Mounting dynamic resources , wicket 1.5

2014-08-06 Thread Jayakrishnan R

Hi All,

I am trying out the Mounting dynamic resources as explained in  the
following article.

http://wicketinaction.com/2011/07/wicket-1-5-mounting-resources/

in the App.java , I have the following.
 mountResource(/images/${imgName}, new ImageResourceReference());

The image resource class is exactly the same.

I can see that a nice URL  is getting generated. But getting the following
exception on the page and the URL not working.

Hi Martin,

Thank you for the suggestions. I will check that.

I also have a question on securing such mounted resources when there is a
valid session. Is there a way to secure access to resources mounted like
this ?

I want such images to be accessible only for valid users when signed on.

Strict date pattern for DateTextField in Wicket

2013-07-03 Thread Jayakrishnan R

Hi All,

I have a DateTextField component in my application and I want the input of
date using a predefined pattern. The pattern that I need is -MM-dd. I
created the DateTextField using the following code.

DateTextField dtf_ExpiryDate =
DateTextField.forDatePattern(ExpDate, -MM-dd);
dtf_ExpiryDate.add(new DatePicker());

It helps to prevent date input in most of other formats. But it accepts
input in dd-MM- format and converts it into some weird format. For
example, *12-06-2013* is automatically converted to *0012-06-20*.

Is there a way to throw an error when the date is given in dd-MM- ?

Javadocs of 
DateTextFieldhttp://wicket.apache.org/apidocs/1.4/org/apache/wicket/datetime/markup/html/form/DateTextField.htmlsays
that the conversion is done internally using the Joda time parser. Is
there a way to add more constraints ?

I really don't want the data to be captured as String and add a
StringValidator to check if it confirms to the pattern using Regex.

Thank you

Re: Wicket DefaultDataTable - Refresh it on browser back button

2013-03-27 Thread Jayakrishnan R

Hi Martin,

Thanks for the direction. I finally found the problem. The list of records
( collection ) was assigned to the data provider in the contructor of that
page. So when I press back button, the latest data was not getting
refreshed.

I still need to find a way to push the latest data on to the model.

Thanks
JK

 Hi,

 Does that mean that the DataProvider returns primary key objects which are

 I am not sure. But one thing I noticed, the load() method of the
 LoadableDetachableModel is not being called when the back button is hit.

 I am getting exception the populateItem method .of the columns in the data
 table... see below.


 ListIColumnRecord columns = new ArrayListIColumnRecord();

 Check why your DataProvider returns (the ids of) deleted objects when back
 button is used.


 
  I used it to display a set of records ( say RecordList page). When I
 add or
  remove some records and load the page RecordList again, it displays the
  changes. However, if I use the back button of the browser and go the
  RecordList page which was rentered earlier ( before adding/ removing the
  records ). The *DefaultDataTable *still has the old sets of records.
 This
  is a big issue when records are deleted.
 
  For example, If I delete a record and press back button then the page
 fails

 Adding
  does not create an issue because it simply does not get listed in the

  In another page, I just have *PageableListView *with *

  Can someone advice me on how to refresh the data table on browser back

Re: Wicket DefaultDataTable - Refresh it on browser back button

2013-03-25 Thread Jayakrishnan R

Hi,
Does that mean that the DataProvider returns primary key objects which are
used in the LoadableDetachableModel to load the real object ?

I am not sure. But one thing I noticed, the load() method of the
LoadableDetachableModel is not being called when the back button is hit.

I am getting exception the populateItem method .of the columns in the data
table... see below.


ListIColumnRecord columns = new ArrayListIColumnRecord();

   columns.add(new AbstractColumnRecord(
new StringResourceModel(Record_number, this, null),
Record_number) {

@Override
public void populateItem(Item item, String id, IModel rowModel)
{
}};

  Hi All,

 Check why your DataProvider returns (the ids of) deleted objects when back
 button is used.


 
  I used it to display a set of records ( say RecordList page). When I add
 or
  remove some records and load the page RecordList again, it displays the
  changes. However, if I use the back button of the browser and go the
  RecordList page which was rentered earlier ( before adding/ removing the
  records ). The *DefaultDataTable *still has the old sets of records. This
  is a big issue when records are deleted.
 
  For example, If I delete a record and press back button then the page
 fails
  as the record it is trying to show does not exist in the database. Adding
  does not create an issue because it simply does not get listed in the set
  of records.
 
  In another page, I just have *PageableListView *with *
  LoadableDetachableModel*. It works fine with out an issue.
 
  Can someone advice me on how to refresh the data table on browser back
  button ?

Wicket LoadableDetachableModel exception handling issue

2013-02-20 Thread Jayakrishnan R

In my project, I am using LoadableDetachableModel as given below.

public ReportPage(final Objectm, final PageReference pr) throws
CustomException{try{final LoadableDetachableModelListMaintReport
ldm =
 new LoadableDetachableModelListMaintReport() {

@Override
protected ListMaintReportload() {
**// Some Database operations //**
return x;
}
};
/*
Several LoadableDetachableModels, PageableListViews, Panels, Fragments  etc.
*/ } catch ( Exception ex){// create Custom Exception } finally {
 // Clean up of stuff }


My problem is that I am using AbstractColumn to display the objects in the
column and the overriden populateItem() method calls the load()
internally.  Since both the methods cannot throw Exceptions, I cannot
really catch exceptions and display appropriate messages.

Any help on this is really appreciated.

i have already done that as a back up plan.  Do you think wicket is a bit
wierd in handling exceptions.

 How about wrapping it to a RuntimeException, or preferably, your own
 subclass of it?
