OGNL Indexing issue after migration to JBoss 7

Question

I am currently migrating a legacy system using Struts2/OGNL from JBoss 6.1 to JBoss 7.4 where an issue with object indexing with OGNL is occurring.

The following function is causing expression setting error in JBoss 7.4 which doesn't occur in the older version:

public Object getRowData(int index) {
    while(index>=rows.size()){
        try {
            addRow(recordClass.newInstance(), false);
        } catch (Exception e) {
            logger.error("Error Grid getRowData",e);
            e.printStackTrace();
        }
    }
    return rows.get(index).getValue();
}

which when called by OGNL in JBoss 7 is throwing similar errors such as the one below:

[com.opensymphony.xwork2.ognl.OgnlValueStack] (default task-1) Error setting expression 'form.internalCodeGrid.rowData[7].createBy' with value '[Ljava.lang.String;@454e1cae': ognl.NoSuchPropertyException: com.cnt.tdc.tag.grid.Grid.rowData

where basically OGNL is failing to get the indexed element. This issue does not occur in JBoss 6.1.

I can replicate the exact same issue, down to the same issue log errors, in JBoss 6.1 by renaming/removing the getRowData() function.

Any help would be appreciated.

JARs and property files used:

• struts2-core-2.3.15.1
• ognl-3.0.6
• struts.xml (identical)

Alright, managed to fix it by adding the function below in the same class.

public Object[] getRowData() { return new Object[0]; }

I'm assuming that this fixes the problem because JBoss 7.1 handles JavaBeans than 6.4 and required more stringent pattern compliance.
