All Implemented Interfaces:

javax.faces.component.NamingContainer, javax.faces.component.StateHolder, NewspaperTable, UserRoleAware, ExtendedComponentBase

public abstract class AbstractHtmlDataTable
extends HtmlDataTableHack
implements UserRoleAware, NewspaperTable

The MyFacesDataTable extends the standard JSF DataTable by two important features:

• Possiblity to save the state of the DataModel.
• Support for clickable sort headers (see SortHeader component).

Extended data_table that adds some additional features to the standard data_table action: see attribute descriptions for preserveDataModel, sortColumn, sortAscending and preserveSort.
Unless otherwise specified, all attributes accept static values or EL expressions.

Since:

1.1.7

setForceIdIndexFormula

public void setForceIdIndexFormula(String forceIdIndexFormula)

getForceIdIndexFormula

public String getForceIdIndexFormula()

A formula that overrides the default row index in the construction of table's body components. Example : #{myRowVar.key} Warning, the EL should evaluate to a unique value for each row !

setSortColumn

public void setSortColumn(String sortColumn)

Specify what column the data should be sorted on.

Note that calling this method immediately stores the value via any value-binding with name "sortColumn". This is done because this method is called by the HtmlCommandSortHeader component when the user has clicked on a column's sort header. In this case, the the model getter method mapped for name "value" needs to read this value in able to return the data in the desired order - but the HtmlCommandSortHeader component is usually "immediate" in order to avoid validating the enclosing form. Yes, this is rather hacky - but it works.

getSortColumn

public String getSortColumn()

Value reference to a model property that gives the current sort column name. The target String property is set to the "columnName" of whichever column has been chosen to sort by, and the method which is bound to the "value" attribute of this table (ie which provides the DataModel used) is expected to use this property to determine how to sort the DataModel's contents.

setSortAscending

public void setSortAscending(boolean sortAscending)

isSortAscending

public boolean isSortAscending()

Value reference to a model property that gives the current sort direction. The target Boolean property is set to true when the selected sortColumn should be sorted in ascending order, and false otherwise. The method which is bound to the "value" attribute of this table (ie which provides the DataModel used) is expected to use this property to determine how to sort the DataModel's contents.

setSortProperty

public void setSortProperty(String sortProperty)

The name of a javabean property on which the table is sorted.

The datamodel should contain objects that have this property; reflection will be used to sort the datamodel on that property using the default comparator for that type.

This value is part of the component state. However it is not directly settable by users; instead it is set by other components such as a CommandSortHeader.

getSortProperty

public String getSortProperty()

isSortable

public abstract boolean isSortable()

Define if the table is sortable or not

isEmbedded

public abstract boolean isEmbedded()

Avoids rendering the html table tags, thus, giving you a table rendering just rows. You can use this together with the detailStamp faces of the parent datatable to render child-tables using the same layout as the parent. Notice: You have to ensure both tables do have the same number of columns. Using the colspan attribute of the column tag might help alot.

isDetailStampExpandedDefault

public abstract boolean isDetailStampExpandedDefault()

true|false - true if the detailStamp should be expanded by default. default: false

getDetailStampLocation

public abstract String getDetailStampLocation()

before|after - where to render the detailStamp, before the actual row or after it. default: after

isDetailExpanded

public boolean isDetailExpanded()

Return true if the current detail row is expanded.

Returns:

true if the current detail row is expanded.

getSortColumnIndex

public int getSortColumnIndex()

setSortColumnIndex

public void setSortColumnIndex(int sortColumnIndex)

true is any of the details is expanded

Parameters:

expandedEmpty -

setPreserveDataModel

public void setPreserveDataModel(boolean preserveDataModel)

isPreserveDataModel

public boolean isPreserveDataModel()

Indicates whether the state of the whole DataModel should be saved and restored. When set to false, the value-binding for the "value" attribute of this table is executed each time the page is rendered. When set to true, that value-binding is only executed when the component is first created, and the DataModel state is thereafter saved/restored automatically by the component. When column sorting is used for a table this property needs to be false so that the DataModel can be updated to reflect any changes in the sort criteria. Default: false

setPreserveSort

public void setPreserveSort(boolean preserveSort)

isPreserveSort

public boolean isPreserveSort()

Indicates whether the state of the sortColumn and sortAscending attribute should be saved and restored and written back to the model during the update model phase. Default: true

isRenderedIfEmpty

public abstract boolean isRenderedIfEmpty()

Indicates whether this table should be rendered if the underlying DataModel is empty. You could as well use rendered="#{not empty bean.list}", but this one causes the getList method of your model bean beeing called up to five times per request, which is not optimal when the list is backed by a DB table. Using renderedIfEmpty="false" solves this problem, because the MyFaces extended HtmlDataTable automatically caches the DataModel and calles the model getter only once per request. Default: true

getRowIndexVar

public abstract String getRowIndexVar()

A parameter name, under which the current rowIndex is set in request scope similar to the var parameter.

getRowCountVar

public abstract String getRowCountVar()

A parameter name, under which the rowCount is set in request scope similar to the var parameter.

public abstract String getSortedColumnVar()

A parameter name, under which the a boolean is set in request scope similar to the var parameter. TRUE for the column that is currently sorted, FALSE otherwise.

getAlign
