Major Current implementation of configuration parameter, JdbcParameter and other kind of parameter are duplicated with different XML syntax in plugin.xml.
The following XML will be changed, from:
<param id="runtime.datasource.core.jdbc.driver"> <LabelKey>PLUGINS_CORE_DATASOURCE_CORE_CONFIG_DRIVER_LABEL</LabelKey> <DescriptionKey>PLUGINS_CORE_DATASOURCE_CORE_CONFIG_DRIVER_DESCRIPTION</DescriptionKey> <Type>string</Type> <DefaultValue>com.mysql.jdbc.Driver</DefaultValue> <Validation> <mandatory/> </Validation> <Category>PLUGINS_CORE_DATASOURCE_CORE_CONFIG_JDBC_CATEGORY_DATASOURCE</Category> <Group>PLUGINS_CORE_DATASOURCE_CORE_CONFIG_JDBC_CATEGORY_DATASOURCE_GROUP_CORE</Group> <Order>10</Order> </param>
to:
<param id="runtime.datasource.core.jdbc.driver" type="string"> <label i18n="true">PLUGINS_CORE_DATASOURCE_CORE_CONFIG_DRIVER_LABEL</label> <description i18n="true">PLUGINS_CORE_DATASOURCE_CORE_CONFIG_DRIVER_DESCRIPTION</description> <validation> <mandatory/> </validation> <default-value>com.mysql.jdbc.Driver</default-value> <category i18n="true">PLUGINS_CORE_DATASOURCE_CORE_CONFIG_JDBC_CATEGORY_DATASOURCE</category> <group i18n="true">PLUGINS_CORE_DATASOURCE_CORE_CONFIG_JDBC_CATEGORY_DATASOURCE_GROUP_CORE</group> <order>10</order> </param>
There will be completion on type attribute because before we always forget for a number if it is an int, an integer or a long 
.
Validation and enumeration can now have both static implementation or Avalon based implementation.
Validator can now provide multiple error label (I18nizableText) instead of just a boolean.
With RUNTIME-268 the XML syntax can be extended for definition of parameter with additional properties.
org.ametys.runtime.util.parameter.AbstractParameterParser can therefore be used for parsing a XML configuration into a org.ametys.runtime.util.parameter.Parameter subtype.
