String comparison
Hi,
I know this has probably been asked a million times, but I can't seem to
find a straight answer in the docs or mailing list archives. I am having
trouble getting String comparison working in my Velocity templates.
Here is some sample code I have for generating a select box with the
correct option selected:
-------------------------
#set ($selected = $author.AuthorType)
#if (!$selected)
#set ($selected = "S")
#end
<select name="author_type">
<option value="S"#if ($selected.equals("S")) selected="1"#end>Student</option>
<option value="T"#if ($selected.equals("T")) selected="1"#end>Teacher</option>
<option value="O"#if ($selected.equals("O")) selected="1"#end>Other</option>
</select>
--------------------------
I have also tried using:
#if ($selected == "S") selected="1"#end
But that doesn't seem to work either. I have inserted html comments
into my template containing $selected, and it always prints out
correctly, but the code above still doesn't work.
Any help would be greatly appreciated.
Thanks,
-- Rodney

Sorry for the late reply... I've been busy on other stuff.
$author.AuthorType should call author.getAuthorType() which returns a
java.lang.String.
Thanks for your help,

WYSIWYG editors
Posted by Shawn Church <sh...@boxity.com>.
I have always for the most part hand-coded html (including .vm and .wm
templates), but I am wondering if there is a quicker alternative. I'm
through much of the Java coding for my most recent project, and I am just
beginning the trudge through the presentation layer.
Any opinions for or against a particular WYSIWYG editor is appreciated, and
of course it must at least tolerate the presence of embedded VTL.

It's faster. I run cached.

No, not yet.

Turning caching on
Posted by Darren Evenson <DE...@safenetconsulting.com>.
Should I have anything to fear by turning caching on in production? Are
there any known issues where Velocity's behavior (output) is different based
on whether caching is turned on or off? I'm actually achieving acceptable
performance without caching, but faster is always better.
I'm using Velocity within my app to format email messages. Unfortunately,
for now, I'm locked into another templating language for my web pages :-)
BTW, is there any way to take advantage of caching when the template comes
from a String, rather than a file?
Thanks,

What does $author.AuthorType return?
