AbstractUsecase.getView() are called multiple times.
Hi all,
I noticed in a module I am currently developing that the getView() from
AbstractUsecase are called multiple times. I am not sure why but it
feels like a bug that it is called more then once.
I tried to debug and counted that the method is invoked 6 times. If you
start lenya in debug mode and set a breakpoint at line 666 (no kidding
the 'evil' line) in AbstractUsecase then you will note requesting
lenya.usecase=admin.usecases exactly this phenomenon.
The whole problem about it is that the first time all parameter are in
the request but after that not anymore.
My class is very simple:
public class ShowReports extends AbstractUsecase {
...
protected void prepareView() throws Exception {
...
}
}
Meaning I just want to override the prepareView() method.
My xconf looks like:
<xconf xpath="/cocoon/usecases"
unless="/cocoon/usecases/component-instance[@name =
'reporter.showReports']">
<component-instance name="reporter.showReports"
logger="lenya.reporter"
class="org.apache.lenya.modules.reporter.ShowReports">
<view uri="modules/reporter/usecases/showReports.jx" menu="true"
createContinuation="false">
<tab group="admin" name="reporter"/>
</view>
</component-instance>
</xconf>
Does anybody see the same problem?
Any ideas?

Request
http://localhost:8888/default/authoring/index.html?lenya.usecase=admin.usecases
and see that the breakpoint you added to line 666 in AbstractUsecase get
hit >=6 times. :(
Maybe it is because of cocoon?

First I was on trunk and then switched to the release tag. I am using
java 1.5 on a ubuntu box. I may find time this morning to test with
another box.
will let you know my findings.

I just placed a breakpoint in this line and tried it with a different
usecase, it was invoked 2 times:
* directly by the usecases.js
* when the UsecaseProxy is initialized
Do you use the trunk or 2.0.2?

the reason for this is that Usecase.getView() is called by the
MenuFilterTransformer because it needs the area information (which is
the tab group for the admin area).
I have now introduced a method Usecase.setupView().
AbstractUsecase.setupView() calls prepareView(). This way, it is only
called once, just before the view is presented to the user.
The change should be fully backwards compatible.
Would you mind doing an SVN update and trying it again?
TIA!
