hi!
i'm playing around a bit to implement my suggestions for a new
workflow menu. i figured the easiest thing to start with would be a
per-user "notify submitter" preference.
i read ChangeVisiblity.java and copied it's structure. in
pubs/default/config/menus/generic.xsp i added
<menu i18n:attr="name" name="Workflow">
<block>
...
</block>
<block>
<item
uc:usecase="site.changeNotification"><xsp:expr>notificationChar</xsp:expr><i18n:text>Notify
submitter</i18n:text></item>
</block>
</menu>
and declared a dummy notificationChar that is always "x" for a start.
then i created a file
src/java/org/apache/lenya/cms/site/usecases/ChangeNotification.java.
Just a note - that should go into the notification module.
ok. so i create
src/modules/notification/java/src/org/apache/lenya/cms/site/usecases/ChangeNotification.java
?
does that path make sense? or should it rather be in
src/modules/notification/java/src/org/apache/lenya/notification ?
when i do "./build.sh --noconfig" it seems to be built along with the
rest. it does nothing so far but implements the same methods as
ChangeVisibility.
now when i restart lenya and look at the workflow menu, the new option
appears to be grayed out. do i need to register this new usecase
somewhere?
Yes, use a patch file
modules/notification/config/cocoon-xconf/usecase-changeNotification.xconf
i tried that, and it does not change anything. still grayed out. my
patchfile says:
[EMAIL PROTECTED]:/local/lenya-build/lenya_1_4_X/src/modules/notification/config/cocoon-xconf>
cat usecase-site-changeNotification.xconf
<?xml version="1.0"?>
<xconf xpath="/cocoon/usecases"
unless="/cocoon/usecases/[EMAIL PROTECTED] =
'site.changeNotification']">
<component-instance name="site.changeNotification"
logger="lenya.site"
class="org.apache.lenya.cms.site.usecases.ChangeNotification"/>
</xconf>
and the (dummy) implementation is
[EMAIL PROTECTED]:/local/lenya-build/lenya_1_4_X/src/modules/notification>
cat java/src/org/apache/lenya/cms/site/usecases/ChangeNotification.java

thanks for those pointers.
anyway, that's a little out of scope for now. how should i proceed to
add a per-user two-state setting for notification? modify the user
interface and everything above? or is there a more idiomatic way to do
it?
Actually I'd just add the information to the session for the moment.
sounds reasonable.
