Re: Quickstart Problems

[Dan Haywood]

Hi Maxim,

with causeway.apache.org (which uses wicket under the covers) we've taken
to keeping our quickstarts [1],[2] as a separate github project ... makes
it easier for us to maintain out of band, and for users to contribute
issues.  Just an idea.

Thx
Dan

Re: Wicket MVVM

[Dan Haywood]

Regarding the annotation-heavy soup (nice phrase!) - in theory you could
remove them because the programming model is completely open for
customisation ... it consists of a set of so-called FacetFactory's that
introspect the domain classes (or anywhere else you want to specify the
semantics) and build up the domain model.  In fact, most folk tend to use
the associated .layout.xml file for UI hints rather than the @XxxLayout
annotations, because making changes doesn't require a recompile.  In theory
this could be done for other annotations too, if that's your preference.

Regarding pluggable persistence - we support JDO and JPA and in the past
someone spiked neo4j and mongodb, so that's definitely doable.

But this isn't really the forum to talk too much about Apache Isis, we have
a mailing list or a slack channel if you want to learn more.

Re: Wicket MVVM

[Dan Haywood]

There is a plan to add OData support to isis.apache.org, so that a
collection of objects could be opened in (and perhaps edited through)
Excel, say.

Re: Urgent help

[Dan Haywood]

I doubt that Martin (Grigorov) will be able to help much based on this
description, Mukesh... there's not enough info here.

I would recommend you put together a small quickstart sample application on
github somewhere, which demonstrates and explains clearly the issue that
you are having.

There's a framework called NoWicket [1] that is a half-way house between
"raw" Wicket and Apache Isis; might be worth taking a look at.

Re: Problems with update of wicket from 8.0.0 to 8.1.0

[Dan Haywood]

Use mvn dependency:tree to capture your actual classpath before and after
the upgrade; this should help you identify where the clash is in your
classpath.  You can then use exclusions or dependencyManagement to pick up
the correct version.  I use IntelliJ and the "Maven Helper" plugin is
invaluable for finding conflicts; I think that Eclipse has something
similar built-in.

How allow select from a disabled field

[Dan Haywood]

The Apache Isis project [1] uses Wicket for its main viewer, and we
recently had this question [2] on our mailing list is:

I believe it was mentioned once in another thread that selecting text
(and so copying) from a disabled field doesn't work in Firefox on
Windows. Since a week or two it's not possible on a lot of Chrome
installations of our users either, probably due to a Chrome update. This
really is a big problem for our users because we share a lot of
configuration data for internet access and telephony services and
copying data makes sure they don't make mistakes while configuring their
systems.

Would it be a problem to use the read only attribute instead of the
disabled attribute? That would be an easy fix.


Martin G suggested a possible fix using CSS, but unfortunately to no
avail.  Since this presumably could impact all Wicket users, the suggestion
[3] was to re-raise the question here.

So, are there any thoughts on this?  Is there any way to enable select text
for a disabled input field for both latest Chrome and Firefox?

Thx

Re: Exceptional upgrade experience 6.14.0 - 6.17.0

[Dan Haywood]

+1 for providing that feedback; seconded!

We use Wicket within Apache Isis, and it too uses plenty of the same
components, and I can't recall any problems either, all the way through the
various 6.x releases.

 Hi all-

 I wanted to take a minute to thank all the Wicket Project contributors—
 committers, users and the community as whole. We just completed a seamless
 upgrade from 6.14.0 to 6.17.0 and had to make *zero* code changes.  This is
 extremely impressive for any software project, and especially notable due
 to the fact that we use all sorts of complex Wicket features, extend
 components, and implement custom extensions in our Integrated Console
 product.

 Our Wicket feature list includes, but isn’t limited to:
  * Modules
  * Events
  * Modals
  * Ajax everywhere— Input, Fields, Validation
  * Custom Authorization Strategy
  * Sortable Tables
  * Feedback panels
  * Breadcrumb bar

Apache Con EU Budapest, 17~21 Nov 2014

[Dan Haywood]

Hi folks,

Just to make you aware, in case you weren't already, that Apachecon EU 2014
is running in Budapest in Nov 17th to 21st [1].

There's a great variety of talks there, from a whole variety of ASF
projects;
surely something for anyone.  Wicket is particularly well represented, with
three talks from
Martijn (Dashorst) on Wicket [2], [3], [4].  More details here [5].

If you'll indulge me in a bit of cross-promotion, you might also be
interested in another Apache
framework that is a big user of Wicket, namely Apache Isis [6].  There's a
couple
of sessions on Isis, too [7], [8].

So do see if you can find the time to attend, would be great to meet up.

Cheers
Dan Haywood

Re: Wicket 6.0.0: RenderStrategy.REDIRECT_TO_RENDER and missing FeedbackMessages in ComponentFeedbackPanel.

[1] https://issues.apache.org/jira/browse/WICKET-4773

Wicket 6.0.0: RenderStrategy.REDIRECT_TO_RENDER and missing FeedbackMessages in ComponentFeedbackPanel.

[Dan Haywood]

We're using RenderStrategy.REDIRECT_TO_RENDER (ie redirect after post
strategy; in 1.4.x this was working fine and our FeedbackMessage's were
rendered correctly against their reporter using ComponentFeedbackPanel.

Having upgraded to 6.0.0, the messages no longer appear.

Investigating, it seems that the FeedbackMessage#detach() causes reporter
to be set to null, meaning that the ComponentFeedbackPanel's filter makes
no match on the subsequent render.

Changing the RenderStrategy to REDIRECT_TO_BUFFER causes the feedback
messages to appear.

This looks like a regression to me?  But perhaps there's something I'm
meant to do that isn't in the 6.0.0 migration notes?

Any advice welcome!

Announcing WicketObjects v0.1

[Dan Haywood]

Hi all,

I'd like to announce a new open source (ASLv2) project to help develop 
Wicket applications - Wicket Objects.  This is an integration between 
Wicket and the Naked Objects framework.  The idea is that you can 
develop full webapps just by writing domain objects pojos, and Wicket 
Objects (with a little help from NOF) then renders your objects 
automatically.  You can then use your Wicket skills to customize the UI 
as need be.


There's some screenshots and a quick start on my blog 
(http://danhaywood.com) and there's a website too 
(http://wicketobjects.sourceforge.net).  To get started all you'll need 
is SVN and MVN.


I'm looking for feedback, and I'm also hoping that some of you smart web 
UI guys (not my strongest suit!) might be interested in helping me 
develop it up to a v1.0 release.


Thanks for reading,

Cheers
Dan Haywood

Re: Re: Can I develop without recompiling/restarting after every change?

[Dan Haywood]

have you tried JRebel?  I've not used it myself, but there was an 
interview on JavaPosse recently, sounds like it'd be an ideal fit for 
any Wicket developer.

the easiest way to do this is to use
the Start class (Start.java) from the
quickstart to run an embedded jetty instance in your
IDE.  then, if you run
it in debug mode, it will hotswap any possible changes (and
tell you if you
must restart if it's an incompatible change)

how to handle clear input for custom FormComponents

[Dan Haywood]

Hi all,

I've developed a custom FormComponent (by subclassing 
FormComponentPanel) to act as a reference from one object to another (eg 
a Customer to an Address), but am having problems figuring out how to 
handle clear input (ie, if the user hits the cancel button on the form).


To explain a little further, the FormComponent is called EntityLink, and 
renders the reference (eg the Customer's homeAddress) a hyperlink.  I 
have a button on the EntityLink panel allowing the user to perform a 
search for other objects of the correct type, and then select it.  Doing 
this updates the EntityLink component, with a pending value (ie of the 
new homeAddress).  If the user hits the OK button, then the pending 
value is copied over to the domain object (ie to the Customer's actual 
homeAddress property).


In the cancel button's onSubmit() method I'm calling 
getForm().clearInput(), which seems to use a visitor to call 
clearInput() on all child FormComponent's.  The FormComponent's 
clearInput() method seems only to set the rawInput to a constant 
(NO_RAW_INPUT), which looks like it's a magic value of some kind when 
the form component is actually rendered - all rather low level.


I think what I'd like is to eagerly capture this clearInput so that I 
can reset my EntityLink's hyperlink back to the original value and 
discard the pending value.  However, clearInput() is unfortunately 
marked as final so there doesn't seem to be any easy way to capture this.


Looking at other implementations of FormComponentPanel (eg 
DateTimeField) they are really very little other than wrappers around 
simple FormComponents, so they don't offer any real clues.


Can anyone help me here, then?

Thanks
Dan

Re: how to handle clear input for custom FormComponents

[Dan Haywood]

I found a way to make this work (though I worry the solution might be a 
little fragile).


Basically, I'm overriding getInputAsArray() in my wrapper EntityLink, 
delegating to a hidden text field; then, in onBeforeRender() I check if 
there is input, and if not then infer that clearInput must've been 
called on and so zap the value of the hidden text field.


If anyone cares to look at the code, it's on sourceforge:

http://wicketobjects.svn.sourceforge.net/viewvc/wicketobjects/trunk/main/viewer/src/main/java/org/starobjects/wicket/viewer/components/entitylink/EntityLink.java?revision=78view=markup

Thanks anyway
Dan

how to make a BookmarkablePageLink enabled when its parent component is disabled?

[Dan Haywood]

I have a FormComponentPanel (called EntityLink) that holds an image, a 
hyperlink (a BookmarkablePageLink) and a hidden text field holding the 
serializable value of the reference.


Initially I want the form is in read-only mode and so I have disabled 
all of its form components.  However, I'd like the link to be enabled.


Looking at the source code, Wicket calls isLinkEnabled() to determine 
how to render the link; this in turn calls isEnabledInHierarchy().  My 
problem is the latter is (correctly returning false) but I want the 
former to return true.  Both methods are final, however.


I'm obviously tackling this incorrectly - so what would be the Wicket way?

Thanks
Dan

Re: how to make a BookmarkablePageLink enabled when its parent component is disabled?

Hi Pedro,
That was my first instinct, to override isEnabled(), but it turns out 
that it is isLinkEnabled() that gets called, in the onComponentTag() 
method (ie when rendering).


So, no joy there.

Any other suggestions, anyone?

Hi, you can override the isEnable method and implement your rule, like:

new BookmarkablePageLink
{
  boolean isEnabled() {
return form.getState() == allowedState;
}
}

or you can add the link higher in the component hierarchy, don't as an 
form child.
