portlet-selector.vm [INFO: Velocity [warn] Warning!] Message
Hi All
I have implement portlet selector and put into my application.
Code for "user-portlet-selector.vm" is enclosed below.
All related files are used psml,PortletSelector.java, velocity jar files etc...
When user click on "select" link to pop up the portlet selector window, warning message is displayed at log file. Portlet selector is working fine only problem is throwing warning message at log file.
INFO: Velocity [info] ResourceManager : found /WEB-INF/view/selectors/user-portlet-selector.vm with loader org.apache.velocity.tools.view.servlet.WebappLoader
Aug 19, 2005 12:06:42 PM org.apache.catalina.core.ApplicationContext log
INFO: Velocity [warn] Warning! The iterative is an Iterator in the #foreach() loop at [0,0] in template /WEB-INF/view/selectors/user-portlet-selector.vm. Because it's not resetable, if used in more than once, this may lead to unexpected results.
How to handle this warning message?
This portlet selector displays only those portlets that does not contained in the page. When user click on "select" button we refresh the portlet by submiting the following form
<form name="refreshForm" action="$renderResponse.createActionURL()" method="post" >
<input type='hidden' name='db.browser.action' value='refresh'/>
</form>
Thanks in advance....
Regards
Rakesh

Easy answer: turn off warning level in velocity logging.
It appears they also log a warning whenever an iterator is used in
#foreach loop. Have a look at the code:
