Re: Updating a Dynamic Image with AJAX (and JFreeChart)
Hi there,
is JFreeChart your only possible approach? Check out flot integration
from wicketstuff-core.
It draws nicer charts and you can update datasets sending json object
and redraw it by js.

I couldn't override getResourceState of DynamicImageResource as it new Resource
state uses variable from DynamicImageResource eg format. Instead i copied
DynamicImageResource class and made my own version of it and modified the
getResourceState() get method. When I changed the drop down I was expecting it
to call the geImageData but it wasn't calling it. Could you please advice.
Here is the modified method.
protected synchronized ResourceState getResourceState()
{
return new ResourceState()
{
private byte[] imageData;
private final String contentType = "image/" + format;
@Override
public Time lastModifiedTime()
{
if (lastModifiedTime == null)
{
lastModifiedTime =
DynamicImageResource.this.lastModifiedTime;
if (lastModifiedTime == null)
{
lastModifiedTime = Time.now();
}
}
return lastModifiedTime;
}
@Override
public byte[] getData()
{
// here is what I made the change.
imageData = getImageData();
return imageData;
}
@Override
public String getContentType()
{
return contentType;
}
};
}
From my Image Class I called the copied version of in getImageResource() {
return new DynamicImageResource(){
public class TugboatChartImage extends NonCachingImage {
private int width;
private int height;
public TugboatChartImage(String id, JFreeChart chart, int width, int
height){
super(id, new Model(chart));
this.width = width;
this.height = height;
}
@Override
protected Resource getImageResource() {
return new DynamicImageResource(){//my copied version of DynamicResouce
@Override
protected byte[] getImageData() {
JFreeChart chart = (JFreeChart)getDefaultModelObject();
return toImageData(chart.createBufferedImage(width, height));
}
};
}
}

Look at the source of the DynamicImageResource class. The getResourceState
method does something like (sorry for the lame pseudocode) 'if image data is
null then save and return value of getImageData else return the previous image
data'. So its gonna call your getImageData() method once and save the value.
This falls in line with the super class's (DynamicWebResource) javadoc that
says:
very useful for things you generate dynamically, but reuse for a while after
that. If you need resources that stream directly and are not cached, extend
WebResource directly and implement Resouce.getResourceStream() yourself.
It has nothing to do with HTTP caching, which it looks like you're trying to
solve with your headers, but server-side caching. Anyways... in this case,
getResourceStream of WebResource ends up calling getResourceState of
DynamicImageResource. All you need to do is is override getResourceState (and
therefore kind of overrides the behavior of getResourceStream) of your
DynamicImageResource and ensure that it doesn't cache the result of
getImageData() and you should be set.

I have same situation. I'm not able to refresh my image. But if i view the
image i do get refreshed image
Here is my code. Based on my dropdownchoice it should make new Jfreechart
and the image should refresh. I couldn't get it working so i wrapped the
image with in a span but it still doesn't work. TugboatChartImage extends
NonCachingImage . Can any one point out what I'm doing wrong
Chart chart1 = new Chart(this.getString(column1.toString()), "Date",

Ok. I came up with something similar based on the assumption: models
do not change during render.
I made a ModelLatch that caches the model value after onBeforeRender
and frees the latch at onDetach.
The problem is that there is no "onBeforeRender" event and one must
implement it for each container at least and for components that need
it and are ajax updated without their parent container:
public class ModelLatch implements IDetachable {
private boolean latched;
private boolean strict = true;
/**
*
*/
public void onBeforeRender() {
this.setLatched(true);
}
/**
* @see org.apache.wicket.model.IDetachable#detach()
*/
public void detach() {
this.setLatched(false);
}
/**
* @param
* @param
* @param dataTypeModel
* @return IModel
*/
public >
IModel getInstance(
DataTypeModel dataTypeModel) {
return new LatchModel(dataTypeModel);
}
/**
* @param latched the latched to set
*/
public void setLatched(boolean latched) {
this.latched = latched;
}
/**
* @return the latched
*/
public boolean isLatched() {
return latched;
}
/**
* @author Martin
*
* @param
*/
private class LatchModel implements IModel {
private IModel rootModel;
private boolean cached;
private T cache;
/**
* @param rootModel
*/
public LatchModel(IModel rootModel) {
this.rootModel = rootModel;
}
/**
* @see org.apache.wicket.model.IModel#getObject()
*/
@Override
public T getObject() {
if (isLatched()) {
return getCachedValue();
}
return rootModel.getObject();
}
/**
* @return T
*/
private T getCachedValue() {
if (cached) {
return cache;
}
try {
return cache = rootModel.getObject();
} finally {
cached = true;
}
}
/**
* @see org.apache.wicket.model.IModel#setObject(java.lang.Object)
*/
@Override
public void setObject(T object) {
if (isLatched() && isStrict()) {
throw new IllegalStateException("Strict latch does not allow

}
rootModel.setObject(object);
}

CompoundPropertyModel
Hello.
I have a "Person" class, describing a person, which has a member
"credentials" of type "Credentials" (username/password).
I tried to make a registration page in this way:
Page
{
super();
Person person = [create a person with empty credentials];
Form form = new Form("form", new CompoundPropertyModel(person));
add(form);
form.add(new TextField("familyName"));
form.add(new TextField("givenName"));
form.add(new TextField("credentials.userName"));
form.add(new TextField("credentials.passWord"));
// also add a submit button
}
And now when I push the "Submit" button, it outputs this error:
org.apache.wicket.protocol.http.PageExpiredException: Cannot find the
rendered page in session [pagemap=null,componentPath=0,versionNumber=0]
I like the idea of compound object model, and I wouldn't like to deprive
myself from using it just because of this strange error...
Can you give me a hint on what have I done wrong in the code above?
Re: CompoundPropertyModel
Do both Person and Credentials (and everything else Person holds on to)
implement Serializable?
Watch the logs to see if there are serialization errors. It's a problem of
the page not being in the session - which means it either didn't make it
there or the session is somehow gone.

Re: CompoundPropertyModel
Hi, Jeremy.
No, the log contained only this error...
But to be honest, although it didn't fix the error, your advice is still
valuable, because not all of the classes were Serializable.
And you know what?
I think I'll reinstall my application server.
I used Glassfish 2 before, and this time I tried Glassfish 3, but it
appeared to be a bitch...
It hangs oftenly and operates strangely...
So maybe it somehow messes with the sessions...
I'll install Glassfish 2 back then, when I have more time for this (maybe
tomorrow), and then I'll post the results here.
Thanks for your reply.

Re: CompoundPropertyModel
Try running your project in Jetty for development (you can use the Maven
quickstart to help you get started). It's usually much easier to get
running and see what's going on. It also allows for very easy on-the-fly
changes and reloading.

RE: CompoundPropertyModel
Kolya,
2 things:
1) If you still have the old setup:
Try stopping server, deploying your stuff to it, starting server.
I've had issues with redeploying at runtime (hot deploy) with Tomcat
(which is what Glassfish is based on). This is where Jeremy's advice to run
Jetty is a good idea.
2) Make sure that you refresh the form in your web browser before you try to
enter data and submit. Wicket needs to do stuff to that form before you can
submit it and if you keep same browser open between deployments, you are
sending data back to wicket that it knows nothing about, so it blows up with
pageexpired.
The fact that you don't get serialization errors in the log (if it wasn't
serialized) is b/c it didn't get that far yet, so problems are elsewhere.
Hope this helps,
- Alex.

You have a point, but I've been using Idea for... 6+ years now. These guys are very sales oriented. They added GWT support as a point release, like it was a no big deal. When they see there's a demand - they move on it. And if they can add a new popular framework for the launch - they just may, to make it sell better. They are in a war with Eclipse and "we got that and it's better" has been their selling angle.

and then on my EditableQuestionPanel.java I have :
AjaxLink up = new AjaxLink("up") {
@Override
public void onClick(AjaxRequestTarget target) {
target.addComponent(parent);
Template template = templatemodel.getEntity();
template.moveQuestionUp(question);
tf.store(template);
}
};

Modal window (1.4.1) and IE - Slow load times
Hi, I am using version 1.4.1 of wickets. P Contents of a Modal Window take extremely long time upto 10-20 sec to load on Internet Explorer 8. FireFox or Chrome on the same machine are really fast. with load times of 2-3 sec on a slow connection. Any one else seen this issue or has suggestion around fixing it. thanks, Ed _ Windows 7: It works the way you want. Learn more. http://www.microsoft.com/Windows/windows-7/default.aspx?ocid=PID24727::T:WLMTAGL:ON:WL:en-US:WWL_WIN_evergreen:112009v2
Re: Intellij9 integration
What do you mean that the current one shows up? I haven't updated WicketForge to work with IDEA 9 because I'm not on IDEA 9. Feel free to submit patches. Right now WicketForge does everything I need it to do, so unless I start using Wicket more often or it doesn't meet my needs, I'm not really inclined to spend my limited free time on it.

Re: AutoCompleteTextField in 1.4-SNAPSHOT
Hi,
This was a big help for me in getting what I wanted to do. It works really
good except for one problem. When the form shows up with a non null empty
object, the autocomplete field has the class name for the object in it,
i.e., "com.michni.search.bean.urll...@c1853". Once I load an object in the
form works fine.
Here is my code:
form = new Form(
"form", new
CompoundPropertyModel(
new
GUIBeanInventoryItem()));
IAutoCompleteRenderer urlLinkRenderer
= new AbstractAutoCompleteTextRenderer()
{
private static final long serialVersionUID = 1L;
@Override
protected String getTextValue(UrlLink urlLink)
{
return urlLink.getUrl();
}
};
autoCompleteUrl = new AutoCompleteTextField(
"urlLink",
new
CompoundPropertyModel(new UrlLink()),
urlLinkRenderer)
{
private static final long serialVersionUID =
-5590853972046975757L;
@Override
protected Iterator getChoices(
String valueLike)
{
try
{
List urlLink = dao...
return urlLink.iterator();
}
catch (Exception e)
{
throw new RuntimeException(e);
}
}
};
form.add(autoCompleteUrl);
In the code I have made sure that the UrlLink in GUIBeanInventoryItem is not
null and that urlLink.getUrl() returns "".
I have solved this problem with other items before but for some reason can't
seem to solve it now.
Appreciate any help.
Thanks.

Does your page have a lot of links on it? On Sat, Nov 14, 2009 at 6:36 PM, Ed _ wrote: > > Hi, > > I am using version 1.4.1 of wickets.
