Re: Page Storage and serialization

[Lon Varscsak]

Thanks, I was getting hung up on page store and data stores.  I switched to
wicket 9 for this project and I'm using InSessionPageStore and that seems
to do what I want.  Thanks!

Page Storage and serialization

[Lon Varscsak]

Hey there,

I'm in a bit of a situation and could use some guidance.  I work with a
framework where I have problems with deserialization.  So I'm trying to
basically just make my app store pages in a cache that doesn't rely on
Serializable.  Is there some way to pull this off with stock Wicket?  I'm
looking at the page storing mechanisms and they all seem to be built off of
serialization.  What I'm thinking is just store pages in a memory cache (no
serialization/deserialization)...I know this isn't as efficient, but it's
what I'm used to in my old web framework and I can't find a good way to get
this other framework to deserialize the way I want (hard to explain).

Any tips would be appreciated.

Thanks,

Lon

Cayenne firing faults when it shouldn’t be (or at least I don’t think it should be)

[Lon Varscsak]

I have a situation where I fetched a large amount of objects (50k) and
prefetched a bunch of relationships…this all worked as expected (although I
didn’t realize that this set of data was that large at the time)…but what
caught my eye is that even though it pre-fetched the relationships it was
firing some of the those same relationship’s faults.  I _think_ they were
all to-one (not sure that matters), but something that I thought of.

Is faulting in any way tied to object cache and since the result set is so
large that some things have fallen out of cache and get re-faulted?

Re: ResourceStreamRequestHandler and page refresh

[Lon Varscsak]

Okay, cool.  I did see this, but one of the things I was perplexed about is
how to get an IResource into the AjaxDownloadBehavior at the time of
onClick.  I guess in onClick I could set an ivar to some resource and model
load from there.  Any other ideas?

ResourceStreamRequestHandler and page refresh

[Lon Varscsak]

Hey all,

I've got a Link that I use to generate and download a report.  I'm using a
ResourceStreamRequestHandler and
getRequestCycle().scheduleRequestHandlerAfterCurrent which works fine,
except that I was expecting my current request to finish as if it were a
regular link.  In this case, I'd want it to refresh the page I'm on, but it
doesn't do that.

Anyway to accomplish this?

Perfect, this is what I was looking for.  So if I wanted to hijack the

IP Authentication

[Lon Varscsak]

I have a need to build some apps (or mount points) to check if the source
is coming from an internal IP and if not, present the user with an
"unauthorized" request.  I know how to check client IP and what not, but
I'm not sure how to generate programmatically a simple WebResponse that is
just some text with a status code.

1) I'm currently using IRequestCycleListener to listen and then hijack the
response.  Not sure if this is the appropriate place.
2) How do you programmatically generate a response without implementing all
the methods of WebResponse.  At the point that the IRequestCycleListener
the response that is in the cycle already has content.  Basically I want to
throw that away and return "Unauthorized"/401.

Any thoughts or suggestions?

Thanks!

Performance issue (possible bug since 7.2.0…up to and including 8.0.0-M8)

[Lon Varscsak]

Okay, so here's the situation, I have a component where an Ajax request
displays a large table (1000ish rows).  It display fast, no problem, not a
great use of resources (not paginating), but ignore that for now.  I then
have another Ajax request where I tell the wicket component to not be
visible and refresh an area.  No problem so far (although slightly slow,
since it's not generating much html, should be faster).  Now EVERY Ajax
request that updates the same area (with the component not in the html)
takes a long time to respond (half second), even though it should be
returning in ms, because the html is pretty minimal.

I hooked it up to a profiler and found that it's spending a large amount of
CPU time in
MarkupContainer$MarkupChildIterator.refreshInternalIteratorIfNeeded(). I'm
not sure why it would be traversing the component hierarchy of the table
that's not even visible…but I don't know enough of the architecture of
wicket to really say…which is why I've come here. :)

I've gone back to 7.1.0 and can confirm that in that version this "problem"
does not exist.  The Ajax request is as fast as if I've never loaded the
large table.

So I've attached a link to a Quickstart showing the problem (currently
configured for 8.0.0-M8, but can be complied down to 7.0.0).  When loading
the page, first click the refresh link…this will essentially refresh all
the contents in an Ajax request and give you a sense of how fast it
_should_ be.  The table has not been visible yet, so there have been no
ListView items created yet.  Then click "show table", this will generate 2k
dummy rows and redisplay the area.  It's obviously slower because it's
generating 350k of html (but surprisingly fast :P).  Then click hide
table.  It takes about the same amount of time to hide the table as it does
to show it, which is odd, because the html being regenerated is the same as
if there were no table displayed.  Then go ahead and click "refresh" and
you'll see that refreshing a basically empty component is slow because it's
referencing all the components in the wicket hierarchy (
MarkupChildIterator.refreshInternalIteratorIfNeeded)even though they're not
visible.

Thoughts?  I recognize that the first response will be "don't display 1000
rows", but lets ignore that for now.

Thanks!

Re: Wicket 8 GA for production

[Lon Varscsak]

I agree with this wholeheartedly…I was just having this discussion with my
boss yesterday.  I do not understand (mostly) this drive to push stateless
frameworks (client or server).  Obviously your framework needs to support
stateless as to not waste resources, but almost every application I write
is complex enough that without servers side state, I’d spend more time
trying to figure out how to store state.

It’s one of the things I loved about Apple’s WebObjects and one of the
reasons I’ve moved to Wicket over other more “popular” java frameworks.

Stateless page to return JSON data

[Lon Varscsak]

So I was building a simple WebPage to return JSON data, but I’m surprised
that it’s creating a session.  The code is pretty simple, I’m just using
scheduleRequestHandlerAfterCurrent to return JSON content.  No real
components on the page and I set stateless hint to true in the constructor.

But when init() on the page is called, it ends up calling dirty(true) which
ends up creating a session to get the page manager.

I’m sure I’m missing something obvious…any thoughts?

Form validation and model objects not getting updated on failure

[Lon Varscsak]

Hey there, so I have a form with many textfields all of which have
validators on them.  In a situation where I’m creating a “new” record, all
the fields are blank.  I also have a DropDownChoice object with an
AjaxFormSubmitBehavior (“change”) attached.

If the user clicks “save” prematurely, obviously there will be a lot of
errors on the form.  Also if the first thing they do is choose an option in
the DropDownChoice some of the form values are invalid.  The problem that I
have is that it seems like even though some of the values (in this case the
form component bound to the drop down choice) are valid, those values don’t
make it into the model because of the other invalid values.

Is there a way to circumvent this?  I’m okay with fields that have invalid
values not making it into their model objects (makes sense most of the
time), but in this case I want some to not update and some to update.

Thanks for your time,

Lon

Re: Refreshing form after model objects changed

[Lon Varscsak]

It’s really not that complex.  The form has invalid input, something
happens and the model object changes the state of said input, the form does
not reflect the new model changes.  I was just hoping for something
automatic.

Re: Refreshing form after model objects changed

[Lon Varscsak]

Digging in a little deeper, I learned that if my data comes from the forms
model (which is not how I’m currently doing things), and then create a new
model, everything works as I’d expect.

So in my case, I have a bunch of FormComponents that use a PropertyModel to
do their work.  Rather than visiting all of the FormComponents and calling
modelChanged() is there a better way to do this?  I’m not so keen on
CompoundPropertyModel (although I can’t articulate why yet :P)…probably
because I may have more than one model for a given page.

So I’m thinking of a nested model for my object(s) storing them in ivars,
and then replacing those when I show.  I’m just not sure if there’s an
existing class that will let me use a model as a basis for another model
(not that that seems hard to write).  So I’m looking for what others are
doing.

Thanks!

Re: Refreshing form after model objects changed

[Lon Varscsak]

Yeah, I had convinced myself on the way home that it was a feature
too…until I thought about the model data having changed.

So I looked into the form.clearInput() (thanks for that tip) and the model
object is in a particular state that has field is hidden at the time I do
the clear.  So it’s that my model object has changed and my UI doesn’t
reflect the current state (because of this feature) once they make the
field visible.

It just feels like a little bit of an odd case (not that I know how it
would be better).  I guess I’ll switch to not reusing the component (which
is fine), I just think I’m going to bit by this more than once. :)

Refreshing form after model objects changed

[Lon Varscsak]

I have a scenario where I have a form and the user puts in a bad value in
FieldA, and then also puts in proper values in FieldB and FieldC.  FieldB
and FieldC never receive their values (in the model object), I’m assuming
because the form processing stops at the error for FieldA.  The user
dismisses the model (which just makes the component not visible and does an
Ajax refresh).

The user then goes in to edit the data again (same component, just made
visible and refreshed with an Ajax request).  Before the panel is shown the
underlying model object is swapped out with a new one (that has no values
in all 3 fields), however, when it appears the data is as it was
previously, including the unsaved values in FieldB and FieldC (from the
first pass).

This surprised me a bit (not that I’m anywhere near a wicket expert), I
would have assumed that since the model object changed that the form
components would refresh.  So in hacking around, I found that if I visit
all the FormComponents and call clearInput() on them, the form will display
the correct values (blank in this case).  Calling clearInput() on the form
itself has no impact (which also surprised me).

What’s the proper way to handle this case? I feel like while I have a
working case, it’s a little clunky.

Re: DropDownChoice with a different choice class than model class

[Lon Varscsak]

Yeah, I already had a renderer that was taking care of the conversion for
me, it’s just I was subclassing DropDownChoice whose generics are only 1
type (both choices and model value).  I ended up subclassing AbstractChoice
and copying methods (and modifying them to support model values and choices
being different) from AbstractSingleSelectChoice, which kind of sucks, but
does what I need. :)

DropDownChoice with a different choice class than model class

[Lon Varscsak]

Am I wrong to assume that DropDownChoice (and a few of it’s superclasses)
should be using the generic of  that AbstractChoice defines where T
is the class of the model object and E is the class of choice object?

It seems that from AbstractSingleSelectChoice up, it assumes that the value
from the model is the same as the choice.

In my case, the model object may be a string, but my choices and renderer
are rendering from a complex class.

Localizer in bundle

[Lon Varscsak]

Hey all,

How can I get a localized string (from a properties file) inside of a
library I have without the use of a Component.  I have a controller class
(nothing to do with components), but I’d like to have this class (In a
non-application jar) return an error message to the application localized
(with dynamic values), but I can’t see how to do it.  Localizer only allows
passing in a component (and not just any class).

Ideas?

Thanks!

“Duplicate” objects on a page

[Lon Varscsak]

I have a situation where I have a Save/Cancel button up at the top of the
page and also one at the bottom.  I’d love to reference the same wicket:id,
but I gather that’s not possible.  I attempted to clone the object
(WicketObjects.cloneObject), but then I think I’d have duplicate ids (can’t
set id outside of the class).

Any solutions to this problem?  I’d really rather not duplicate the
onClick’s (even though they mostly share common logic) if possible.

Thanks,

Lon

Trouble updating component when using markup inheritance

[Lon Varscsak]

Hey guys,

I’ve got a component (ComponentB) that subclasses from another component
(ComponentA).  In ComponentB I call a method on ComponentA that updates a
div (ajax) that wraps some content on ComponentA in addition to the
 (which is ComponentB’s content).  While this updates
correctly, if I have any links in the Child, no Ajax handlers are returned
in the ajax call, so the updated values are correct, but none of the links
work anymore.

If there are any links in ComponentA’s html, they will have the proper
handlers regenerated and called.

I have a quick start here that demonstrates the problem:
https://dl.dropboxusercontent.com/u/549221/test.zip

Any thoughts?

Thanks,

Lon

Re: Approach to changing value in input field before validation

[Lon Varscsak]

Well, the user is entering a part number (SKU) and there are times where
we’ve specified replacement SKUs.  If I find only 1, then I want to replace
and continue, but if I don’t, I want to continue the existing validation
and maybe it finds a valid part or maybe it gives the user a message.   But
if I replace the 1 and it’s now in a discontinued state, I need to fail
validation and let the user know.  It’s not a typical e-commerce app,
actually it’s a large CRM system, so there are times where I have to do
unusual things to meet the users needs.

The current application (desktop) leaves SKUA in the textfield, but gives
you the validation messages for SKUB (assuming it fails).  I felt that this
was more confusing that swapping the input and then showing the user the
replaced value along with the validation message that belongs to the new
SKU (B)

Approach to changing value in input field before validation

[Lon Varscsak]

Okay, so I have a need…I’m sure I’m going to get “why are you doing that?”,
but I have this need regardless and here’s what it is… :D

User inputs “VALUEA”, I want to look up something in the database for
“VALUEA”, and if conditions are met, replace that with “VALUEB” and
continue with validation for the new value.  However, the only way I can
see to do this would be to update the *rawInput* value, which I do not have
access to as a subclass (it’s private).

So instead, I tried writing a converter, and it generally behaves as I want
(it validates “VALUEB”), however if there’s a validation error on “VALUEB”
the rawInput is still “VALUEA”…so it’s a little confusing to the user.

I’m not sure that using a converter is the “right” approach, but it’s the
closest I’ve come to a solution.

Thoughts?

Thanks,

Lon

Adding a row to a ListView (or any repeater) programmatically for Ajax update

[Lon Varscsak]

Hey guys, I have a large table and when the user clicks the “new” button, I
don’t want to refresh the entire table.  I saw a post about using
javascript to create the empty TR element, with the ID that wicket would
use, and then have wicket just refresh that id.  Sounds great, except I’m
struggling with how to pull that off.

I don’t see exposed API for me to add (or get back) a new list item into
the ListView (which would let me get it’s markup id for an update).  I
think I can pull this off with my own subclass, but before moving on to
that I wanted to make sure I wasn’t missing something basic.

Thanks for any info,

Lon

Wicket Validation

[Lon Varscsak]

Hey guys,

I have some business logic where when the set method is called, it first
validates the value.  In finding a “bad” value, it then throws a custom
validation exception.  We use this pattern all over the place.

Is there some way to handle this situation so that it’s a valid wicket
validation error?

Thanks for any tips.

AjaxFormValidatingBehavior on component

[Lon Varscsak]

Hey guys, I may be missing something here, but if I do:

TextField textField = new TextField("keyCode", new PropertyModel<>(
order, OrderHeader.SOURCE_KEY_KEY));

textField.add(new AjaxFormValidatingBehavior("blur"));


*  add(textField);*

I get an error “*AjaxFormValidatingBehavior should be bound to a Form
component or a component that is inside a form!*”

If I change it to:

TextField textField = new TextField(“keyCode", new PropertyModel<>(
order, OrderHeader.SOURCE_KEY_KEY));


*  add(textField);*

textField.add(new AjaxFormValidatingBehavior("blur"));

It works.  Basically the AjaxFormValidatingBehavior is expecting to find a
form in it’s parent, but it’s parent hasn’t been assigned yet.

Is this expected behavior?

Thanks,

Re: DropDownChoice and Object/Property

[Lon Varscsak]

haha, sorry…here’s another pass:

So the objects that are in the list are called ShipMethod and it has a
“description” which I want to use for display, and an “id” which is the
thing I want stored in the Order object.  But with the property model and
ChoiceRenderer as I have it, it’s expecting to push a ShipMethod object
into the Order object’s “shipMethod” attribute, but it’s not modeled that
way.  In the Order object I just want to store the “id” from ShipMethod in
“shipMethod”.

DropDownChoice and Object/Property

[Lon Varscsak]

Hey all,

Is there a way to have a DropDownChoice use a complex object (think ORM
class) as it’s list, but get/set the Model’s value as the ID instead of the
complex object?

So for:

new DropDownChoice<>(“shipMethod”, new PropertyModel<>(OrderPage.this
.getOrderController().order().shippingHeader(), “shipMethod"), new
ListModel<>(shipMethods), new ChoiceRenderer<>("description", "id"))

It puts in the ORM object’s toString into the “shipMethod” column and I
want it to put in the value for “id” from the renderer.  Additionally, I
want it to get it’s initial value from the “id” value instead and convert
it to the ORM object (from shipMethods list).

Hopefully this makes sense. :P

Re: HTTP ERROR:500

Hey Martin, actually I’m not running in Prod mode, but development.  The
behavior for the output is different between 7.1 and 7.2 (which is the
error message I sent).  In 7.1, I don’t see an error message on the page at

I definitely saw the exception, I guess it wasn’t clear to me what I had

HTTP ERROR:500

[Lon Varscsak]

Hey all, I’m new to wicket and I got this horrendous error earlier today:


I had NO idea what it meant. :P  I was able to debug it and see what was
left in queue, and that reminded me that I hadn’t finished the html for a
new component I had added in the constructor.  My question is, isn’t there
a better way to explain to the developer what’s going on?  It would be
super helpful to newbs like me. ;D

Just a thought.

Thanks,

Lon

How to include resources from project (jar)

[Lon Varscsak]

Hey guys,

I’m new here and I’m trying to get a URL for a resource (css) located in
/src/main/resources/.  I can across CssResourceReference, but if I use
“resources/whatever.css” or “/resources/whatever.css” the file isn’t
found.  If I use "../../../../whatever.css” it works.  I’m assuming because
it’s located in the default package I’ve got to drop down into that.  Is
there 1) a better way to do this? or 2) a way to do it that’s more
predictable, like something that says start at the root package?

Thanks for any insights!

-Lon

P.S. — I’m not deploying with a war, but as a jar with embedded Jetty.
