This is just a wild guess:
In "page.components.holdingQuantityPie.size"
getPage().getComponents() is a map. How should you be able to retrieve
a component out of that?
couldn't you try something like
page.getComponent(holdingQuantityPie).size?
I am not 100% sure about the ognl syntax...

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
