> Key: TAPESTRY-1193
> URL: https://issues.apache.org/jira/browse/TAPESTRY-1193
> Project: Tapestry
> Issue Type: Bug
> Components: Framework
> Affects Versions: 4.0.2
> Reporter: Jim Steinberger
> Assignee: Jesse Kuhnert
> Priority: Minor
> Fix For: 4.1.2
>
>
> In .script files, the "index" value of the "foreach" tag is stored as a
> String, not an integer.
> If you have a two-dimensional array stored in the input-symbol "matrix", the
> following will work fine:
> ${matrix[0].length}
> But the following, where "matrixIndex" is the symbol used for a surrounding
> "foreach"-tag's "index" value, will throw an error:
> ${matrix[matrixIndex].length}
> The error will tell you that "matrix" does not have the property: 0.
> i.e. since matrixIndex is a String, it's looking for a property of the
> array-object named "0".
> This issue doesn't arise with comparisons, such as ${matrixIndex > 0},
> because OGNL knows to interpret matrixIndex as an integer. However, again,
> in the case of indexes to [ ], both an integer and String parameter are
> acceptable, so no implicit casting is done on the String.
> A workaround: [EMAIL PROTECTED]@parseInt(matrixIndex)].length}
