Number as null

Dear Ivy Team.

We faced with the autounboxing problem. On UI side we have input field for number:
<pe:inputNumber value=#{data.num}/>
or <p:inputText value=#{data.num}>

On data model, the field 'num' has type Number. When a user saves data, then we get value 0 in this field. Can we store null value?

We read question:
http://answers.axonivy.com/questions/1674/auto-initialisation-number-0-from-jsf-view

We tried set COERCE_TO_ZERO=false in: \AxonIvyDesigner6.5.0.53277\webapps\ivy\WEB-INF\web.xml

<context-param>
<param-name>org.apache.el.parser.COERCE_TO_ZERO</param-name>
<param-value>false</param-value>
</context-param>

in %JAVA_OPTS%: -Dorg.apache.el.parser.COERCE_TO_ZERO=false
in process code, as: System.setProperty("org.apache.el.parser.COERCE_TO_ZERO", Boolean.FALSE.toString());

But it didn't help for us.
Could you correct us, what do we need do any more for Designer and then for Engine?

Where do we need set variable ivy.vm.additional.options?

ErrorHandler for "Dialog instance is not available anymore"

Dear Ivy Team.

Is it possible to catch error "Dialog instance is not available any more" via ErrorHandler process?

I made ErrorHandler the similar as in example ErrorHandlingDemos with error code: "ivy:error". But it's not working. We would like to move user to home page when that error happens. We use SVN for a project in workspace and we wouldn't want to change web.xml in the designer (for example to replace error page) because it is beyond SVN.

Thanks!
