Following is my usecase,
I am trying to manually set the data as recordList from server to the Listgrid via following code.
I will be calling fetchData for every 3 seconds. If the data contains exception then the above code will not be executed and be ignored else it will be executed.
Initially 0-75 records are loaded into the cache.
when i scroll beyond 75,
1.When scroll past the 75th records the request is made for
75-150 records are loaded into cache .
but before that the current cache is invalidated by the resultset.(you can see the bold log statement)
2.Also one more issue is the 150 records from server are cached at the position 0 always. I want the new records (75-150) to be cached /inserted at 75th position.
Logs:
Request :
First 0-75 invalid data (ignored)
0-75 call now for valid data

Code:

resultset.setInitialLength(response.getTotalRows());

Record[] initialData = new Record[response.getEndRow()+1];
for (int i = 0; i <= response.getEndRow() ; i++) {
GWT.log("i = "+i+" StartRow = "+response.getStartRow());
if (i < response.getStartRow()){
Record record = new Record();
record.setAttribute("id", Random.nextInt());
record.setAttribute("name", "Name"+Random.nextInt());
initialData[i] = record; //doing this for testing if i scroll past to // arbitary some records are filled for the rows above
//is there any solution for this ??
}else{ if(i- response.getStartRow() < responseData.length)
initialData[i] = responseData[i- response.getStartRow()];
}
}
resultset.setInitialData(initialData);
grid.setData(resultset);Initially 0-75 records are loaded into the cache.
