Re: Trouble updating component after async. directlink : clientId's generated in For-loops

2006-11-22 Thread Kim Thrysøe 

Thank you for the response. That is exactly what I wanted.

But ... something is still odd. I get too and mixed up updates back to 
in the ajax-response requests. Is this a bug or expected behaviour?


_Click on first row :_
Tapestry / DojoAjaxResponseBuilder sends
* response id=therow type=element  (actually containing both first 
and second row(!)

* response id=initializationscript type=script
Works fine.

_Click on second row :_
* response id=Insert type=element
* response id=therow_0 type=element
* response id=DirectLink type=element ie. of first row
* response id=initializationscript type=script
DOJO warns: WARNING: 10:06:53 AM: No node could be found to update 
content in with id Insert


_Click on third row :_
response id=Insert_1 type=element
* response id=DirectLink_0 type=element
* response id=initializationscript type=script
DOJO warns: WARNING: 10:05:40 AM: No node could be found to update 
content in with id Insert_1

Can I suggest that we get this into the docs in some way.  It stumps a
lot of people, including myself.



http://issues.apache.org/jira/browse/TAPESTRY-1137 proposes a binding
for that
exact use-case, i.e. updateComponents=clientId:therow


  

Also, it seems like if I want to
update a component by calling ResponseBuilder.updateComponent() from
within a listener method, I have to give it the id of the component,
rather than the clientId.  In that case, does it only update the
current instance of the component accessed by that id, or will it
update every component that uses that id as the code iterates over a
collection in some way? If it is the former, how would I update the
row that follows the current row?  Is it even possible?

Trouble updating component after async. directlink : clientId's generated in For-loops

2006-11-21 Thread Kim Thrysøe 
In a page containing elements generated by a component placed under a 
For-Loop component I want to be able to update a single such 
component/element using the very nifty 
DojoAjaxResponseBuilder.updateComponent()  feature.


In summary I want to have a DirectLink for each row in a table. The 
listener method for this DirectLink will update data, the row should be 
updated via the updateComponents attribute of DirectLink.


But... how do I address components generated (and thus named) by a 
For-loop?

updateComponents=therow will work for first row
updateComponents=therow_2 does not work at all (sends updates to the 
Insert and DirectLink components in stead!

updateComponents=ognl:'therow_' + theIndex  has the same behaviour. .

Hopefully this small example illustrates my issue: one column for data 
one for the async DirectLink to listener aListener. This code works 
for the _first_ row but not the other two.


*The html*
div jwcid=@Shell title=Test
div jwcid=@Body class=templatewide

   table border=1 cellpadding=5
  
   span jwcid=@For source=ognl:rows value=ognl:row 
index=ognl:theIndex

   tr jwcid=[EMAIL PROTECTED]
   td
   span jwcid=@Insert value=ognl:row /span
   /td
   td
   a jwcid=@DirectLink
   listener=listener:aListener
   async=true
   parameters=ognl:{theIndex}
   updateComponents=rowid
   Update this row!
   /a
   /td
   /tr
   /span
  
   /table


   /div
/div

*The Page Class*
import org.apache.tapestry.IRequestCycle;
import org.apache.tapestry.annotations.Persist;
import org.apache.tapestry.event.PageEvent;

import dk.atira.tapestry.AbstractBasePage;

public abstract class NumericPage extends AbstractBasePage {

   @Persist
   public abstract String[] getRows();
   public abstract void setRows(String[] rows);
  
   public abstract String getRow();

   public abstract int getTheIndex();
  
   @Override

   public void pageBeginRender(PageEvent e)
   {
   if (getRows() == null){
   setRows(new String[] {foo, bar, baz});
   }
   }
  
   public void aListener(IRequestCycle cycle, int idx)

   {
   getRows()[idx] =  + (int)(Math.random()*1);
   }
  
}


/thanks
