Custom Part Creation [message #711551]

Hello,

Can anyone tell me how to create a custom part, I have a requirement where
I need to create a Custom Property editor which by default needs to provide
me couple labels and text controls like below

LABEL 1 : TEXT-FIELD-ONE
LABEL 2 : TEXT-FIELD-TWO

Ultimately when I save/persist the value text-field-one and text-field-two
value will be merged together as single value for the property field.

The reason for me going with content assist is that I need the two - fields
to be created automatically and in one of the fields I want to provide the
Java Content Assist feature.

Please correct me if my approach is wrong and is there any better approach
for my requirement.

You can implement your own property editor by extending PropertyEditorRenderer and PropertyEditorRendererFactory classes, and then specifying that your implementation should be used like so...

<property-editor>
    <property>MyProperty</property>
    <hint>
        <name>factory</name>
        <value>MyCustomPropertyEditorFactory</value>  <!-- subject to import directives -->
    </hint>
</property-editor>

Writing a new property editor isn't easy. See various existing implementations of PropertyEditorRenderer in the framework to gauge the scope of the effort.

I think a better way to achieve this result would be to do the merging/parsing at the model level. Create two separate properties and then create custom XML binding instead of using the declarative variety. See @CustomXmlValueBinding and XmlValueBindingImpl.
