Thanks ! Andreas
It works after I moved setUsers() in renderComponent to @InitialValue
annotation like this
@Persist
@InitialValue("Collections.EMPTY_LIST"
but table contents are getting displayed even without pressing search
button for the second time when I came back to the this page which has got
this table.
So Basically the data persistence should be lost once I move out of the page
which has the table component. For that I changed @Persist to
@Persist("page") but it doesn't look like page scope is present. I am
getting this error
[ +/- ] Exception: Exception invoking listener method search of component
phone/AddPhoneUser/searchForm: Error at Annotation
@org.apache.tapestry.annotations.Persist(value=page) of public abstract
java.util.List org.sipfoundry.sipxconfig.site.user.UserSearch.getUsers():
Unknown property persistence strategy
'page'.<https://scs2.asiapac.nortel.com:8443/sipxconfig/phone/AddPhoneUser,selectUserForm.sdirect#>
How to go about this ?
Thanks,
Seshu
