Generates a single HTML checkbox. The <netui:checkBox> tag should be used on its own, not within a <netui:checkBoxGroup> .
The <netui:checkBox> tag can be data bound to a boolean or Boolean type. For instance, the following <netui:checkBox> tag...
<netui:checkBox dataSource="{actionForm.checkBoxValue}"/>...must be bound to a boolean or Boolean field in the Form Bean...
public static class ProcessDataForm extends FormData { private boolean checkBoxValue; public void setCheckBoxValue(boolean checkBoxValue) { this.checkBoxValue = checkBoxValue; } public boolean isCheckBoxValue() { return this.checkBoxValue; } }

Then the following <netui:textBox> tag will (1) draw populating data from the Form Bean's foo property and (2) submit user defined data to the same property. The When the tag is used to submit data, the data binding expression must refer to a Form Bean property. In cases where the tag is not used to submit data, but is used for displaying data only, the data binding expression need not refer to a Form Bean property. For example, assume that myIterativeData is a member variable on the Controller file ( = JPF file). The following <netui-data:repeater> tag draws its data from myIterativeData. |
