> ClassCastException in HeaderCell.addToTotal when totaling column
> ----------------------------------------------------------------
>
> Key: DISPL-375
> URL: http://jira.codehaus.org/browse/DISPL-375
> Project: DisplayTag
> Type: Bug
> Components: Tag Library
> Versions: 1.1
> Reporter: Michael Watts
> Fix For: 1.1.1
>
>
> I am getting a ClassCastException in
> org.displaytag.model.HeaderCell.addToTotal when value for cell is the empty
> string "". This is a problem when totaling a column using the total="true"
> attribute on ColumnTag.
> This method should be changed to avoid this problem. Here is my proposed:
> Original:
> =====
> private void addToTotal(Object value)
> {
> if (value != null)
> {
> this.total = this.total + ((Number) value).doubleValue();
> }
> }
> =====
> Proposal:
> =====
> private void addToTotal(Object value)
> {
> if (value != null && value instanceof Number)
> {
> this.total = this.total + ((Number) value).doubleValue();
> }
> }
> =====
