Hello guys, Brand new to cocoon, I have only been playing around with it
for about aweek, but already made quite some progress in getting up a small sample
app to get to know Cocoon.I am having a small problem with getting
action-sets towork though. I am
using Cocoon 2.1m2 on a Debian/testing box with standard 1.3 Blackdown
JDK.
Everything, including all samples work fine and the sample app that I am
writing works with mainly tries to do standard db stuff works as well if I
code it as show in the mod-db samples. When I try to take the actions out
of the pipeline and put it into an action-set as show in the action
documentation it fails with a NullPointerException when I try to do
anything. I have copied the stack trace below to not clutter up space
here.
This is the working code I have: <map:match pattern="iets">
<map:act type="req-params">
<map:parameter name="parameters" value="add-album Album.name
Album.parent_id"/> <map:act type="db-add">
<map:parameter name="table-set" value="Album"/>
</map:act>
</map:act>
<map:redirect-to uri="show_images"/>
</map:match> when I try to do something like this it fails:
<map:action-sets> <map:action-set name="album-add">
<map:act type="req-params">
<map:parameter name="parameters" value="add-album Album.name
Album.parent_id"/> <map:act type="db-add">
<map:parameter name="table-set" value="Album"/>
</map:act>
</map:act>
</map:action-set>
<map:action-set name="gallery-actions">
<map:act type="session-invalidator" action="logoff"/>
<map:act type="session-validator"/>
<map:act type="album-add" action="addAlbum"/>
</map:action-set>
</map:action-sets> <map:match pattern="iets">
<map:act set="gallery-actions"/>
<map:redirect-to uri="show_images"/>
</map:match> Now is there something I missed in the documentation? Is
it not possibleto nest parameters in an action within an action-set?
Thanks, Erwin Exception thrown: Original Exception:
