Data tags consist in names of dataproviders surrounded by %%. Standard tags are a set of predefined tags that are made available by the system.

See the "Merging data" section for more details about tags.

Using the group itself, all components can be disabled/enabled or made invisible/visible. The group id should be a javascript compatible identifier to allow access of the group in scripting.

Type String

Sample

height

The height in pixels of the component.

Sample

labelFor

Some components can be set to be labels of other components. This is useful in two situations. In table view mode it is used for constructing the header of the table. In record view mode, by setting mnemonics on the label, keyboard shortcuts can be used to set the focus to fields.

Type String

Sample

margin

Type String

Sample

mediaOptions

Options to scale the image Media object that is displayed inside the component. Can be set to one or a combination of CROP, REDUCE, ENLARGE and KEEPASPECT.

REDUCE will scale down the image if the component is smaller than the image. REDUCE combined with KEEPASPECT will reduce the image, but keep its aspect ratio. This is useful when the component has other proportions than the image.

ENLARGE will scale up the image if the component is larger than the image. ENLARGE combined with KEEPASPECT will scale up the image while keeping its aspect ratio.

CROP will leave the image at its original size. If the component is smaller than the image this will result in only a part of the image showing up.

Type Number

Sample

mnemonic

Sample

styleClass

The name of the style class that should be applied to this component.

When defining style classes for specific component types, their names must be prefixed according to the type of the component. For example in order to define a class names 'fancy' for fields, in the style definition the class must be named 'field.fancy'. If it would be intended for labels, then it would be named 'label.fancy'. When specifying the class name for a component, the prefix is dropped however. Thus the field or the label will have its styleClass property set to 'fancy' only.

A value of 0 means to use the default mechanism of building the tab sequence (based on their location on the form). A value of -2 means to remove the component from the tab sequence.
