RPB repeaterBlock tag (WLP8.1) with WLP9.2 -
"Expressions in a dataSource must bind to a single property."
Hi !
I need to use the repeaterBlock (the taglib included in rpb.jar that was
written for 8.1) in 9.2. (details of 8.1 usage are at
http://dev2dev.bea.com/lpt/a/38 ).
When I'm running my below implementation I receive the following error
message:
The expression "pageContext.packs" is an invalid expression for a
dataSource. Expressions in a dataSource must bind to a single property.
although what I did is the same with the example I found. I had to
import in WEB-INF\lib rpb.jar and netui-scoping.jar (these are 8.1
libraries).
I'm wondering if this taglib that used xscript (
dataSource="{pageContext.packs}" ) under 8.1 is able to cope with the
new
9.2 style (without curly braces).
I'm using the following code:
