Is it correct for ExtendedDataTableRenderer to call getRowCount in doEncodeBegin
--------------------------------------------------------------------------------
Key: RF-7454
URL: https://jira.jboss.org/jira/browse/RF-7454
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.3.1
Environment: JBoss 4.2
Reporter: Mustafa Var
When I use <rich:extendedDataTable>,ExtendedDataModel and Modifiable for
dynamic data gathering
(I only select data in the range through DB inside ExtendedDataModel's walk()
method)
ExtendedDataTableRenderer calls getRowCount inside doEncodeBegin() method and
it checks rowCount to print the "No data" as the first row of data table.
But of course my rowCount changes when I filter data through DB(in walk
method),
however getRowCount is called inside doEncodeBegin (it is before calling walk
method)
That's why getRowCount returns the previous row count of the dataTable and
although I have data in list it sometimes prints "No data" as the first row of
data table or vice versa
(do not print "No data" although I have no data in data table)
As a workaround I check the caller of the getRowCount method in my model
implementation
public int getRowCount() {
if("ExtendedDataTableRenderer.java".equals(Thread.currentThread().getStackTrace()[4].getFileName())
&&
"doEncodeBegin".equals(Thread.currentThread().getStackTrace()[4].getMethodName())){
return 1;
}
return rowCount;
}
and I do not print "No data" at any time.
