Hi Isomorphic,
I have a problem that started to happen after the release of v12.0p_2019-10-30/PowerEdition Deployment (built 2019-10-30) - it's not happening in 2019-10-29!.
Button is not recreated after update. Method "updateRecordComponent" is not called at all.
Unfortunately I was unable to reproduce this problem in built-in-ds.
But my code looks like:
Bug doesn't appear in two cases:
-If I remove "setGroupValueFunction"
-If button is visible to all records
I hope you have enough information to detect the problem.
Best regards
Pavo
I have a problem that started to happen after the release of v12.0p_2019-10-30/PowerEdition Deployment (built 2019-10-30) - it's not happening in 2019-10-29!.
Button is not recreated after update. Method "updateRecordComponent" is not called at all.
Unfortunately I was unable to reproduce this problem in built-in-ds.
But my code looks like:
Code:
package com.smartgwt.sample.client;
import com.smartgwt.client.types.GroupStartOpen;

@Override
public void onRecordDoubleClick(RecordDoubleClickEvent event) {
// Open window
// Update datasource "yyyy". That update changes some values of "supplyItem"
// Update response to datasource "yyyy" is returned and it contains related update to "supplyItem".
}
});
ListGridField itemNameLGF = new ListGridFieldGroupBy("itemName");
ListGridField categoryLGF = new ListGridFieldGroupBy(categoryGroupByField);
// Many fields....
setFields(itemNameLGF, categoryLGF);
}
@Override

return "gray";
else
return super.getCellCSSText(record, rowNum, colNum);
}
@Override

return updateRecordComponent(record, colNum, null, true);
}
@Override
public Canvas updateRecordComponent(ListGridRecord record, Integer colNum, Canvas component, boolean recordChanged) {
if (record.getIsGroupSummary())
return null;
String fieldName = this.getFieldName(colNum);
if (buttonField.equals(fieldName) && WidgetUsed.canSeeButton(record)) {

setGroupValueFunction(new GroupValueFunction() {
@Override
public Object getGroupValue(Object value, ListGridRecord record, ListGridField field, String fieldName, ListGrid grid) {
// Many if-else conditions...
return null;
}
});
}
}
}
class WidgetUsed {
public static boolean canSeeButton(ListGridRecord r) {
// If-else...
return true;
}
}
-If I remove "setGroupValueFunction"
-If button is visible to all records
I hope you have enough information to detect the problem.
