    <p>I am using ExtJS 3.3.1 with Grails 2.0 to do pagination on screen, but it does not work as I expect. I followed the tip posted here: <a href="https://stackoverflow.com/questions/4548892/grails-extjs-grid-paging">Grails extJS grid paging</a><br> JS page </p> <pre><code>paramNames: {start:'offset',limit:'max',sort:'sort',dir:'order'}, baseParams: {offset:0,max:10}, </code></pre> <p>The pagingToolbar: </p> <pre><code>this.gridBBar = new Ext.PagingToolbar({ pageSize : 10, store : this.gridStore, displayInfo : true, displayMsg : 'Hiển thị {0} - {1} mục tìm được của {2} kết quả', emptyMsg : 'Không tìm thấy dữ liệu', }); </code></pre> <p>Controller: </p> <pre><code>def result = Floor.createCriteria().list( max:params.int('max')?:100, offset:params.int('offset')?:0 ) render ([count:result.totalCount,data:result] as JSON) </code></pre> <p>but the paging button (Next) was disabled because the store just contained only 10 item, no more to retrieve.<br> When I change the offset to 10: </p> <pre><code>paramNames: {start:'offset',limit:'max',sort:'sort',dir:'order'}, baseParams: {offset:10,max:10}, </code></pre> <p>the pagination is work well, except one strange thing: the grid always display the next 10 results (10th-20th record for 1st click, 20th-30th record for 2nd), not the current first 10 results. I don't know what the correct usage of pagination combined from ExtJs and Grails is. If you have experience in this problem, could you please share me some information?<br> Thank you so much.</p>

    2. COThe returned JSON is {"count":10, "items":[{"id":1, "name" : "AA"}, {"id":2, "name" : "B"}]}. I see that the statement render ([count:result.totalCount,data:result] as JSON) is not correct because the return list does not have the getTotalCount() method or totalCount property

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
