Description

I was using a PieChart component based on the tips from the wiki (http://wiki.apache.org/tapestry/Tapestry5HowToCreatePieChartsInAPage) and when i switched to T5.0.9 i got this error:

1. org.apache.tapestry.ioc.internal.util.TapestryException
   java.lang.ClassNotFoundException: int[]

location
classpath:br/com/javasoftware/erp/pages/consultas/CstEstoque.tml, line 42, column 26
37 <br/><br/>
38 </center>
39 <center>
40 <t:piechart width="400" height="300"
41 labels="pieLabels" values="pieValues"
42 popup="popupSize" />
43 <table t:type="grid" source="resumoList" row="resumoItem"
44 remove="iduniq,datcad,conta_pc,tipoimposto" reorder="descri, total" >
45 <t:parameter name="totalCell" >
46 <span t:type="OutputLocale" value="resumoItem.total"
47 format="literal:currency" />

1. java.lang.ClassNotFoundException
   int[]

the popup parameter is an int[] parameter:

/** width and height of the popup chart, if omitted, javascript for popup chart is omitted from output*/
@Parameter
private int[] _popup;

and i defined it on my class like this:

public int[] getpopupSize(){
return new int[]

{800,600}

;
}

Is important to say that this component was functioning since the 5.0.5 version. This is the full stack trace:

An unexpected application exception has occurred.
