-------------------------------------------
> Velocity Template with HTTPRequest object
> -----------------------------------------
>
> Key: VELOCITY-181
> URL: https://issues.apache.org/jira/browse/VELOCITY-181
> Project: Velocity
> Issue Type: Bug
> Components: Build
> Affects Versions: 1.3
> Environment: Operating System: All
> Platform: PC
> Reporter: Sushma
> Assigned To: Velocity-Dev List
>
> Hi,
> I am having a problem with velocity.
> I am using:
> 1. Tomcat version 4.1.18
> 2. velocity-dep-1.3.jar
> 3. Java1.4.0( build 1.4.0-b92)
> 4. Windows 2000.
> I am using velocity template with servlets.
> Problem Description:
> 1.Whenever one of the parameters for a method is HTTPRequest object in the
> velocity template the
> link does not get translated.
> 2.If the method has only HTTPRequest object as the parameter it works.
> 3.But HTTPRequest in combination with other parameters does not seem to work.
> For Example:
> Following DO NOT WORK:
> <h2> <a href="$link.getBrowseURL($request, "A", 1, 15)">REQ + String + Int =
> NOT WORKING</a></h2>
> <h2> <a href="$link.getBrowseURL( "A", 1, 15,$request)">String + Int + REQ =
> NOT WORKING</a></h2>
> <h2> <a href="$link.getBrowseURL( $request,1, 15)">REQ + Integer = NOT
> WORKING</a> </h2>
> Following WORK:
> <h2> <a href="$link.getBrowseURL("A", 1, 15)">String + Int = Working</a> </h2>
> <h2> <a href="$link.getBrowseURL( 1, 15)">Only Integer = WORKING </a> </h2>
> <h2> <a href="$link.getBrowseURL( $request)">Only REQ = WORKING</a> </h2>
> IS this a BUG or mistake on my part.ANY suggestions are welcome.
> THANK YOU

> Following is the code for velocity and servlet.
