Re: [Wicket-user] Updates within Panels in datatable

2007-08-01 Thread salmas


Hi Igor:

I cannot use the AjaxSubmitButton because I need to change the button's
model dynamically and this functionality is broken in Wicket 1.2 and I can’t
use the 1.3 beta because my company doesn’t want to use beta software for a
production release. I ended up using a regular Button and then updating the
table using an AJAX Target in the buttons onSubmit method. Please do let me
know if you have a better suggestion for what I can do here.
I tried 
ReuseIfModelsEqualStrategy strategy = new 
ReuseIfModelsEqualStrategy();
table.setItemReuseStrategy(strategy);

but this did not help. Do I need to create a custom strategy? If so what
should I do in it?

[Wicket-user] Updates within Panels in datatable

2007-07-31 Thread salmas


I have a datatable in which each row contains two panels. In one panel I have
a textfield and a radio button and in the other panel I have a button. So
there can be many textfields and buttons. When the user clicks the button in
panel 2 in one of the rows I need to read the values in the textfield and
radiobutton. In the buttons I have 
button.setDefaultFormProcessing(false);
So that onSubmit is called instead of the form processor. I have two issues:

- Even though I do nothing in onSubmit (which I know does get called) the
table is reloaded (button.getRequest() shows the request for the page to
reload). I'd like to stop the auto redraw and do an AJAX update from within
onSubmit instead, I am not sure how to stop the table reload when the button
is clicked.
- from within onSubmit() in panel2 the textfield and the radio button in
panel1 show their original values and not the values that I typed in prior
to pressing the button. The widgets have PropertyModels. To load the panels
I overrode public void populateItem(Item item, String componentId, IModel
model) in the table columns and then added the panels where appropriate.
What can I do to update the data in panel1 when the button in Panel2 is
clicked?

[Wicket-user] Is it possible to update a single row in a table?

2007-07-27 Thread salmas


I have to mimic an application which was written using javascript/XSLT in
which changes in a table affecting single rows are managed by updating only
the affected row(s). I believe that this is done by surrounding the row in a
span. Is this possible in wicket? I am using a Datatable.

Thanks

Re: [Wicket-user] Is it possible to update a single row in a table?

2007-07-27 Thread salmas

I have the exact same issue as the poster in the threads you sent. When I add
the repeater item to the AjaxTarget I get

java.lang.IllegalArgumentException: markupId cannot be empty

It works if I add the entire table to the target. It looks like you changed
things to fix this? I am using wicket 1.2.6 and wicket extensions 1.2.6. Do
I need a newer version?

[Wicket-user] navigating up from a frame

2007-07-18 Thread salmas



I am within the right frame of a frameset. The frameset has a tree in the
left frame. When the user clicks most of the links in the tree I want to
refresh the right frame. However, sometimes I want to navigate to a
frameless page (tree gone and show another frame in the app). I don't know
that I need to do this until I am inside the right frame and check a
setting. I should do this automatically and not have a user click a link or
something. When I do setResponsePage(MyPage.class);  from within the right
frame only the right frame refreshes. How can I replace the entire frameset
with MyPage.class?

Thanks

 so you dont want to append target=top to the link but decide this after
 link has been clicked?
 
 toppagerequesttarget implements requesttarget {
   private final Class? extends Page pageClass;
   respond(requestcycle rc) {
 rc.getresponse().write(htmlheadwindow.top.location='
 +rc.urlfor(pageClass);+';/head/html);
   }
 }
 
 then instead of setResponsePage(MyPage.class) do
 getRequestCycle().setRequestTarget(new toppagerequesttarget(MyPage.class);

Re: [Wicket-user] Textfield inside RadioChoice

2007-06-20 Thread salmas

Thanks, Igor, I switched to radiogroup/radio, however I still have issues
because I want to add the textfield to just a few of the options, my options
should look like

tr wicket:id=options
td
input type=radio wicket:id=workflowoption /input
/td
td
option name
/td
/tr

for some of the options but then others might look like

tr wicket:id=options
td
input type=radio wicket:id=workflowoption /input
/td
td
option name
/td
td
input maxlength=30 size=15 name=amount
wicket:id=amount /
/td
/tr

It looks like the radiogroup assumes that the markup is a template, if I
add the textfield to one
item then I must add it to the rest. I suppose I could use different panels
for each item but that seems so long winded for what I am trying to do. Any
suggestions?

However, the HTML is still escaped despite the

Does setEscapeModelStrings(false) not work in radioChoice widgets?

Re: [Wicket-user] Wicket 1.2.6 Development mode serialization checks and remote EJB's

2007-06-07 Thread salmas

It's not a case of an unknown reference causing the not serializable
exception. I know which object is not serializable and it is the concrete
proxy object created by WebLogic for my remote EJB. I ended up checking if I
was in development mode and then using a transient variable and then using a
another variable which is not transient when the app is running in a
production environment. I was hesitant to simply mark the EJB as transient
in case it caused issues in the production environment. Thanks all for your
replies, they helped confirm that there wasn't a workaround other than
marking it transient.

Root cause:

The EJB implements javax.ejb.SessionBean which extends the serializable

So it seems that I cannot use EJB's in wicket pages, (I am doing this
indirectly through service locaters to decouple the pages from the back
end). Any advice about what to do in this situation would be appreciated.
Currently I am running in deployment mode since this avoids the checking.
I
have given some thought to marking the EJB transient in my service

Eelco, I realized that you are recommending using Spring or looking up the
bean on the fly some other way but I am working for a place where Spring is
not part of the approved stack and they have an established way that
access to EJB's is coded. I am a contracter here and I have to do things
exactly how it has been established by the architecture team. I will forward
your comments to them so that they can see the advantage of your approach,I
am sure they will be interested in the suggestion.

It's not a case of an unknown reference causing the not serializable

using a
another variable which is not transient when the app is running in a
production environment. I was hesitant to simply mark the EJB as
transient
in case it caused issues in the production environment. Thanks all for
your
replies, they helped confirm that there wasn't a workaround other than
marking it transient.

But there is. You can turn the check off, even for development mode.
See IDebugSettings#setSerializeSessionAttributes[1]

What you probably want in the end though, is a construct like
@SpringBean or just look the bean up right at the moment you need it
without holding the reference.

It would be a simple thing to look up the bean in each method in the service
locater as versus keeping a reference. However, this is not how the existing
service locaters here have been coded and they've been clear about wanting
the new stuff to mimic the old stuff.
The best way to solve the issue would be to get rid of EJB altogather since
the usage requirements of the project are pretty light but I'm not here to
change the world (none of these arguments would be easy), just to get their
project coded for them as per their requirements. They are going to be
maintaining it so I suppose it's fair to code it exactly like the existing
code.

Not really. I mean a @SpringBean *construct*, like you can find in the
Spring integration project. That project generates proxies for every
@SpringBean annot found. These proxies are light and serializable, and
internally hold a transient reference to the actual spring bean. When
serialized, the spring bean instance is discarded; the proxy will
locate it again when it is called.

You said you can't use annotations, so that trick wouldn't go here for
you. There used to be a project[1] (now only for 1.2.x) that used
commons attributes[2] for the same purpose, but we're not maintaining
it for 1.3 anymore (though it is stored as a wicket-stuff project
now[3]).

Alternatively, you can just locate the bean just in time. Are you sure
you need to keep a reference to it in your component(s)? And consider
that *if* you need a reference, it's probably per-request (so you'll
want a new one when a new request starts). If that is true, you can
just set the reference lazily (get it when you actually access it),
and null it in the components onDetach method (override that method;
it will be called when a request is handled) so that it won't be
serialized.
