Number as null

Maxim S — Fri, 02 Jun 2017 10:49:40 -0400

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?

add custom column into RTable

josef_koupal — Tue, 14 Jun 2016 17:02:16 -0400

Hello!

Is there a runtime possibility of creating a new column in designed ivy-RTable ? I have tried to do it with java in onLoad method of RichDialog - no success. Adding an empty column and setting header text is ok so far. I add a Custom implemented ITableCellRenderer and override the one and only method getTableCellRendererComponent(...)

Renderer of designed ivy table column is of type ch.ivyteam.ivy.richdialog.widgets.components.renderers.TableCellRenderer. This type if for me in designer not accessible. Using debugger i have seen the table model configuration String (>7000 chars) in it, but i can not edit it or create new one.

When i try to use my custom renderer for new column, e.g. com.ulcjava.base.application.table.DefaultTableCellRenderer or ULCLabel, i am never able to render the text in this column. I have tried multiple methods (setText(), setValue(), "value" parameter...) but cell is always rendered empty. the only thing i can set is background color.

Is there a way for such thing ?

Thanks in advance josef koupal

auto initialisation / number 0 from JSF View

tauser — Thu, 03 Mar 2016 08:44:40 -0500

Hello, we have a datatable in jsf view, one column is a number in bean. After submiting form (ivy event) we receive initialised number 0, so our validation cannot check if user inserted it manually (field is mandatory, 0 must be explicit inserted). How can we avoid the auto initialisation ?

Editable Datatable and Recordset

matej_smetana — Wed, 02 Mar 2016 13:35:37 -0500

Hi, I have a problem with p:datatable which has dynamic number of columns and it is editable. Data source of the table is ivy Recordset.

The problem is when a user change some value, this change is not processed into Recordset so the Recordset remains with old values. I have tried to change the datatable to use cell editor - with no effect.

Here is the code:

{lgi.prioritizationComposite.getRows()} returns a Recordset

Do you have any idea what is wrong? In HTML dialog demos there is an example of datatable and recordset. But I see nothing special in it.

Thanks Matej

How can I circumvent NullPointerException in data bindings?

Yves Jarczyk — Thu, 12 Jan 2012 11:22:39 -0500

I try to select an entry in a combo depending on a value in a record set like that:

panel.comboCountry.selectedIndex 
    <- Integer.parseInt(in.EmployeeList.getField(in.RowId,"country").toString())-1

This works properly, but if NULL is stored in the recordset, then Ivy throws a NullPointerException.

How can I circumvent this?
