DropDownChoice does not push value into Model
Hi All,
http://apache-wicket.1842946.n4.nabble.com/file/n2323809/Code.txt Code.txt
I have a drop down choice control on the search panel and its selected
choices are pushed to the model only once or the first time.
Please have a look at the attached code:
As part of this code, I noticed that when I uncomment the following line,
the drop down choice works every time.(as it is supposed to)
public void initialise(String id){
//cpm.getObject().setStudy(searchCriteria);///Set the search criteria object
back in order for status to be filled in the next submit/search
}
However, this will not resolve my issue, because if I refreshed the study in
the model when the details page is loaded, the problem re-occurs.
Not sure why this is hapenning, I tried to debug as much as I can, all i can
get to is, when i re-set the model's study instance after the search results
have arrived , then it works. If I do not, then it fails to capture the
value from DDC.
Thank you again
Cheers
Niv

James
Thanks for pointing it out. Later in the code I have added, so the study
object/instance in the initial model should be in synch right? Correct me if
I am wrong. Let me also think about this point u made. But yeah do let me
know if i have made a mistake.
cpm = (CompoundPropertyModel)this.getModel();reset the
original one
Cheers

Re Wicket Web Beans
Hi Would like to know if some one has used Wicket Web Beans in their wicket projects? One of our requirements is to add fields at runtime and be able to render it on the front end. So in this case , I have no control of building the panels for some fields that are 'yet' to be created and to infer what UI component(textfield, drop downs, radio box) should be rendered when I try to view those fields on the front end. Also will I be able to add validation rules to these fields at the same time the field is defined? I am using Wicket as the primary framework for the web layer and hibernate for the backend. I am hoping that this toolkit will be helpful in addressing this requirement. If anyone of you have used this toolkit would like to hear about your experiences. I am yet to embark on this path but in the meantime welcome your thoughts.

Re: DropDownChoice does not push value into Model
James
Could you please clarify this for me, I noticed is that with PropertyModel
usage in the above context.
I have to define one(PropertyModel instance) for each of the form component
explicitly, like so
1. Model studyModel = new Model(new
StudyModel());/Top level Model
In the Form:
I associate the studyModel above in the constructor and
Model pModel = (Model)getModel();
2. firstName = new TextField("studyName",new
PropertyModel(pModel.getObject().getStudyName(),"studyName"));
// I am manually telling it to navigate to a property ..thought it will be
nice if its automatic based on the expression
I am unable to create a single instance like
PropertyModel propertyModel = new PropertyModel(studyModel,
"study");
And then use propertyModel instance for each component.
Am I missing something here?
Thanks again
Niv

Re: DropDownChoice does not push value into Model
Hi James
Point(s) noted. I have got something going here and it is working but is
this what you meant? Please see attached code and do bear with my questions.
The variable studyReference which is the one that is wrapped within a
PropertyModel, remains or maintains the same reference even if the object
model is changed. So that is the key I suppose not to change the study
reference bound to the DDC any time and we wrap this in a property model.
Still have to get to grips with Models.
Thanks for the help
Cheers
Niv

Re: Asynchronous File Uploads
Thanks mate, I will investigate more on this, but can you elaborate it a little bit? I can think of the following 1. When the application starts up, the servlet will be loaded up. 2. In its init(), I would have to create a process that is more like a daemon and waits for it to be requested or invoked. 3. From the GUI, actor uploads a file - this has to delegate the request to the servlet.Which then does the job Am i on the right track?

Re: How to Update contents of a child component?
Sorry for the delay in response. I had fixed this issue and it was to do with my model. The Multiselect was not properly bound to a model. Infact I started using Palette control which is very good. And as for hiding and unhiding I found that sometimes just using setOutputMarkupId does not work all the time but using the above as you suggested the setOutputMarkupPlaceholderTag(boolean) works. Might post a thread on why and what the difference is between them.

Application of setOutputMarkupPlaceholderTag and setOutputMarkupId
Hi All I want to get this clear can someone let me know the behavior when we say setOutputMarkupPlaceholderTag and setOutputMarkupId. I found that, when I have a WebMarkupContainer for a component set to true initially and set the markupContainer to setOutputMarkupId(true). Now when I on an event I set the markupContainer's visibility to false. This hides the component. So far its good. Clicking another button I want the hidden panel to be visible and when i set the visibility to true and attach the markupContainer to the ajaxRequest, it does not repaint it and I got an error saying the component was not found. I changed it to setOutputMarkupPlaceholderTag and this time it works. I understand that Wicket does not have any reference to the component if we used setOutputMarkupid but why is this and when do we use the methods? Thanks for time Niv -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/Application-of-setOutputMarkupPlaceholderTag-and-setOutputMarkupId-tp2543555p2543555.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: SV: Application of setOutputMarkupPlaceholderTag and setOutputMarkupId
Hi Thanks for your thoughts. It is clearer now. Re-iterating from what you mentioned, my understanding is that when 1. "toggling invisibility via Ajax you need to use the placeholder tag" - 2.and we don't toggle visibility and want that component to be re-painted then we need setOutputMarkupId.

Set with PageableListView
Hi
I have a question related to using a collection (Set) within a
PageableListView. At runtime I get an exception
java.lang.ClassCastException: org.hibernate.collection.PersistentSet cannot
be cast to java.util.List
at org.apache.wicket.markup.html.list.ListView.getList(ListView.java:177)
The entity structure is like this
public class Subject{
String firstName;
Set phones;
}
I guess it expects only a List type object. I can work around this by
converting the Set into a List and then provide it but felt somehow this is
a limitation. How can I work with generic collections?
Any thoughts much appreciated
thank you

Re: SV: PageableListView to work with Set
So I gather from your response that I should use a list type object only. Since PageableListView uses it for indexing,sorting etc. Am I right then to convert either the entity to use a List or on the front end to map from a Set into a List.

Re: Wicket-Hibernate Related LazyInitializationException
Hi Dan,
I guess you were right with the thought process -
nivs wrote:
>

I noticed that when I navigated, it was only when the PhoneType which was an
entity (if not a collection on Phone) of Phone; when it was rendered threw
the exception.
public class Phone{
String phoneNumber;
PhoneType phoneType; //This one
}
So in the initial fetch, i got back 10 items and the List view rendered 5 of
them. The OpenSessionInViewFilter closed the session after I rendered 5
Phone items along with PhoneType. When i hit the next page button, since I
resorted to pulling the items of the Model(CPM), when it came to PhoneType
it threw the exception. The Set was available since I had manually
iterated them in the DAO, so that was not a problem.
Apologies for not pondering deeper from your thoughts. So now I fetch items
for every pagination this opens a Session now I need to optimize it in terms
of hitting the back end.
Mm well...thank you one and all for your thoughts. I still have to get
around how I can add multiple phone numbers using this design.
Many thanks again
Niv

Re: DatePicker to pick a year
Hi
If your getting the date format error from the Model side and it is
expecting a timestamp , then you might get that issue.
Are you using a TimeStamp field or pure date?
If I wanted only to store date in the backend without timestamp details my
model has to be decorated like
@Temporal(TemporalType.DATE) //This is important
@Column(name = "DATE_OF_APPLICATION", length = 7)
public Date getDateOfApplication() {
return this.dateOfApplication;
}
If for instance it was
@Temporal(TemporalType.TIMESTAMP)
It will fail validation based on the format.
Hope that helps
