Beginner needs help with PageActivationContext and page navigation in Tapestry

2011-07-25 Thread Julien Martin 
Hello,

I have a page that lists job postings (beans) as follows:

Template:
*t:recruiters.recruiterslayout xmlns:t=
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd;
xmlns:p=tapestry:parameter
form t:type=form t:id=jobPostings
t:grid source=jobPostings row=jobPosting add=activate,modify
exclude=jobPostingValidationDate
p:activatecell
t:actionlink t:id=activate
context=jobPosting.idJobPostingactivate/t:actionlink
/p:activatecell
p:modifycell
t:actionlink t:id=modify
context=jobPosting.idJobPostingmodify/t:actionlink
/p:modifycell
 /t:grid
/form
/t:recruiters.recruiterslayout
*
Java:
*package com.cheetah.web.pages.recruiters;


import com.cheetah.domain.JobPosting;
import com.cheetah.service.CheetahService;
import org.apache.tapestry5.EventConstants;
import org.apache.tapestry5.annotations.OnEvent;
import org.apache.tapestry5.annotations.PageActivationContext;
import org.apache.tapestry5.annotations.Property;
import org.apache.tapestry5.ioc.annotations.Inject;


import java.util.Date;
import java.util.List;

public class JobPostingsTable {

@Property
private ListJobPosting jobPostings;

@PageActivationContext
@Property
private JobPosting jobPosting;

@Property
private Date date;

@Inject
private CheetahService service;

@OnEvent(EventConstants.ACTIVATE)
void loadJobPostings() {
jobPostings = service.loadJobPostings();
}

@OnEvent(EventConstants.ACTION)
void activateJobPosting() {

}

@OnEvent(value = EventConstants.ACTION, component = modify)
Object modifyJobPosting() {
   return ModifyJobPosting.class;
}
}*

However, when I click on the action link with t:id=modify, the job posting
id is lost... and the ModifyJobPosting page is not able to display the bean.

Template for ModifyJobPosting:
*t:recruiters.recruiterslayout xmlns:t=
http://tapestry.apache.org/schema/tapestry_5_1_0.xsd;
xmlns:p=tapestry:parameter
t:beandisplay object=jobPosting /
/t:recruiters.recruiterslayout*

java for ModifyJobPosting:
*public class ModifyJobPosting {

@PageActivationContext
@Property
private JobPosting jobPosting;

}*

I must be missing something obvious about PageActivationContext usage. Can
anyone please help?

Regards,

Julien.

Hi Julien,

to call your ModifyJobPosting page from JobPostingsTable page  use a page
link instead of an action link. The template would look like:
t:pagelink t:page=ModifyJobPosting
t:context=jobPostingsmodify/t:pagelink
This makes the method modifyJobPosting redundant.

Returning page's class in a handler method you tell Tapestry where to  
navigate to, but yor target page needs a context. Just create a Link  
with context and return it instead of class.

Me again, I have a typo in the pagelink (damn copy and paste). The value for
the context parameter must be jobPosting of course.

Thanks to both of you.

@NilleHammer: it works with the page link. Thanks.
@Igor: if I want to follow your suggestion, can I still use an actionLink or
do I need an Eventlink instead?

Actually, I am not sure how to to it you way Igor. Here is what I tried:
*
@OnEvent(value = EventConstants.ACTION, component = modify)
Object modifyJobPosting() {
   return componentResources.createEventLink(EventConstants.ACTION,
jobPosting);
}
*
*t:actionlink t:id=modify context=jobPosting.idJobPosting
modify2/t:actionlink*

However I know it does not make sense. Can you please help?

Julien.

I think something like this might do the trick. 

@Inject
 private LinkSource _linkSource;

Class? onActionFromModify(String contextId) {
   return linkSource.createPageRenderLinkWithContext(YourClass.class,
contextId);
}

Hi Julien

LinkSource is an internal serivce, you should use PageRenderLinkSource

http://tapestry.apache.org/current/apidocs/org/apache/tapestry5/services/PageRenderLinkSource.html#createPageRenderLinkWithContext(java.lang.Class,
java.lang.Object...)

regards
Taha

As Taha indicated, you probable should use PageRenderLinkSource  instead of
LinkSource. Good luck!
