Something you could try is adding a property called "formatType" in
your table bean. Implement the setFormatType method to create an instance
of the appropriate formatter and store it in the bean as another property
called "formatter".
Then, the graphics designer can use the following tags:
<usebean name="dynamicTable" type="com.mypackage.TableBean">
<setoncreate beanproperty="formatType" value="currency">
<setoncreate beanproperty="formatter.decimals" value="2">
</usebean>
I'm assuming that you can use sub-properties in the <setoncreate>
tag - I admit I haven't actually tried it. Anyone think of another
solution?
Cheers,
Greg.
