Ron,
So if I have a method that retrieves the values for a page property, is
it best to put this method in every get/set that requires the property
to be set, or to have it placed just once in prepareForRender?
Cheers
Dan

You don't have to override renderPage for that. Infact what you do is
setting the property after thew page was rendered... so its a bit too
late ;-)
What you should do is pass the list as a parameter, rather than as a
property. Then, in your page you do:
<span jwcid="myComponent" categories="categories"/>
in the class, you implement
public List getCategories() {
getComponent(...).get...
}
Cheers,

Hello there!
I have a page (Start.page) which has a List of categories objects.
This page has a component, with a nested component on it:
<span jwcid="@Border">
<span jwcid="groupPanel" blockNames="ognl:user.groupList">
<span jwcid="@CategoriesBorder"/>
</span>
</span>
User is also a property from my page. And the categoriesBorder:
<component-specification class="org.apache.tapestry.BaseComponent"
allow-body="yes" allow-informal-parameters="no">
<property-specification name="categories" type="java.util.List">
page.categories </property-specification>
</component-specification>
<span jwcid="@Foreach" source="ognl:categories" element="category">
<table border="0" bgcolor="#FFFFFF" cellpadding="0" cellspacing="0"
width="85%" align="center">
<tr>
<td jwcid="@Any" element="td"
bgcolor="ognl:category.color" width="30%">
<span jwcid="@Insert" value="ognl:category.title"/>
</td>
<td></td>
</tr>
<tr>
<td jwcid="@Any" element="td"
bgcolor="ognl:category.color" width="100%">
<table cellspacing="1" width="100%">
<tr>
<td bgcolor="#FFFFFF" width="100%"> </td>
</tr>
</table>
</td>
</tr>
</table>
<p><br>
</span>
Problem is, the categories is empty, null...
The page that contains the component (Start.page) has renderPage
overriden
public void renderPage(IMarkupWriter arg0, IRequestCycle arg1) {
super.renderPage(arg0, arg1);
TabPanel tabPanel = (TabPanel)getComponent("groupPanel");
Group group = (Group)tabPanel.getSelectedBlock();
setCategories(getUserService().getCategories(group));
}
I've debug it and the catetories have been set properly. Any ideas?
Thanks
