Vaadin REFRESH

Junior Member Bejegyzések: 49 Csatlakozás dátuma: 2011.03.06. Legújabb bejegyzések
Hi All,
I started to switch from alloy to vaadin.

But i have got a trouble with Vaadin Form. I will tell an easy way.
I have two portlet. In first portlet, I populate a select component from database. it is working properly.
In second portlet, I get new data from user for first portlet's select component. But cannot repopulate the first portlet in current user session.

How can I refresh the first portlet's window?

Use the Liferay IPC plugin to send messages between your portlets.

You could send the data collected in portlet 2 to the listener on portlet 1, or you could send a simple message indicating that portlet 1 should refresh itself...

Alternatively you could use the Refresher plugin in portlet 1. It will invoke a method on portlet 1 to allow you to refresh automatically on a timed basis.

Thanks David,
I used the Liferay IPC. It is working if portlets are on the same page.
When i put separate pages, first portlet is not refreshing.

I think instead of 'Liferay IPC plugin' that David meant to write 'Vaadin IPC' plugin ? (https://vaadin.com/directory#addon/vaadin-ipc-for-liferay)

Vaadin IPC plugin uses Javascript so, yeah same page only

In contrast, and more generically Liferay IPC can do send/receive between portlets when placed on different pages ; Rick Sezov's "Liferay in Action" gives some detail on this I think

can you show me any example for Liferay IPC. is it working with vaadin?

Also I am searching a method like onload instead of init method.
so, if a user refresh the page, the window should be refresh too. because it is possible that another user can change this portlet's data.
Is there any a simple way for this issue?

I like Rich Sezov's Liferay in Action book example for Liferay IPC (inter-portlet communication). I think there is at least one wiki on this too somewhere here at www.liferay.com.

I've used Vaadin IPC Plugin and I've used Liferay IPC with MVCPortlet but haven't tried Liferay IPC with Vaadin.

I can't tell if you are asking about refreshing only the Vaadin portlet or the entire browser window. There are ways for each.

Yes portlet events work with Vaadin. Here's a link for a basic implementation: http://demo.vaadin.com/6.2.0.pre1/docs/example-source/com/vaadin/demo/portlet/

Even though it says 6.2.0.pre1, the concepts are basically the same for all of Vaadin 6. May change under Vaadin 7, but since it's not out yet who knows?

Thank you David,
As i mention above, is there any other simple method to refresh the page?
Because A lot of function can impact the current page's data, so it does not make sense to use IPC for every transaction.

For that I'd use the refresher plugin.

It calls a method in your registered listener to refresh content.

Yeah, that's the right plugin but the Vaadin class that you end up using is LiferayIPC emoticon
