I'm trying to get the CeWolf taglib to work with WW/Velocity. However, findAncestorWithClass() fails with a null response. Does the #bodytag-directive support this and/or am I doing something wrong?
Here's my template:
$req.setAttribute("dataset", $dataset)
#bodytag(SimpleChart "id=line" "title='Test'" "type='line'" "xaxislabel='X'" "yaxislabel='Y'" )
#bodytag( Data )
#tag( Producer "id=dataset")
#end
#end
The ProducerTag fails with a NullPointerException at de.laures.cewolf.taglib.tags.ProducerTag.doEndTag(ProducerTag.java:57) due to the line
DataAware dw = (DataAware) findAncestorWithClass(this, DataAware.class);
returning null.
Any ideas?
Yep. It looks like tag.setParent wasn't being called. I've fixed the stuff in CVS. Give it a whirl now :)
Cheers!
