[jira] Updated: (VELOCITY-146) Macros not evaluated on the first attempt
[ http://issues.apache.org/jira/browse/VELOCITY-146?page=all ]
Will Glass-Husain updated VELOCITY-146:
---------------------------------------
Bugzilla Id: (was: 17669)
Fix Version: 1.5
(was: 1.4)
Description:
I have noticed that sometimes macros do not get evaluated after Velocity has
just been started. A subsequent request for the same resource produces a valid
document, where macros are now correctly evaluated.
Here's an example: I have a WAP-Mail webapp, which runs on Tomcat 3.3a. It uses
Velocity to render the content, and the Velocity versions I have used are 1.2-
dep, 1.3-dep and 1.3.1-dep. This problem occurs with all of these versions.
The first request should produce a message list (there's an autologin feature,
so the message list page is the first one being accessed). Here's the most
relevant part of the content:
------------------------------------------------------------------------------
<p>Folder: INBOX<br/></p>
<p>
<br/><b>Date: 05.03 11:16</b>

For some reason, #newMessageButton and #logoutButton -macros do not get
evaluated when the first request is processed. Friends of mine have also
reported similar behaviour in their applications.
Is there some kind of "lazy initialization" in macro processing or is this a
bug?

Thanks for reporting this. We're going through old bugs - we'll resolve this before 1.5 release.
