Adding an entry to the underlying observable list of a table view does not get added to the table view

I found a couple of things which are better than JavaFX when multiple views are opened which share the same observable list:
1. In JavaFX update of a cell in one tableview does not lead to an update in other views. (raised as RT-21142 in JavaFX Jira)
In case of GroovyFX I can make it work with the following workaround: By creating a button, setting it as userData for table and in onEditCommit of column calling the fire method on the button before updating the underlying property. In JavaFX, this workaround does not work, thing that works is adding a blank entry to table or resetting items of all table views.
2. In JavaFX if one of the views is sorted by certain sort order, all the existing views are sorted by the same order. In GroovyFX all the views maintain their individual sort order.

Arvinder,

You don't see the new items in the table because the TableView demo does not use binding. To make the table automatically update, you must first make the persons list into an ObservableList and create a Property for it:

ObservableList<Person> persons = FXCollections.observableArrayList([
    new Person(name: "Jim Clarke", age: 29, gender: Gender.MALE, dob: new Date() - 90),
    new Person(name: "Dean Iverson", age: 30, gender: Gender.MALE, dob: new Date() - 45),
    new Person(name: "Angelina Jolie", age: 36, gender: Gender.FEMALE, dob: new Date())
])

final personsProperty = new SimpleObjectProperty(persons)

Then you simply use the bind statement in your tableView node:

tableView(items: bind(personsProperty), ...) {

Once this is done you should observe the same behavior as with regular JavaFX.

Dean,
Thanks for answering my question.
I tried it out but by doing so I am not seeing anything in the table view. I have attached a sample script, TableViewDemo2.groovy
Another question I have is that why this behavior is different from JavaFX. In JavaFX, I do not need to wrap my observableList with an object property.
Arvinder

Dean,
When I tried the solution suggested by you above in my own project, it worked! I verified that now the added items are being shown correctly, but wrt sorting the table views based on a single observable list, GroovyFX also started exhibiting the same behavior as JavaFX (#2 in my first comment above). It looks like I need an observable list per table view to make sorting work in multiple tables.

Regarding TableViewSample not working, To see if an older version was causing it not to work, I updated the GroovyFX project and now when I try to run any demo I get the error below.
Please let me know If it is a bug

Can the above exception be due to the fact that I am using 2.1 developer build(from about 2 months ago) and not 2.1 GA?

Are you using GroovyFX 0.1 (master branch) or 0.2 (develop branch)?

I am using the develop branch

Arvinder,

I was able to run your TableDemo2 code just fine on the latest version of GroovyFX and JavaFX 2.1 GA. I did have to add an import statement:

import javafx.collections.ObservableList

Without the import, Groovy will interpret it as a groovy.util.ObservableList.

Dean

Dean,
The import was the missing part. Now it works. But I would still like it to work the same as JavaFX so that I do not have to wrap the list in an object property.
