Method Detail

getZeroIsNull

public boolean getZeroIsNull()

If true, then when rendering, a zero is treated as a non-value, and null is returned. If false, the default, then zero is rendered as zero.

setZeroIsNull

public void setZeroIsNull(boolean zeroIsNull)

getScriptPath

public String getScriptPath()

Since:

2.2

setScriptPath

public void setScriptPath(String scriptPath)

Allows a developer to use the existing validation logic with a different client-side script. This is often sufficient to allow application-specific error presentation (perhaps by using DHTML to update the content of a <span> tag, or to use a more sophisticated pop-up window than window.alert()).

2.2

getInvalidNumericFormatMessage

public String getInvalidNumericFormatMessage()

getInvalidIntegerFormatMessage

public String getInvalidIntegerFormatMessage()

Since:

getNumberTooLargeMessage

public String getNumberTooLargeMessage()

Since:

getNumberTooSmallMessage

public String getNumberTooSmallMessage()

Since:

setInvalidNumericFormatMessage

public void setInvalidNumericFormatMessage(String string)

Overrides the invalid-numeric-format bundle key. Parameter {0} is the display name of the field.

Since:

3.0

setInvalidIntegerFormatMessage

public void setInvalidIntegerFormatMessage(String string)

Overrides the invalid-int-format bundle key. Parameter {0} is the display name of the field.

Since:

3.0

setNumberRangeMessage

public void setNumberRangeMessage(String string)

Overrides the number-range bundle key. Parameter [0} is the display name of the field. Parameter {1} is the minimum value. Parameter {2} is the maximum value.

Since:

3.0

setNumberTooLargeMessage

public void setNumberTooLargeMessage(String string)

Overrides the number-too-large bundle key. Parameter {0} is the display name of the field. Parameter {1} is the maximum allowed value.

Since:

3.0

setNumberTooSmallMessage

public void setNumberTooSmallMessage(String string)

Overrides the number-too-small bundle key. Parameter {0} is the display name of the field. Parameter {1} is the minimum allowed value.

Since:
