ExtendedDataTable + datascroller

[elf]

Hi

I use Datascroller with ExtendedDataTable as described here
http://livedemo.exadel.com/richfaces-demo/richfaces/dataTable.jsf?tab=editDataTable
My table height is dynamic depending on screen height. Row count in table should be static. But, scrolling in table does not visible in this case.
If I run my application on computers with different screen size, I do not see all rows of table on smaller screen size.

Help me, please. How can I dynamically set up row count in ExtendedDataTable or how can I make scrolling visible ?

Hello,

Please post page code.

[elf]

here is my code

 private HtmlForm getDefaultList(String listId){

 ExpressionFactory elFactory = FacesContext.getCurrentInstance().getApplication().getExpressionFactory();
 ELContext elContext = FacesContext.getCurrentInstance().getELContext();

 HtmlExtendedDataTable list = new HtmlExtendedDataTable();
 list.setId(listId);
 list.setValueExpression("value",
 elFactory.createValueExpression(elContext, "#{exListManager.dataModel}", ExtendedTableDataModel.class));
 list.setWidth("100%");
 list.setHeight(getHeight());
 list.setSelectedClass("dataTableSelectedRow");
 list.setSortMode("single");
 list.setSelectionMode("single");
 list.setValueExpression("selection",
 elFactory.createValueExpression(elContext, "#{exListManager.selection}", SimpleSelection.class));
 list.setRowKeyVar("rkvar");
 list.setValueExpression("tableState",
 elFactory.createValueExpression(elContext, "#{exListManager.tableState}", String.class));
 list.setVar("item");

 HtmlColumn idCol = new HtmlColumn();
 idCol.setId(listId+"Id");
 ValueExpression idExpr = elFactory.createValueExpression(elContext, "#{item.id}", Long.class);
 idCol.setHeaderClass("dataTableHeader");
 idCol.setLabel("ID");
 idCol.setValueExpression("sortBy", idExpr);
 HtmlOutputText idContent = new HtmlOutputText();
 idContent.setValueExpression("value", idExpr);
 idCol.getChildren().add(idContent);
 HtmlOutputText idHeader = new HtmlOutputText();
 idHeader.setValue("ID");
 idCol.getFacets().put("header", idHeader);
 idCol.setWidth("50px");
 list.getChildren().add(idCol);

 HtmlColumn nameCol = new HtmlColumn();
 nameCol.setId(listId+"Name");
 ValueExpression nameExpr = elFactory.createValueExpression(elContext, "#{item.name}", String.class);
 nameCol.setHeaderClass("dataTableHeader");
 nameCol.setLabel("Name");
 nameCol.setSelfSorted(true);
 nameCol.setValueExpression("filterBy", nameExpr);
 nameCol.setValueExpression("sortBy", nameExpr);
 nameCol.setFilterEvent("onkeyup");
 HtmlOutputText nameContent = new HtmlOutputText();
 nameContent.setValueExpression("value", nameExpr);
 nameCol.getChildren().add(nameContent);
 HtmlOutputText nameHeader = new HtmlOutputText();
 nameHeader.setValue("Name");
 nameCol.getFacets().put("header", nameHeader);
 nameCol.setWidth("100%");
 list.getChildren().add(nameCol);

 list.getFacets().put("footer", getDatascroller(list));

 HtmlForm listForm = new HtmlForm();
 listForm.getChildren().add(list);

 return listForm;

 }

 private HtmlDatascroller getDatascroller(HtmlExtendedDataTable list){
 HtmlDatascroller dScr = new HtmlDatascroller();
 dScr.setRenderIfSinglePage(true);
 dScr.setId(list.getId()+ "DataScroller");
 dScr.setBoundaryControls("auto");
 dScr.setMaxPages(Integer.parseInt(UIHelper.getResTuning().getString("data_list_max_page_count")));
 list.setRows(Integer.parseInt(UIHelper.getResTuning().getString("data_list_max_row_count")));
 return dScr;
 }

nbelaevski, Could you please help me with this issue ? What is wrong in my code?

[nbelaevski]

Hi,

The code does not give much information:
list.setHeight(getHeight());
list.setSelectedClass("dataTableSelectedRow");

Also I do not see number of rows set.

[elf]

Number of rows I set in second method
list.setRows(Integer.parseInt(UIHelper.getResTuning().getString("data_list_max_row_count")));
It is fixed. I get it from text file.
Help me please to make number of rows dynamic in table or to make scrollBar visble.

[nbelaevski]

You can do something like this: http://livedemo.exadel.com/richfaces-demo/richfaces/actionparam.jsf?c=actionparam&tab=usage, the 3rd example. Add this to a4j:jsFunction and call it on load, re-rendering data table with the appropriate number of rows.

Thank you, good solution.
Is non-visible scrollbar in this case issue and if yes, will it be fixed in next version ?

Scrollbar is ok on demo site: http://livedemo.exadel.com/richfaces-demo/richfaces/extendedDataTable.jsf?c=extendedDataTable&tab=usage. Please create small page reproducing the issue and post the code here. As for now I cannot reproduce the problem.
