Method Summary

protected void	checkUpdateModelError(javax.faces.context.FacesContext context) This method is used when a custom processUpdates and processValidators is defined, to check if a update model error forces the render response for our data, because _isValidChilds is a private field and is not available on child components that inherits this component class like t:dataList.
void	clearRowStates() Remove all preserved row state for the dataTable
protected javax.faces.model.DataModel	createDataModel() Creates a new DataModel around the current value.
void	deleteRowStateForRow(int deletedIndex) Remove preserved row state for deleted row and adjust row state to reflect deleted row.
void	encodeBegin(javax.faces.context.FacesContext context)
void	encodeEnd(javax.faces.context.FacesContext context)
String	getClientId(javax.faces.context.FacesContext context) Hack since RI does not call getRowIndex()
protected javax.faces.model.DataModel	getDataModel()
String	getDerivedRowKeyPrefix() This attribute is used to append an unique prefix when rowKey is not used, to prevent a key match a existing component id (note two different components can't have the same unique id).
protected String	getDerivedSubClientId() Return the fragment to be used on the container client id to identify a row.
int	getRowCount()
Object	getRowData()
int	getRowIndex()
Object	getRowKey() Used to assign a value expression that identify in a unique way a row.
protected boolean	hasErrorMessages(javax.faces.context.FacesContext context)
boolean	isForceId() If true, this component will force the use of the specified id when rendering.
boolean	isForceIdIndex() If false, this component will not append a '[n]' suffix (where 'n' is the row index) to components that are contained within a "list." This value will be true by default and the value will be ignored if the value of forceId is false (or not specified.)
boolean	isPreserveRowStates() Indicates whether the state for each row should not be discarded before the datatable is rendered again.

public HtmlDataTableHack()

Method Detail

isRowAvailable

public boolean isRowAvailable()

Overrides:

isRowAvailable in class javax.faces.component.UIData

getRowCount

public int getRowCount()

Overrides:

getRowCount in class javax.faces.component.UIData

getRowData

public Object getRowData()

Overrides:

getRowData in class javax.faces.component.UIData

getRowIndex

public int getRowIndex()

Overrides:

getRowIndex in class javax.faces.component.UIData

getClientId

public String getClientId(javax.faces.context.FacesContext context)

Hack since RI does not call getRowIndex()

Overrides:

getClientId in class javax.faces.component.UIData

processUpdates

public void processUpdates(javax.faces.context.FacesContext context)

Overrides:

processUpdates in class javax.faces.component.UIData

See Also:

UIData.processUpdates(javax.faces.context.FacesContext)

checkUpdateModelError

protected void checkUpdateModelError(javax.faces.context.FacesContext context)

This method is used when a custom processUpdates and processValidators is defined, to check if a update model error forces the render response for our data, because _isValidChilds is a private field and is not available on child components that inherits this component class like t:dataList. (TOMAHAWK-1225)

processValidators

public void processValidators(javax.faces.context.FacesContext context)

Overrides:

processValidators in class javax.faces.component.UIData

See Also:

UIData.processValidators(javax.faces.context.FacesContext)

encodeBegin

public void encodeBegin(javax.faces.context.FacesContext context)
                 throws IOException

Overrides:

encodeBegin in class javax.faces.component.html.HtmlDataTable

Throws:

IOException

See Also:

UIData.encodeBegin(javax.faces.context.FacesContext)

setPreserveRowStates

public void setPreserveRowStates(boolean preserveRowStates)

isPreserveRowStates

public boolean isPreserveRowStates()

Indicates whether the state for each row should not be discarded before the datatable is rendered again. Setting this to true might be hepful if an input component inside the datatable has no valuebinding and the value entered in there should be displayed again. This will only work reliable if the datamodel of the datatable did not change either by sorting, removing or adding rows. Default: false

hasErrorMessages

protected boolean hasErrorMessages(javax.faces.context.FacesContext context)

encodeEnd

public void encodeEnd(javax.faces.context.FacesContext context)
               throws IOException

Overrides:

encodeEnd in class javax.faces.component.UIData

Throws:

IOException

See Also:

UIComponentBase.encodeEnd(javax.faces.context.FacesContext)

setRowIndex

public void setRowIndex(int rowIndex)

Overrides:

setRowIndex in class javax.faces.component.UIData

                                                boolean restoreChildFacets)

setValue

public void setValue(Object value)

Overrides:

setValue in class javax.faces.component.UIData

getDataModel

protected javax.faces.model.DataModel getDataModel()

setDataModel

protected void setDataModel(javax.faces.model.DataModel datamodel)

createDataModel

protected javax.faces.model.DataModel createDataModel()

Creates a new DataModel around the current value.

saveState

public Object saveState(javax.faces.context.FacesContext context)

Specified by:

saveState in interface javax.faces.component.StateHolder

Overrides:

saveState in class javax.faces.component.html.HtmlDataTable

restoreState

public void restoreState(javax.faces.context.FacesContext context,
                         Object state)

Specified by:

restoreState in interface javax.faces.component.StateHolder

Overrides:

restoreState in class javax.faces.component.html.HtmlDataTable

isForceId

public boolean isForceId()

If true, this component will force the use of the specified id when rendering.

Specified by:

isForceId in interface ExtendedComponentBase

Returns:

setForceId

public void setForceId(boolean forceId)

Specified by:

setForceId in interface ExtendedComponentBase

isForceIdIndex

public boolean isForceIdIndex()

If false, this component will not append a '[n]' suffix (where 'n' is the row index) to components that are contained within a "list." This value will be true by default and the value will be ignored if the value of forceId is false (or not specified.)

Returns:

setForceIdIndex

public void setForceIdIndex(boolean forceIdIndex)

clearRowStates

public void clearRowStates()

Remove all preserved row state for the dataTable

deleteRowStateForRow

public void deleteRowStateForRow(int deletedIndex)

Remove preserved row state for deleted row and adjust row state to reflect deleted row.

Parameters:

deletedIndex - index of row to delete

getRowKey

This attribute is used to append an unique prefix when rowKey is not used, to prevent a key match a existing component id (note two different components can't have the same unique id).

Returns:

setDerivedRowKeyPrefix

public void setDerivedRowKeyPrefix(String derivedRowKeyPrefix)

getDerivedSubClientId

protected String getDerivedSubClientId()

Return the fragment to be used on the container client id to identify a row. As a side effect, it will be used to indicate a row component state and a datamodel in nested datatable case.

The returned value must comply with the following rules:

• Can be followed by: letters (A-Za-z), digits (0-9), hyphens ("-"), underscores ("_"), colons (":"), and periods (".")
• Values are case-sensitive
