Got a few questions/queries (unrelated to each other) about TagLibs.
------
Firstly, are taglibs supposed to create a new instance of the corresponding
class for a tag each time a tag is encountered? A problem I'm having is
suppose I have a taglib which outputs 'Hello World' unless a NAME property
is set in which case it says hello to the name.
<test:hello />
<test:hello name="Joe" />
<test:hello name="Someone" />
<test:hello />
Output with Orion:
Hello World
Hello Joe
Hello Someone
Hello Someone <--- wrong (should say Hello World)
I can't figure out a way around this. Is there a method that is called when
a new instance of the tag is called (before the properties are set) so the
default value can be reset?
------
Secondly, I have a few taglibs which are used on most JSP pages I have. Is
there a way to automatically imply the <%@ taglib %> tag for all pages in a
web-application without having to use the tag at the top of each page?
------
Finally, I've used the EJB taglib that came with the demo news-app quite
extensively, but when I upgraded from 0.8.2 to 0.8.3, all my JSP pages only
outputted data until the first encounter of an <ejb:iterate> tag and then
just stopped.
The site.log shows this Exception:
java.lang.NoSuchMethodError
at com.evermind.ejb.taglib.IterateTag.doAfterBody(IterateTag.java:48)

I noticed that I'm not the only one having this problem. Can anyone shed
any light? I downloaded the full zip file containing 0.8.2, but then just
downloaded orion.jar to upgrade. Are there any other files I should have
included?
------
Thanks in advance.
