not serializable exception

2015-11-19 Thread Ciocoiu Elvis 
Hello,

After upgrading to wicket 6.21.0 I've get a strange serialization error
when adding the debug bar to ajax target. I do this on every ajax event in
development and it worked until today. The stacktrace extras:

Caused by: java.lang.RuntimeException: An error occurred while getting the

Re: Ajax download stops AjaxSelfUpdatingTimer

2015-01-26 Thread Ciocoiu Elvis 
Hello again,

Thank you for your hints. Ajax debug shows nothing interesting. It seems it
has to do with
 target.appendJavaScript("setTimeout(\"window.location.href='" + url +
"'\", 100);"); from AjaxDownload. If I comment this the timer works but not
file is downloaded. I refreshed manually the component with the attached
AjaxSelfUpdatingTimer and after the download finished the behavior's
property 'hasTimeout'  is true.
If i manually
call target.appendJavaScript("setTimeout(\"window.location.href='" +
getCallbackUrl() + "'\", 100);"); in an ajax behavior (after the download
finished) the timer is back to normal.

Do you have any ideas?

Thank you.

Re: wicket portlet in Liferay 6.2

2014-07-08 Thread Ciocoiu Elvis 
Maybe BookmarkableListenerInterfaceRequestHandler should be handled also in
PortletRequestHandler similar to how ListenerInterfaceRequstHandler is
encoded (the BookmarkableListenerInterface... now is just ignored and
mapHandler returns the url without encoding it for portal environment).

Anyway, thank you for your suggestions.

Re: wicket portlet in Liferay 6.2

2014-07-08 Thread Ciocoiu Elvis 
If i use
Application.getPageSettings().setRecreateMountedPagesAfterExpiry(false) my
AjaxLink works but I\m not sure about the implications. Is the
Component.urlFor(...) implementation in wicket > 6.13 the correct one?

Thank you

Re: wicket portlet in Liferay 6.2

2014-07-08 Thread Ciocoiu Elvis 
I think I found the problem ... in wicket 6.13

Component.urlFor(final Behavior behaviour, RequestListenerInterface
listener, final PageParameters parameters)

the decision to use BookmarkableListenerInterfaceRequestHandler
or ListenerInterfaceRequestHandler is different from wicket 6.12 where only
isStateless() was called. In my case the BookmarkableListener maps to the
wrong url. Any idea?

Thank you.

In 6.10, 6.11, 6.12 the url is rendered ok. In 6.13, 6.14, 6.15, 6.16 the
url is wrong.

Re: wicket portlet in Liferay 6.2

2014-07-08 Thread Ciocoiu Elvis 
Seems that in 6.10.0 to 6.12.0 the url for my AjaxLink is ok

http://localhost:8080/web/guest/welcome?p_p_id=test_WAR_wicketportalportlet_INSTANCE_2JbV4Gjuyvej&p_p_lifecycle=2&p_p_state=normal&p_p_mode=view&p_p_resource_id=/test/%3F0-1.IBehaviorListener.0-refreshTimeLink&p_p_cacheability=cacheLevelPage&p_p_col_id=column-1&p_p_col_count=1&_=1404812714838

Starting from 6.13.0 the url is

http://localhost:8080/web/guest/?0-1.IBehaviorListener.0-refreshTimeLink&_=1404812884161

Any idea what change broke the wicket-portlet?

I'll try to downgrade step by step. Until recently I didn't use wicket in
portal environment. All I know is that with wicket 1.5 (tested until 1.5.9)
my library was ok in Liferay 6.1. In the mean time I upgraded my library to
wicket 6 but it seems that was not a wise decision :) . I'll post my
conclusions later.

wicket portlet in Liferay 6.2

Hi,

I'm facing a problem with wicketstuff-portlet-6.16 in Liferay 6.2. I'm
using AjaxLink in a portlet and WicketAjax call failure with: Error while
parsing response: Invalid XML. I know there were some problems (starting
with wicket 1.5.9) but this problems were solved using a custom
IRequestCycleProvider. Can anybody help me with an answer if some
workaround is needed in wicketstuff-portlet 6.16?

Thank you

Re: inmethod grid cachedPageCount

2013-03-04 Thread Ciocoiu Elvis 
Thank you Paul,

But in my case I'm using IDataSource from immethod grid to retrieve the
current page. In client code after inserting the new record in the database
I'm obtaining the corresponding page number (greater than the one cached by
inmethod grid) and let the grid display itself (internally calls get page
from IDataSource). What I need is the easiest way to update the inmethod
grid to know that there is one more page). The most appropiate idea was to
set the current grid page to the last one but even if the grid let me do
that through its api (used also by the navigator) crashes because of this
internally cached page count. All the logic to retrieve the page based on
the current sort and filter is implemented. I don't want to change the
widget for the moment (inmethod grid is ok except this usecase) so I must
stick to IDataSource and it's usage.

multipart ajax upload

2013-02-24 Thread Ciocoiu Elvis 
Hi,

I'm fighting with a strange problem when using a form (multipart) with a
required TextField and a FileUploadField. Sometimes works as expected (the
required error message is displayed in FeedbackPanel) but most of the times
the feedback message is not displayed. Also, after submiting for a while
with empty text field I've got a message in Wicket Ajax Debug:

   1. Wicket.Ajax: Wicket.Ajax.Call.failure: Error while parsing response:
   Could not find root  element
   
wicket-ajax-debug-ver-1359989915360.js:91

  4. Wicket.Ajax.Call.loadedCallback
  
wicket-ajax-ver-1359989915360.js:1307
  5. Wicket.Ajax.Call.handleMultipartComplete


The main problem is when clicking multiple times the form onSubmit is
called (even if the text field has no value). It seems that
FeedbackMessages.hasError(...) returns false ...

Can somebody help me with this? I'm using wicket 1.5.9. The problem appear
without selecting a file in the FileUploadField. I just submit an empty
form multiple times.

Thank you.

inmethod grid cachedPageCount

2013-02-24 Thread Ciocoiu Elvis 
Hi,

I'm trying to select a item of inmethod grid after adding it in an ajax
call. Based on the current sort properties and filters, after I effectively
add the element in the database but in the same ajax call I'm determining
the element's page number and try to set it as current page in the grid. My
code works except in the case when the created element is in the last page
(the current grid page page count is cached internally in
AbstractPageableView.cachedPageCount). In this case the cachedPageCount is
equal to the create element page and when calling
grid.setCurrentPage(newPage) { ... if (page < 0 || page >= pageCount &&
pageCount > 0) ... } throws IndexOutOfBounds exception. I want to clear the
cachedPageCount somehow ... or maybe there is another solution? I want to
select the new page in the same ajax call. For the moment if I encounter
this situation I select the previous page ... but the my newly created
element is on the next one :(

Can somebody help me with some hints?

Thank you

Re: custom listeners

2012-05-17 Thread Ciocoiu Elvis 
EditorContext {
void registerPropertyProvider(PropertyProvider propertyProvider);

 PropertyAccessor createPropertyAccessor(String propertyName);
...
}
...


public class SomePanel extends LazyPanel {
 @BasicField(lookup = true)
private City city;
 @BasicField(lookup = true, showActions = true)
private List persons;
 @Override
protected void onCreate() {
EditorContext editorContext = new EditorContext();
 PropertyAccessor selectedCityAccessor =
editorContext.createPropertyAccessor("city");
 selectedCityAccessor.registerPropertyChangeListener(new
PropertyChangeListener() {
@Override
void onPropertyChanged(City oldValue, City newValue) {
// do something here, for example refresh the personsPanel ... or filter it
}
});
 Panel cityPanel = editorContext.createFieldPanel("city");
Panel personsPanel = editorContext.createFieldPanel("persons");
 add(cityPanel);
add(personsPanel);
}

}


The problem is that the personsPanel generates some links for CRUD
operations on personsList ... and creates panels for creating/updating the
selected person. The editorContext is shared between these fieldPanels and
can register listeners ... my question where is the proper place to
unregister them?

For the moment I try to minimize  this usage but it's not only the
listeners mechanism that I'm fighting with ... The framework let me
register configurers at runtime that also must be unregistered ... so I'm
trying to find some sort of a callback to clean whatever the component did
at creation time.

I'll adapt it to events in 1.5 but right now I'm closing the 1.4 chapter.

Re: custom listeners

2012-05-16 Thread Ciocoiu Elvis 
I'm working on a framework that builds the user interface (input fields,
labels, containers for layout, grids, ...) and one of the features is that
a custom field editor (for example a dropdown) can publish events (for
example value changed). Internally when creating the field editor I
register it it as a PropertyProvider somewhere ... in a shared
EditorContext. So this EditorContext is a central point in building a
particular form. One other fieldEditor can declare it's interest in events
of type valueCHanged published by the first field editor (the dropdown).
Well in EditorContext I have a map of propertyProviders and
PropertyChangeListeners ... But my framework generates also some links for
filtering and CRUD features ... and replaces dynamically the components
(for example the user click on add link and the list of persons is replaced
with a form that creates a new person). FInally every dynamically generated
form can have a field that listen for property change so I need a way to
unregister somewhere. Can I do it using the wicket component callbacks ...
like register the listener in onCreate and unregister it in onDestroy? (I
know that there is no onDestroy for component ... but maybe other
callbacks).


Thank you
