Depends on where you added the addActionError() call, at the very
least--an action error indicates a validation problem, so it may be
trying to go to the "input" result.
Not enough information to help.
It seems that I may get my answer soon!
More info comes:
=========================
(1) Action1.java
public class Action1 extends ActionSupport
{ .. ....
public String execute() throws Exception
{
HttpServletRequest req = ServletActionContext.getRequest();
HttpServletResponse res = ServletActionContext.getResponse();
/* paging method for display tag */
process_paging(req);
return SUCCESS;
} ...
}
(2) Action1 in struts.xml
<action name="*Action1" method="{1}" class="Action1">
<result name="success" type="tiles">browse_action1</result>
</action>
(3) tiles for browse_action1
<definition name= "browse_action1" template="t.jsp">
<put-attribute name="body" value="browse_action1.jsp" />
</definition>
(4) browse_action1.jsp
... ...
<s:form id="Action1Form"
name="Action1Form"
action="Action1"
validate="true"
theme="simple">
<display:table id="row_rec"
name="alist_paging_bean"
export="true"
class="simple"
cellspacing="0"
cellpadding="5"
requestURI="Action1"
keepStatus="true"
pagesize="<%=bean_display.getPageSize() %>"
partialList="true"
size="<%=bean_display.getTotalRecNum() %>"
sort="external"
>
<display:column property="c1" title="c1" sortName="c1" sortable="true"/>
... ...
</display:table>
<s:submit value="Update" theme="simple" action="update_guiAction2">
</s:submit>
</s:form>
(5) Action2.java
public class ProcessThesis extends ActionSupport
{
public String update_gui() throws Exception
{
HttpServletRequest req = ServletActionContext.getRequest();
HttpServletResponse res = ServletActionContext.getResponse();
String[] error_arr = new String[2];
String[] checkbox_value =req.getParameterValues("checkbox_value");
if(Utils.isEmpty(checkbox_value))
{
addActionError(this.getText("at.least.one.rec.error"));
return "view_action1"; //Step_Q1 -> "Page not found()404"
}
return "view_action1" ; //Step_Q2 -> no error at all
}
}
If remove "addActionError(this.getText("at.least.one.rec.error"))",
return successfully! Otherwise, "Page not found 404"returned!
(6) struts.xml for Action2
<action name="*Action2" method="{1}" class="Action2">
<result name="view_action1" type="redirectAction">
<param name="actionName">Action1</param>
</result>
</action>
I tried also the following, but it does not work either:
<action name="*Action2" method="{1}" class="Action2">
<result name="view_action1" type="tiles">browse_action1</result>
</action>
Thanks a lot!

Hello,
addActionError() caused "Page not found (404)" Error.
(1) Action1.java
browsing all records using displaytag
(2) Action2.java
if just say:
return "view"; go to Action1 successfully
if:
addActionError(...); //then
return "view";
Got an "Page not found (404)" exception.
Does anyone know what cause the problem?
Thanks a lot!
