dynamic ExtendedDataTable filtering

[elf]

Hi

Help me please. I am new to richfaces.
I created dynamically ExtendedDataTable, but I do not see filter field. When I did it using web component everything was fine and I had possibility to filter my data. Dynamically I filled the same properties.
Is there some trick to display filter field creating ExtendedDataTable dynamically?
I see a lot of examples using web components. Is there knowledge base how to work with richfaces dynamically ? Some books, articles or someting else?

Thank you in advance.

Hello,

There's nothing special in creating components dynamically, probably you haven't filled some necessary attribute. Please post your bean code.

Here is my code. I use 3.3.0 version. Please point.

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

 HtmlExtendedDataTable list = new HtmlExtendedDataTable();
 list.setId("clUserList");
 list.setValueExpression("value",
 elFactory.createValueExpression(elContext, "#{extendedDataTableBean.dataModel}", ExtendedTableDataModel.class));
 list.setWidth("100%");
 list.setHeight("200px");
 list.setSelectedClass("dataTableSelectedRow");
 list.setSortMode("single");
 list.setSelectionMode("single");
 list.setValueExpression("selection",
 elFactory.createValueExpression(elContext, "#{extendedDataTableBean.selection}", SimpleSelection.class));
 list.setRowKeyVar("rkvar");
 list.setValueExpression("tableState",
 elFactory.createValueExpression(elContext, "#{extendedDataTableBean.tableState}", String.class));
 list.setVar("item");

 HtmlColumn idCol = new HtmlColumn();
 idCol.setId("clUserListId");
 ValueExpression idExpr = elFactory.createValueExpression(elContext, "#{item.id}", String.class);
 idCol.setHeaderClass("dataTableHeader");
 idCol.setWidth("150px");
 idCol.setLabel("ID");
 HtmlOutputText idContent = new HtmlOutputText();
 idContent.setValueExpression("value", idExpr);
 idCol.getChildren().add(idContent);
 HtmlOutputText idHeader = new HtmlOutputText();
 idHeader.setValue("ID");
 idCol.getFacets().put("header", idHeader);
 list.getChildren().add(idCol);

 HtmlColumn nameCol = new HtmlColumn();
 nameCol.setId("clUserListName");
 ValueExpression nameExpr = elFactory.createValueExpression(elContext, "#{item.name}", String.class);
 nameCol.setHeaderClass("dataTableHeader");
 nameCol.setWidth("150px");
 nameCol.setLabel("Name");
 nameCol.setSelfSorted(false);
 nameCol.setSortBy(nameExpr);
 nameCol.setFilterBy(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);
 list.getChildren().add(nameCol);

I tried to use

nameCol.setSelfSorted(true);

and

nameCol.setSortable(true);

also

Try this:

nameCol.setValueExpression("filterBy", nameExpr)

It works now.
Thank you.

One more question. Help me please.

I tried to use 1 bean for 2 extendedDataTables (I have selector between different data in extendedDataTable model).
But I can not.
I pressed button A and first table displayed successfully.
I pressed button B and displayed second table but there was data of first table. It looks like some cash is used.
In logs I found that when second table displayed, application did not call my extendedDataTable model methods.
All my code is above. ExtendedDataTable Model I created as in richfaces samples.

Should I redefine some methods in ExtendedDataTable bean and use there my selector between different data
or is there way not to use cash (data always load from model)
or are there another ways to use 1 bean for 2 tables?

Please help.

Please post page code.

Problem is solved.
I have used reset() method for exTableData model.
