Table: ItemClickListener difference between 6.3.0 & 6.4.5 ?

Vaadin 6 / 7 / 8 Framework UI
1

Hi all,
This simple code was working without any error with 6.3.0.

this.tbl.addListener(new  ItemClickListener() {
     @Override
     public void itemClick(ItemClickEvent event) {
          Item item = event.getItem();
     }
});

but since i upgraded to 6.4.5 i have this error:

java.lang.ArrayIndexOutOfBoundsException: 8
	at com.vaadin.terminal.gwt.client.MouseEventDetails.deSerialize(MouseEventDetails.java:124)
	at com.vaadin.ui.Table.handleClickEvent(Table.java:2142)
	at com.vaadin.ui.Table.changeVariables(Table.java:1963)
	at com.vaadin.terminal.gwt.server.AbstractCommunicationManager.handleVariables(AbstractCommunicationManager.java:1094)

	at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269)
	at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188)
	etc...

I tried to use the ActionHandler on the table instead, in 6.4.5,but i never succeeded in having the handleAction method called, event with a simple code.

this.tbl.addActionHandler(new Action.Handler() {
     @Override
     public Action[] getActions(Object target, Object sender) {
          return new Action[]{new Action("Test")};
     }

     @Override
     public void handleAction(Action action, Object sender, Object target) {
          if ("Test".equals(action.getCaption())){
               //---
          }
     }
});

Any suggestions are welcome
Thx

Hi!

This looks, to me, like a regression. Could you please file a ticket for this at
dev.vaadin.com
?

Thanks,

Just to make sure, check that the widgetset you are using comes from the new Vaadin version - it is easy to forget to update or recompile it when upgrading Vaadin.

At least in the past, I have seen MouseEventDetails serialization errors caused by the wrong widgetset version.

Hi
I had updated and recomplied the widgetset but didn’t export it…:*)
Now it works great
Thanks for your answers.

I am getting the same error. I recompiled the widgetset in eclipse. Then i rebuilt my project. As I tried to deploy it, eclipe statet, that my widgetset might need a rebuid so I did it again. Still the error persists…
Please state, what I am missing.

[Edit: The debug messages tell me, that my widgetset has the wrong version. I have updated all Vaadin related plugins in eclipse, still the rebuild seems to produce only an outdated widgetset. Is this documentated anywhere? I am running in circles for about an hour now, just because I updated my vaadin version about a week ago and I have to rebuid widgetsets now, just becaus I want to click on an item in a table, which ist not properly done by the eclipse plugin (or I just do not know, how to to this the proper way). ]

This sounds like a caching problem. Try destroying all relevant cache folders from your application server, and doing a full reload in the browser (shift+reload) and clearing the browser cache as well.

Cleared my cache, removed the portlets from the web-inf dir, removed the temp directory…now it does not even deploy (stuck whent tomcat tells me, copying was done and deploymen will start in a few seconds). I am using liferay as a container. Maybe there is an issue with that? Still did not find any document regarding this. Is there somthing fundermental about updating my vaadin version i fail to understand?

Oh, OK, using Liferay. Not much of an expert on that area, but you might want to look at this add-on, which should help maintain your Liferay installation with Vaadin add-ons:
Vaadin Control Panel for Liferay

Hi,
Did you find a solution ? my initial problem was not on Liferay, but Tomcat. I had this twice. Once because my widgets was outside (another jar) my main app and i didn’t exported it, and the other one was because i have forgetten to update the vaadin.jar in the lib directory of Tomcat and restart it.
