Hello Igor,
Thank you for the reply, What I've implemented so far is I've converted the
hashmap keys and values to their respective collection types. but when I
pass either one of them to the grid component it displays the number of
objects passed but none of the information is passed. below is the code that
i have written for the display page.
So say for example i wanted to display just the keys i would pass the
issueKeys collection to the grid component correct? but it just displays as
aforementioned, an empty grid header with a false value in each row.
Side note:
this gird is being populated based on set of selections made on a grid that
was displayed on a previous page. I've debugged the information flow and i
can see the the HashMap is passed to this page and I see that the enclosed
ArrayList has information as well, its just Im not sure if perhaps the
information is getting lost at some point during the display of this grid?
Or maybe the accessor object that the component uses? Honestly I'm at a loss
as to what is going on...
public class Contact
{
@ApplicationState
private jiraDataSource jDO;
private HashMap String, ArrayListIssue issuesList;
private CollectionArrayListIssue issuesSet;
private CollectionString issueKeys;
private String issueKey;
private Issue issue;
void onActivate()
{
issuesList =jDO.getAllIssuesLists();
}
public void setIssuesList(HashMap String, ArrayListIssue issuesList)
{
this.issuesList = issuesList;
}
public HashMap String, ArrayListIssue getIssuesList()
{
return issuesList;
}
public Collection String getIssueKeys()
{
issueKeys = issuesList.keySet();
return issueKeys;
}
public CollectionArrayListIssue getIssuesSet()
{
issuesSet = issuesList.values();
return issuesSet;
}
public String getIssueKey()
{
return issueKey;
}
public Issue getIssue()
{
return issue;
}
public void setIssue(Issue i)
{
this.issue = i;
}
}
this is the page class its coming from:
public class About
{
@ApplicationState
private jiraDataSource jiraDO;
private Filter filter;
@InjectPage
private Contact contact;
public List Filter getAllFilters()
{
return jiraDO.getAllFilters();
}
public Filter getFilter()
{
return filter;
}
public void setFilter(Filter f)
{
this.filter = f;
}
@OnEvent(value=checkbox)
void CheckboxClick()
{
System.out.println(a Checkbox was clicked);
}
@OnEvent(value=submit)
Object tromSubmit()
{
System.out.println(submission made);
HashMap String, ArrayListIssue issuesList =
jiraDO.getAllIssuesLists();
contact.setIssuesList(issuesList);
return contact;
}
}

Just convert your Map into a GridDataSource which you pass to the
component.
Take a look at Tapestry's internal implementation of GridDataSource which
is
constructed from a collection.
http://tapestry.formos.com/nightly/tapestry5/apidocs/src-html/org/apache/tapestry5/internal/grid/CollectionGridDataSource.html#line.29
You can also provide a type coercion from a Map to GridDataSource or to
Collection. Tapestry will do the coercion for you.

Hello all,
I am once again stuck and unsure as to how to implement the following. I
have a HashMap that contains a String id for the Key and an ArrayList as
the
value. What I need to do is to display in a table or grid each arrayList
as
it corresponds to a Key.
How would you go about iterating first through the the id and implement
it
as a table header for example, then iterate through its corresponding
ArrayList? Basically nesting the loops... Sort or like generating a table
for each entry in the HashMap. Or if it could be implemented in one table
that should be fine as well.
Any help would be greatly appreciated.
Thanks,
Carlo
