I'm attempting to take the functionality contained in the ChartPage class from the Tapestry Workbench example and encapsulate it into a component instead of a page. (I'm using Tapestry 3.0.3.)
My ChartComponent defines a parameter "chartData" of type Vector that contains the data used to generate the chart. In the html template of the containing page, I pass in a Vector entitled "data" to the ChartComponent: <span jwcid="@ChartComponent" "chartData"="ognl:data"/> where "data" is a property of the enclosing page of type Vector. I have noticed that this strategy only works if the "data" property of the enclosing page is declared as persistent. Otherwise, by the time that my chart service tries to obtain the "data" vector from the enclosing page, that property is null. Why is that? Thanks so much, Howard --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
