Hello All,
I am checking Grid With Local Paging demo in GWT-Ext showcase, It has 10
records and its paging size is 5, when i select 2 from one page and goto
next button and select 3 in second page, when i come back in first page all
the selection is removed
My all code is:
private static BaseColumnConfig[] mergeBaseColumnConfig(BaseColumnConfig[]
baseColumnConfigs, BaseColumnConfig rowNumberingColumnConfig,
BaseColumnConfig checkboxColumnConfig) {
int baseColumnConfigsLength = baseColumnConfigs == null ? 0 :
baseColumnConfigs.length;
int baseConfigsLength = baseColumnConfigsLength;
baseColumnConfigsLength = checkboxColumnConfig != null ?
baseColumnConfigsLength + 1 : baseColumnConfigsLength;
baseColumnConfigsLength = rowNumberingColumnConfig != null ?
baseColumnConfigsLength + 1 : baseColumnConfigsLength;
BaseColumnConfig[] mergeBaseColumnConfigs = new
BaseColumnConfig[baseColumnConfigsLength];
int j = 0;
if (rowNumberingColumnConfig != null) {
mergeBaseColumnConfigs[j] = rowNumberingColumnConfig;
j++;
}
if (checkboxColumnConfig != null) {
mergeBaseColumnConfigs[j] = checkboxColumnConfig;
j++;
}
for (int i = 0; i < baseConfigsLength; i++) {
int index = i + j;
mergeBaseColumnConfigs[index] = baseColumnConfigs[i];
}
return mergeBaseColumnConfigs;
}
public void onModuleLoad1() {
Panel panel = new Panel();
panel.setBorder(false);
panel.setPaddings(15);
PagingMemoryProxy proxy = new PagingMemoryProxy(getCompanyData());

StringFieldDef("company"), new FloatFieldDef("price"), new
FloatFieldDef("change"), new FloatFieldDef("pctChange"), new
DateFieldDef("lastChanged", "n/j h:ia"), new StringFieldDef("symbol"), new
StringFieldDef("industry") });
ArrayReader reader = new ArrayReader(recordDef);
final Store store = new Store(proxy, reader, true);
ColumnConfig[] columns = new ColumnConfig[] { new
