Yes, it's null...
Do a
<span jwcid="@Insert" value="ognl:page.components"/>
to see which components are there...
Do you add these 2 components into the page directly?
or do you add a Border component into your page and then add those 2
components into the Border...
page.components only returns components directly added to the page
There's a getNestedComponent(String path) to get a nested component, i.e.
getNestedComponent("myBorder.holdingQuantityPie")
It should work...

I get no output from the insert at all - so it's null?

From the Exception thrown, it seems that
ognl: page.components.holdingQuantityPie
returns null, but I can't figure why, since your code seems correct.
Can you confirm this? i.e. instead of HoldingChart, add a
<span jwcid="@Insert" value="ognl:page.components.holdingQuantityPie"/>

Hi all,
I'm somewhat new to tapestry so apologies if this is obvious:
I have a squisher component which hides and shows its body. The squisher
has zoom buttons that adjust a member property called size:
<property-specification name="size" type="int" initial-value="200"
persistent="yes"/>
I want to be able to pass the size property to a subcomponent so that
can
affect the way it renders. This is what I have tried:
<div jwcid=*"[EMAIL PROTECTED]"* title="Holding Quantities
Chart">
<span jwcid=*"@HoldingChart"* user="ognl:page.visit.user" chartType=
"holdingQuantityPie" title="Holding quantities" size="ognl:
page.components.holdingQuantityPie.size"/>
</div>
Which gives the error:
org.apache.tapestry.BindingException Unable to resolve expression '
page.components.holdingQuantityPie.size' for
[EMAIL PROTECTED] binding:
ExpressionBinding[Home
page.components.holdingQuantityPie.size] location:
context:/WEB-INF/Border.html,
line 68
ognl.OgnlException source is null for getProperty(null, "size")
Can anyone tell me the correct way to do this?
(Using Tapestry 3.03)
Thanks,
Paul
