Tacos tree and java.Lang.ArrayStoreException help needed
Hi
My environment is Tomcat 5.5 + Jre 1.5 + T4 beta12 + tacos library alpa 6.
I'm in the middle of migration process from T3 to T4 and this is the
problem I can't solve on my own.
I use tacos tree to display category tree. I implement
ITreeContentProvider etc. When I display tree structure with only root
in it (trees of height 1) everything seems fine but when I try to
display trees higher than that i get exception that comes from tacos
library:
java.lang.ArrayStoreException
Stack Trace:
java.lang.System.arraycopy(Native Method)
java.util.ArrayList.toArray(Unknown Source)
net.sf.tacos.ajax.components.AjaxDirectLink.getLink(AjaxDirectLink.java:67)
org.apache.tapestry.link.DefaultLinkRenderer.constructURL(DefaultLinkRenderer.java:112)
org.apache.tapestry.link.DefaultLinkRenderer.renderLink(DefaultLinkRenderer.java:62)
org.apache.tapestry.link.AbstractLinkComponent.renderComponent(AbstractLinkComponent.java:95) org.apache.tapestry.AbstractComponent.render(AbstractComponent.java:617)
org.apache.tapestry.AbstractComponent.renderBody(AbstractComponent.java:434)
org.apache.tapestry.components.IfBean.renderComponent(IfBean.java:86)
$IfBean_8.renderComponent($IfBean_8.java)--
I identified code in Tacos source code which causes exception to be
thrown but can not say why:
public ILink getLink(IRequestCycle cycle) {
//Normal DirectLink listener parameters
Object[] params = constructServiceParameters(getParameters());
//Component id's to update
String[] updateComponents = new String[0];
if (getUpdateComponents() != null)
// here is the line that couses the exception to be thrown later
->(AjaxDirectLink line:67)
updateComponents = (String[])getUpdateComponents()
.toArray(new String[getUpdateComponents().size()]);
(...)
}
Please help me out guys
Thanks
