When attempting to use a 'db:select' tag in an empty
form (no table), and setting the fieldName attribute to
a unique name, a NullPointerException is thrown. From
the documentation and looking through the source code,
this seems to be allowed. Determined the exception was
being thrown in DbBaseHandlerTag in the method
'setFieldName'. Modified the method as such:
public void setFieldName(String fieldName)
{
this.fieldName = fieldName;
if (parentForm.getTable() != null) { // MGS
this.field =
parentForm.getTable().getFieldByName(fieldName);
}
else {
this.field = null;
}
if (parentForm.isSubForm())
{
// tell parent that _this_ class will
generate the html tag, not DbBodyTag!
if (this.field != null) // MGS
parentForm.strikeOut(this.field);
}
}
I'm currently using this fix and it seems to work well.

ps this was on our bug list but I doubted anyone would see it there.
