nested foreach problem

[wong wayne]

Dear groups

Sorry for last incomplete email. 

I have some problem when using nested foreach problem.
I have a list of products. It works fine when display
one by one using foreach. 

<component id="_foreach_product" type="Foreach">
  <binding name="source" expression="productList"/>
  <binding name="value" expression="product"/>
</component> 

<component id="_foreach_productPairs" type="Foreach">
  <binding name="source"
expression="getProductListPairs()"/>
  <binding name="value"
expression="getProductList()"/>
</component>

But when I try to group two of product into pair for
display, problem appear and error resulted.

"Unable to enhance class com.hket.myloop.page.Home
because it implements a non-abstract write method for
property 'productPairs'."

Can somebody give me some hints for this? Thanks.

coding fragment as attached

regards

wayne
