Hi Jake,
I have a custom table tag that needs Value Stack access, too.
Here's how I do it:
package...
import org.apache.struts2.views.jsp.TagUtils;
import org.apache.struts2.util.MakeIterator;
public class TableTag extends SimpleTagSupport
{
private String list;
public void doTag() throws JspException
{
ValueStack stack = TagUtils.getStack((PageContext)getJspContext());
Iterator iterator = MakeIterator.convert(stack.findValue(list));
while (iterator.hasNext())
{
...
}
}
public void setList(String list)
{
this.list = list;
}
}
Of course "list" is one of my custom tag's attributes and appropriately
defined in my TLD.
Cheers,
Bill
