Re: How to Create a Remote Paging Listview Using GWT-Ext

Hi Rajesh,

Is the "total" attribute returned in your JSON correct? (the total field in the example I give is "totalPerons" - although that's a mis-spelling, it should be "totalPersons"). This attribute should be the total number of records in the listview, not just the current page.

Unfortunately i put all the getters and setters methods. Do you have another idea about this problem? Maybe i am doing a mistake and i didn't notice.

I notice the following:

JSONArray jsonPersons = new JSONArray(persons, true);

I don't have the constructor method JSONArray with a parameter boolean like you code. In my code is:

JSONArray jsonAccounts= new JSONArray(accounts);

Other observation:

How is inserted the attribute class in JSON:

{
"class": "class com._17od.servlets.Person",
"dateOfBirth": "2001-05-19",
"firstname": "Rebecca",
"id": 5,
"lastname": "Taylor"
}

Thanks a lot

Could it be that your Account object isn't a javabean (with getters for each attribute)?

Hi, very good code.

I just have one doubt. I follow the steps and my json is like it:

{
"accounts": [
com.microcpd.mapp.server.Account@13b9fae,
com.microcpd.mapp.server.Account@1706da8,
com.microcpd.mapp.server.Account@2f356f],
"totalCounts": 3}

Why are not showing the attributes of the Account, it's showing the object.

Thanks a lot

Fair point Melinda. I've included the name of the product and fixed the link.

Dude,

All very well and all, but next time, do you think you could actually provide the details of this "little gem" or at least ensure that your link takes you to a site where you can download it?

Great piece of codes to work with.I'm getting everything but the data being displayed too. The data is returned to the client and is nicely displayed in Firebug, but no sign of it in the GridPanel. Will this not change with new platforms enforced?

Hi,
Thank you for the great tutorial. I do need some help and guidance for the following issue -- The code works perfectly fine when run in hosted mode, however when I run it in web mode, I do not see any data in the grid. I do not get any exceptions either. I tried all possible ways/options and couldn't proceed further. Can you please guide me. Thanks a lot.

many many thanx for your hint. this is fantastic. no more Session closed! Exceptions. I will never follow the advices from the Hibernate Tutorial. With Adrian's hint you get maximum control over your transactions.
Thanx a lot Adrian

Hi Adrian,
Thanks for the nice article. I'm trying out something like this. I have a search criteria and when I click the submit button I need to load the store. I can see on the server side, the data is being generated and response is sent. But on the client side, the grid is not getting refreshed. I've posted the problem with code snippets here http://gwt-ext.com/forum/viewtopic.php?f=2&...

If possible, do let me know if you sense any problem somewhere.

regards
Prakash

Great howto. I found it extremely useful, since RPC serialization would just explode for > 700 of the entities I am working with.

Hi myio,

It's difficult to say what the best approach is without understanding your data and how it would be best presented. With 7000 rows of data I'd say you're on the right track with remote paging.

The Grouping Grid looks pretty similar to the standard Grid. From looking at the example here (http://www.gwt-ext.com/demo/#gridGrouping) the only difference is that you use a GroupingStore, a GroupingView and call grid.setAutoExpandColumn() on the GridPanel.

Re: How to Create a Remote Paging Listview Using GWT-Ext

myio — Wed, 13 Aug 2008 16:26:22 -0000

Thanks for the great tutorial. I want to use the Grouping Grid in my application. My data set is pretty large (around 7000 rows). This amount of data seems to be way too much to transmit/display all at once. I was trying to think of how I could use the model you have demonstrated with the tree-like functionality of the Grouping view. It seems like I have to split the work into at least two pieces: collecting and presenting data for the initial collapsed tree; and secondly collecting and presenting the data as each node in the tree is expanded.

Is there a better way? Can you recommend an approach? Is this even possible since the root/first level of the tree looks different from a data perspective (i.e. fewer columns than an expanded node showing record details).

Any advice would be appreciated.

ROS runs on a SUN Microsystems server, so it seems daft that it doesn't support Linux...

Hi,

I've been using UPM for a year now. And after my upgrading to Leopard, it stopped working. I've already installed JCE, but it not fixed the problem.

Can you help me? Please? I really need to access my data on the UPM database.

Sorry for bad english.

Thanks very much for the pointer to WifiDocs/Driver/Ndiswrapper. You were right, it is easy. I installed the WMP54Gv4.1 driver on Mythbuntu 7.10, and it seems to be working.
