Datascroller produces exception when table data is produced not directly from
bean constructor.
-----------------------------------------------------------------------------------------------
Key: TOMAHAWK-522
URL: http://issues.apache.org/jira/browse/TOMAHAWK-522
Project: MyFaces Tomahawk
Type: Bug
Components: Data Scroller
Versions: 1.1.3
Reporter: Guy Bashan
I have a screen with several dropdown filters that are being updated with
values dynamiclly. On each selection of one of the dropdowns the screen is
refreshed and new data is shown in the table accordingly.
Since data in table is dependant on filters, I generate the data of the table
in some dummy method right after the filters. I do it by simply putting
outputText tag:
<h:outputText value="#{bean.dummy}" />
the data of the table is produced in the dummy method and retreived with a
simple getter method:
public DataModel getData()
{
return rows;
}
I am working on the exact same code as given in myfaces examples.
When I want to move to a spacific page in the scroller, by directly pressing a
page number I get this exception:
javax.servlet.ServletException: Illegal value for first row: -10

When I generate the table in the constructor everything is working fine, but it
is impossible for me to generate the data in the constructor, since in the
constructor I still do not know the filter selections of the user.
