Hi,
I have a List of objects, lets say: List<Column>
A column object looks like this :
Column -Integer id
-String name
- List<String> values
The generated excel file should look like this:
id1 id2 ...... etc
name1 name2 ......
val11 val21
val12 val22
val13
The template looks like this:
<jx:forEach items="${cols}" var="col"> ${col.id} </jx:forEach>
<jx:forEach items="${cols}" var="col"> ${col.name} </jx:forEach>
<jx:forEach items="${cols}" var="col"> <jx:forEach items="${col.values}"
var="val"> </jx:forEach>
${val}
</jx:forEach>
When trying to generate the excel using this template I get an error:
java.lang.RuntimeException: items property in forEach tag must be a
collection. col.products is not
The same template only with the first two line works just fine.
Any idea why this happens?
Best regards,
Deina------------------------------------------------------------------------------
