I ran into the same crash, but in my case it's not reproduceable all the time!

Hello,

We are having a crash there :

CXTPReportColumn* CXTPReportColumns::Find(int nItemIndex) const
{
        for (int nColumn = 0; nColumn < GetCount(); nColumn++)
        {
                CXTPReportColumn* pColumn = GetAt(nColumn);
                if (pColumn->GetItemIndex() == nItemIndex)
                        return pColumn;
        }
        return NULL;
}

We are having a case where the method GetAt(...) returns NULL, and the variable pColumn is NULL. You access directly to a member method of that variable without checking for its validity.

Our temporary workaround is to code our own Find method.

Please fix that for the next release, as we use the Find in many other parts of the code.

Thank you.
