);
}
else
{
target.add(loaderListContainer);
target.add(progress);
}
}
};
add(resultsUpdateBehavior);

Re: MultiThreading issues with Wicket.
Thanks Paul I really appreciate your time and efforts to assist me in this issue. I have implemented your reccommendations and I was still getting the same issues (This seems to only be with the larger file as well) and I thought it was the AjaxSelfUpdatingTimer but instead it looks like the page was just refreshing due to a stalePageException: count: 15469 SSAID: Access6 Stopped, total line size = 15469.0 Stopped, total line size = 15469.0 Jan 02 16:54:37 WARN RequestCycleExtra- Jan 02 16:54:37 WARN RequestCycleExtra-Handling the following exception org.apache.wicket.core.request.mapper.StalePageException Jan 02 16:54:37 WARN RequestCycleExtra- I seem to get this when I try to load upload the same file again after the first instance has finished. I am going to try and run a file that takes a bit longer to process to see if I still get the same errors. At the moment the file finishes processing at about a second, I do add a printline inside my timer method and it shows it has stopped well before the actual repaint of the table, so this is what makes me thing the actual final repaint is due to the StalePageException. This exception only occurs though on the consol when I try to upload a new file, or click on any of the buttons on the page. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/MultiThreading-issues-with-Wicket-tp4663325p4663397.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

MultiThreading issues with Wicket.
Hello, I am having an issue when using a worker thread to process a csv file. I have asked the same question here: http://stackoverflow.com/questions/20747605/requestcycle-goes-null-when-using-a-separate-thread and I wanted to post here as I feel there are not many Wicket programmers there. The main issue seems to be when I process a large csv file I get a read error. But if I process a smaller one I do not. Here is the stack trace: java.io.IOException: Read error at java.io.FileInputStream.readBytes(Native Method) at java.io.FileInputStream.read(FileInputStream.java:220) at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:264) at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:306) at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:158) at java.io.InputStreamReader.read(InputStreamReader.java:167) at java.io.BufferedReader.read1(BufferedReader.java:185) at java.io.BufferedReader.read(BufferedReader.java:261) at java.io.BufferedReader.fill(BufferedReader.java:136) Dec 30 13:14:31 ERROR BulkLoadPage-java.io.IOException: Read error at java.io.BufferedReader.readLine(BufferedReader.java:299) at java.io.BufferedReader.readLine(BufferedReader.java:362) at au.com.bytecode.opencsv.CSVReader.getNextLine(CSVReader.java:266) at au.com.bytecode.opencsv.CSVReader.readNext(CSVReader.java:233) at com..wicket.BulkLoadPage.processLine(BulkLoadPage.java:547) at com..wicket.BulkLoadPage.access$0(BulkLoadPage.java:532) at com..wicket.BulkLoadPage$BatchLoaderProcessingThread.run(BulkLoadPage.java:1294) at java.lang.Thread.run(Thread.java:662) I basically have a listView that is being updated by the main thread using AjaxSelfUpdatingTimer - set to update every 1 second. The worker thread which is an inner runnable class uses the methods of the main class, and updates the arrayList which is also stored in the main class and used by the listView. I was originally getting a requestCycle error, which seemed to be resolved by commenting out my feedbackPanel error message inside my catch. That error seemed to be produced from a read error produced by the reference to the CSVReader. The file being read in contains many lines. I believe around 15k. Every line has the same data which I copied and pasted just to test a large file. The file seems to work fine when it is less than 2k.. so I am thinking maybe it is a sychronization issue or some issue with data interleaving. I had designed this page not knowing there would be issues with larger files using a thread.. there is a lot of functionality and there is no issues with a small file as stated.. just larger ones. The only job of the thread is to call a method from the main thread. That method loops through and processes the CSV file, and when that ends.. the thread dies. Should I be using local variables in the thread? Or what are some steps I can take to troubleshooting this error? Or is there a better way I should approach this to having a worker thread process results while the main thread uses a listView to display results. A dataView was reccommended and I will try that as well, but I am not sure if I can use a worker thread with that or not.

How to clear autoComplete textfield in Wicket after submit?
I'm having issues clearing the input of a autoComplete Textfield.. For some
reason whenever I call target.add(reference to AutoCompleteTextField);
my input values are null...
So basically, I can clear the referenced string the input is stored in, but
everytime I call an ajaxupdate it nulls.
I tried both ajaxButton, and AjaxSubmitLink. Both get the same reactions. I
have a button to submit the input from the textField.
Code:
form wicket:id=autoCompleteForm
input wicket:id=autoCompleteTextField size=20/
button width:100px wicket:id=selectRoleBtnSelect/button
/form
private void autoCompleteForm()
{
findRoleForm = new FormVoid(autoCompleteForm);
findRoleForm.setOutputMarkupId(true);
addOrReplace(findRoleForm);
field = new AutoCompleteTextFieldString(autoCompleteTextField,
new PropertyModelString(this,autoString))
{
@Override
protected IteratorString getChoices(String input)
{
if (Strings.isEmpty(input))
{
ListString emptyList = Collections.emptyList();
return emptyList.iterator();
}
ListString choices = new ArrayListString(10);
for (final Role role : rolesList)
{
final String roles = role.getRoleName();
if (roles.toUpperCase().startsWith(input.toUpperCase()))
{
choices.add(roles);
if (choices.size() == 10)
{
break;
}
}
}
return choices.iterator();
}
};
findRoleForm.addOrReplace(field);
findRoleForm.addOrReplace(new AjaxSubmitLink(selectRoleBtn,
findRoleForm)
{
protected void onSubmit(AjaxRequestTarget target, Form? form)
{
System.out.println(here1 + autoString);
if(rolesList != null autoString!= null)
{
if(rolesList .size() != 0)
{
for(int i=0; i rolesList .size(); i++)
{
System.out.println(here2 + autoString);
if(rolesList
.get(i).getRoleName().equals(autoString))
{
role = rolesList.get(i);
roleInformation.addOrReplace(new
Label(roleNameTxt, role.getRoleName()));
roleInformation.addOrReplace(new
Label(roleAliasTxt, role.getRoleAlias()));
roleInformation.addOrReplace(new
Label(roleOwnerTxt, role.getRoleOwnerId()));
roleInformation.addOrReplace(new
Label(roleStatusTxt, role.getRoleAccessStatus()));
roleInformation.addOrReplace(new
Label(roleCategoryTxt, role.getRoleCategoryName()));
roleInformation.addOrReplace(new
Label(roleDescriptionTxt, role.getRoleDescription()));
roleInformation.addOrReplace(new
Label(roleValidityTxt, role.getRoleValidityStatus()));
roleInformation.addOrReplace(new
Label(roleNumUsers, ));
//add adOrReplace(findRoleForm);
autoString = ;
target.add(field);
target.add(roleInformation);
currentRoleSelection = null;
target.add(rolesDropDownChoice);
break;
}
}
}
}
}
}).add(getIndicatorAppender());
}

Re: How to clear autoComplete textfield in Wicket after submit?
To add: The autoCompleteTextField input field clears the first time, but when I try it again. The string: autoString will be null. So if you choose your selection on first attempt (from the search list provided), hit select button, it gives you the correct string and clears. But when you do it for a second time, selected a provided value, the autoString will be null.. and will not get the input value assigned to it. -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/How-to-clear-autoComplete-textfield-in-Wicket-after-submit-tp4661268p4661269.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
updating table on main page after modal window is closed..
here
userPageFindUserModal.setWindowClosedCallback(new
ModalWindow.WindowClosedCallback()
{
public void onClose(AjaxRequestTarget target)
{
System.out.println(ssaIDLISTCON);
userInformation = new WebMarkupContainer(userAttributeTable);
userInformation.setOutputMarkupId(true);
addUserInformation(test, Massey, J, 1234512, Enabled);
target.add(userInformation); } });
When I close my modal window I want to update the contents of the calling
page... but it doesn't work.When I refresh the page however it works, but
the ajax isn't giving me access to the current page components.. How does
this work with a modal window? Is the target for the modal window? or for
the parent pages instance?Any ideas? Thanks!

That's the example I was originally using, and I did everything like that but my ajax doesn't work upon return calling the webmarkupcontainer, but theirs does.
