View components
3. view components
In this chapter we eill present list of all functional element that can be used in view defining.
3.1 general structure
Every component has structure:
<component type="componentType" name="componentName" reference="referenceName" basicOptions>
// HERE YOU PUT COMPONENT CONTENT
// HERE YOU PUT ADDITIONAL OPTIONS
// HERE YOU PUT LISTENERS
// HERE YOU PUT SCRIPT
</component>
Where:
- componentType - defines type of component
- componentName - is an identifier of plugin corresponding to this view definitions
- referenceName - reference name of component. It can be used to acces component in scripts, listeners or hooks.
- basicOptions - here you put basic component options in form key="value".
Basicly addiotional option has structure:
<option type="optionType" value="optionValue" />

criteria modifiers
Criteria modifier is a hook-like method which pass SearchCriteriaBuilder used by grid component to fetch row entities and allow you to modify them. For more details and examples see 'criteria modifiers' section
3.6.2. lookup
Lookup is a component that allows user to choose related entity. It is presented as simple one-line input with entity description. User can either enter entity code from keyboard (system will automatically search corresponding entity and update this field) or choose entity from pop-up grid.
additional options
- expression - [string] expression that defies what to display in lookup when entity is selected (see expressions section).

popup options
In lookup you must define options for popup grid:
- column
- searchable
- orderable
- prioritizable
All options has the same structure as in grid component.
Popup grid has by default first column with value defined in 'fieldCode' option which will be also searchable.
row style resolvers
Lookup can mark they rows with additional CSS classes. Row style resolver is a hook-like method which gets row entity and returns set od CSS classes to be applied for. For more details and examples see 'row style resolvers' section
criteria modifiers
Criteria modifier is a hook-like method which pass SearchCriteriaBuilder used by lookup component to fetch row entities and allow you to modify them. For more details and examples see 'criteria modifiers' section
3.6.3. awesomeDynamicList
Awesome Dynamic List is complex component that can display and edit entities defined in 'has many' relation.
content
to define Awesome Dynamic List you must specify content of its elements. Structure of this definition is:
<components>
// HERE YOU PUT INNER COMPONENTS DEFINITION
</components>
where inner components are standard xml component definitions.
additional options
- hasButtons - [true | false] optional parameter that defines if list has 'new' and 'delete' buttons (default value is 'true').
- hasBorder - [true | false] optional parameter that defines if list has border
- flipOrder - [true | false] optional parameter that defines if add button prepend an element instead of append it (default value is 'false')
selection of inner Awesome Dynamic List components
Sometimes you need to select specific component inside Awesome Dynamic List Component. In example: to assign error messages or mark inputs as mandatory.
AwesomeDynamicListComponent provides two helpful methods: getComponents() which returns list of rows (each row is independent FormComponent containing components described in <components />) and getComponent(Long entityId) which returns FormComponent corresponding to entity with given id or null if not found.
Also FormComponent provides findFieldComponentByName(String name) which returns first FieldComponent that match given name.
With combination of above methods you can select specific components in given row(s). For example code below sets specific component in second row as mandatory:
AwesomeDynamicList adl = givenViewDefinitionState.getComponentByReference("ourAdlComponent");
List<FormComponent> adlRows = adl.getComponents();
FormComponent secondRowForm = adlRows.get(1);
FieldComponent someComponent = secondRowForm.findFieldComponentByName("someComponentName");
someComponent.setRequired(true);

- hasCustomActionButton - [true | false] optional parameter that defines if tree has 'custom action' (default value is 'false'). It should be used with custom translation keys - customActionTitle and customActionConfirm
- customActionIcon - [string] optional parameter that defines icon for custom action button (should be used with option hasCustomActionButton).
node type definition
To define tree you must define node types that this tree contains. Every node has structure:
<dataType name="nodeTypeName">
// HERE YOU PUT NODE TYPE OPTIONS
</dataType>
Where:
- nodeTypeName - [string] name of node type
node type options
Available node type options are:
- nodeLabelExpression - [string] expression that should be used to calculate node text value (see expressions section)
- correspondingView - [string] required option that defines name of view that is 'details view' of entities presented in this node type ('pluginName/viewName').
- correspondingComponent - [string] defines reference name of component in correspondingView to which this node type inserts it's value.
- correspondingViewInModal - [true | false] optional parameter that defines if tree should open correspondingView in modal window (default value is 'false').
