RE: [jmoney-devel] mortgage/loan plugin

[Nigel W. <ja...@mi...>]

Todd,

I have gone thru the steps to add the new account type, one at a time,
and seeing what JMoney does after each step with the following steps not
completed.  JMoney seemed to give a reasonably sensible error message in
most cases, tho it was not consistent in the messages.  Sometimes the
error appeared in the console, sometimes it appeared in one of the log
files.  I think that errors in plug-in configuration should be more
prominent, i.e. always shown in a message box to the user.

However, at the last moment I thought to try one more error case.  I
tried
setting the info-class attribute to a class that did not implement
IPropertySetInfo interface.  This indeed resulted in no message
appearing and the account not being listed, so is almost certainly your
problem.

The offending line is 221 of PropertySet.java.  The code, which I wrote,
simply ignores the extension if the interface is not implemented.  I
have now corrected this to generate an error message.

I have also checked in some changes to field.exsd, as attributes such as
info-class had not been set to 'required'.

Hi,

So I've got my plugin working with the JMoney app--the Loan Account
dummy prefs show up as a page in the Preferences.  But.  I can't get
my plugin to show up in the popup list of new accounts.  I'm extending
net.sf.jmoney.fields:

   <extension
         point="net.sf.jmoney.fields">
      <extendable-property-set
            base-property-set="net.sf.jmoney.currencyAccount"
            id="loanAccount"
            info-class="org.suppressingfire.chambery.LoanAccountInfo"/>
   </extension>

but when I step through NavigationView.makeActions():

		for (Iterator iter =
CapitalAccountInfo.getPropertySet().getDerivedPropertySetIterator();
iter.hasNext(); ) {
			final PropertySet derivedPropertySet =
(PropertySet)iter.next();

LoanAccount is not among the derived property sets (only BankAccount).
 I only have the bare amount of code in place to run, essentially
copied from BankAccount.

Am I missing something obvious to include the LoanAccount with other
CapitalAccounts?

Thanks,

Todd
