Hallo liebe gemeinde,
ich hab ein recht kurioses problem mit der wunderbaren Expression Language ;)
ich schieb mir ein Objekt als attribut in meinen request. (die klasse der variable pageConfig ist unten nochmal komplett)
request.setAttribute("currentPage", pageConfig);class PageConfig:
public class PageConfig {
private String name;
private String uri;
private Collection portletIds;
private int orderNumber;
public PageConfig() {
this.portletIds = new ArrayList();
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getUri() {
return uri;
}
public void setUri(String uri) {
this.uri = uri;
}
public Collection getPortletIds() {
return portletIds;
}
public void setPortletIds(Collection ids) {
this.portletIds = ids;
}
public void addPortlet(String contextPath, String portletName) {
synchronized(portletIds) {
portletIds.add(PortletWindowConfig.createPortletId(contextPath, portletName, createPlacementId()));
}
}
public void removePortlet(String portletId) {
portletIds.remove(portletId);
}
void setOrderNumber(int number) {
this.orderNumber = number;
}
int getOrderNumber() {
return orderNumber;
}
private String createPlacementId() {
return getName().hashCode() + "|"+portletIds.size();
}
}wenn ich nun in meiner jsp seite mit
<c:forEach var="portlet" varStatus="status" items="${currentPage.portletIds}">
<c:set var="portlet" value="${portlet}" scope="request"/>
<c:out value="${portlet}" />
</c:forEach>die collection im objekt durchlaufen will wird mir jedesmal eine Exception geworfen.

das objekt ist auch in jedem falle befüllt, da mir folgende testausgaben etwas liefern.
<%@taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
Length of ArrayList is ${fn:length(currentPage.portletIds)}
${currentPage.name}und das ergebnis kommt bei den "testausgaben"
Length of ArrayList is 2
About Apache PlutoIch weiß einfach nicht weiter, ich hoffe einer von euch kann mir ne zündende idee liefern.
Ich verwende übrigens Apache Pluto als Portlet Container, das sollte zwar keine Rolle spielen da es anscheinend eher ein Prob mir der Collection gibt, aber sicher is sicher, vielleicht hats ja doch was mit dem Container zu tun ;)
ich hab ein recht kurioses problem mit der wunderbaren Expression Language ;)
ich schieb mir ein Objekt als attribut in meinen request. (die klasse der variable pageConfig ist unten nochmal komplett)
request.setAttribute("currentPage", pageConfig);class PageConfig:
public class PageConfig {
private String name;
private String uri;
private Collection portletIds;
private int orderNumber;
public PageConfig() {
this.portletIds = new ArrayList();
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getUri() {
return uri;
}
public void setUri(String uri) {
this.uri = uri;
}
public Collection getPortletIds() {
return portletIds;
}
public void setPortletIds(Collection ids) {
this.portletIds = ids;
}
public void addPortlet(String contextPath, String portletName) {
synchronized(portletIds) {
portletIds.add(PortletWindowConfig.createPortletId(contextPath, portletName, createPlacementId()));
}
}
public void removePortlet(String portletId) {
portletIds.remove(portletId);
}
void setOrderNumber(int number) {
this.orderNumber = number;
}
int getOrderNumber() {
return orderNumber;
}
private String createPlacementId() {
return getName().hashCode() + "|"+portletIds.size();
}
}wenn ich nun in meiner jsp seite mit
<c:forEach var="portlet" varStatus="status" items="${currentPage.portletIds}">
<c:set var="portlet" value="${portlet}" scope="request"/>
<c:out value="${portlet}" />
</c:forEach>die collection im objekt durchlaufen will wird mir jedesmal eine Exception geworfen.
