I am also getting exceptions when I try to invoke action methods. I actually reproduced the docs example of print.println('Hello World!')
However, when I go invoke an action method with parameters, it craps out. Any idea of what could cause this, because the documentation says I can do the following syntax:
| <s:link value="Cancel" action="#{hotelBooking.cancel()}"/>
|
I changed the getStatus() to status and it works, I was just using that as an example previously, but here is what I really want to get working:
Purchase.java
| ...
| @Transient
| public Double totalUnitCost() {
| double total = 0;
| for(Item item : items) {
| total += item.getUnitCost();
| }
| return total;
| }
| ...
|
viewPurchases.xhtml
| ...
| <!-- Total Unit Cost-->
| <h:column>
| <f:facet name="header">
| <h:outputText value="Total Unit Cost" />
| </f:facet>
| <h:outputText value="#{purchase.totalUnitCost()}" />
| </h:column>
| ...
