We’ve set up the following grid, which uses JSON and dynamic loading:
[code]
mygrid = new dhtmlXGridObject(“gridbox”);
mygrid.setImagePath("…/codebase/imgs/");
mygrid.setHeader(“DID,Author,To,CC,Subject,File Type”);
mygrid.attachHeader("#numeric_filter,#text_filter,#text_filter,#text_filter,#text_filter,#text_filter");
mygrid.setInitWidths(“100,110,130,130,300,70”);
mygrid.setColAlign(“left,left,left,left,left,center”);
mygrid.setColTypes(“ro,ro,ro,ro,ro,ro”);
mygrid.setColSorting(“int,str,str,str,str,str”);
mygrid.enablePaging(true,100,null,“pagingArea”,true);
mygrid.init();
mygrid.setPagingSkin(“bricks”);
mygrid.load("…/codebase/generateDocsJSON.jsp",“json”);
[/code]
The total_count value is set to 5000 records. Each request generates 1000 records.
When we attempt to enter a filter, we get a “’_locator’ is null or not an object” error. I have confirmed that all rows being generated have a unique ID value.
When we attempt to sort a column, we get a “‘this.rowsBuffer[…].idd’ is null or not an object” error.
If the total_count is set to 1000 records or the request is set to generate 5000 records (in other words; if we don’t use dynamic loading), then neither of these errors occur.
If we navigate enough to cause all 5 blocks of 1000 to load, then neither of these errors occur.
From the look of it, it seems like the dynamic loading aspect is preventing the filtering and sorting from being possible until such time as everything has been fully loaded into the grid. Is this supposed to be supported funcitonality? Or is this a known limitation?
Thanks!
