[jboss-user] [JBoss Seam] - Re: Argh! Attribute access

For anyone else that runs into this problem - it occurs because it is not permitted to call a method of a List implementation - you can only access its index. The following example will fail with the error mentioned previously. E.g. SummingList.java | public class SummingList extends ArrayList<Integer> { | ... | public Long getSum() { | Long sum = 0L ; | for (Integer value : this) { | if (value != null) { | sum += value ; | } | } | return sum ; | } | ... | } | SummingList.xhtml | ... | <h:outputText value ="#{summingList.sum}" /> | ... | The workaround is to move the extra functionality to outside the list, e.g. | public class SummingList { | | public void setList(List<Integer> list) {...} | public List<Integer> getList() {...} | | public Long getSum() {...} | | } | This looks like a facelets bug/ strange implementation choice to me: LegacyELContext.java extract: | /* Line 137*/ if((base instanceof List) || base.getClass().isArray()) | /* Line 138*/ return getPropertyResolver().getValue(base, Integer.parseInt(property.toString())); | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024664#...
