Assignee: Nick Belaevski
Priority: Minor (was: Major)
> 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
> Components: component-tables
> Affects Versions: 3.3.1
> Environment: JBoss 4.2
> Reporter: Mustafa Var
> Assignee: Nick Belaevski
> Priority: Minor
> Fix For: Future
>
> Attachments: extendedDataTable_noData.jpg
>
>
> 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.
