Hi,
You've got to remember that the operations you're doing have to make logval
sense in a Java environment when doing comparisons - particularly string
comparisons.
Try this.......
#if( $!var.equalsIgnoreCase("string1") && !$!url )
<a href="$url"><img src="image1"></a>
#elseif( $!var.equalsIgnoreCase("Yes") && !$!url )
<a href="$url"><img src="image2"></a>
#elseif( $!var.equalsIgnoreCase("No") && !$!url )
<a href="$url"><img src="image3"></a>
#elseif( !$!url )
<a href="$url"><img src="image4"></a>
#else
<!-- nothing -->
#end
You should also be careful about comparing strings to "" when you may well
mean null.

How would I state the following correctly in Velocity?
#if( $!var == "string1" && $!url != "" )
<a href="$url"><img src="image1"></a>
#elseif( $!var == "Yes" && $!url != "" )
<a href="$url"><img src="image2"></a>
#elseif( $!var == "No" && $!url != "" )
<a href="$url"><img src="image3"></a>
#elseif( $!url != "" )
<a href="$url"><img src="image4"></a>
#else
<!-- nothing -->
#end
When I execute this code with var equal to "string1" and url not equal to
"", I expect it to execute the 1st block.
However, it executes the 4th block instead.
Any ideas what I may be doing wrong?
Thanks.
