-----------------------------------------
> issue with simple math operations in template
> ---------------------------------------------
>
> Key: VELOCITY-8
> URL: https://issues.apache.org/jira/browse/VELOCITY-8
> Project: Velocity
> Issue Type: Bug
> Components: Engine
> Affects Versions: 1.1-rc2
> Environment: Operating System: All
> Platform: PC
> Reporter: Andriy Rozeluk
> Assigned To: Velocity-Dev List
>
> Trying to add up a total amount for prices or such things within a template
> isn't working -- looks like the context variable is resetting itself. I'm
> using
> the latest sources from 1.2-dev (20010621)
> Examples (two variations of the same thing, chopped out of my source code):
> #set( $totalPrice = 0 )
> #set( $items = ${bundle.getItems()} )
> #foreach( $i in $items )
> #set( $totalPrice = $totalPrice + $i.getPrice() )
> #end
> <!-- ${totalPrice} -->
> ##Example 2:
> #set( $items = ${bundle.getItems()} )
> #foreach( $i in $items )
> #if( $totalPrice )
> #set( $totalPrice = $i.getPrice() + $totalPrice )
> #else
> #set( $totalPrice = $i.getPrice() )
> #end
> <!-- ${totalPrice} -->
> #end
> Assume the items in question being looped through (yes, they are displaying
> properly) all have a price of $7, and there are 4 of them. The price is
> returned from a Java object which has a public double getPrice() method
> defined.
> The first example returns:
> <!-- -->
> <!-- -->
> <!-- -->
> <!-- -->
> The second example returns:
> <!-- 7.0 -->
> <!-- 7.0 -->
> <!-- 7.0 -->
> <!-- 7.0 -->
> Obviously, what I wanted was:
> <!-- 7.0 -->
> <!-- 14.0 -->
> <!-- 21.0 -->
> <!-- 28.0 -->
> My velocity.properties:
> resource.loader.1.resource.path = e:\\path\\to\\templates
> file.resource.loader.path = e:\\path\\to\\templates
> file.resource.loader.modificationCheckInterval = 30
> file.resource.loader.cache = true
> velocimacro.permissions.allow.inline = true
> velocimacro.permissions.allow.inline.local.scope = true
> velocimacro.context.localscope = false
> parser.pool.size = 20
> My system is Windows NT 4 running JDK1.3 and I'm using this with Tomcat 3.2.1
> Please don't hesitate to contact me if you need a better example (or help
> reproducing this problem). Obviously I got the 2 examples because I created
> the
> second in an attempt to work around the first one. Thanks for your help!
