As Plugins Developer, your will find here, some details on how to implement your own Meta-Attribute Editor dedicated to your custom Meta-Attribute.

How to extend Meta-Attributes Editors

To append a new Meta-Attributes Editors, you will have to process as follow ...

• Create a Velocity template providing the Attrbibute Editor
  
  See below the Boolean editor
  

  Code Block
  language xml
  <td class="fieldLabelArea">$i18n.getText("minyaa.workflows.attribute.booleanValue")</td> <td class="fieldValueArea"> <input type="radio" name="metaAttributeBooleanValue" id="attributeRadioValue1" size="30" value="true" /> <label for="attributeRadioValue1"> $i18n.getText("admin.common.words.true")</label> <input type="radio" name="metaAttributeBooleanValue" id="attributeRadioValue2" size="30" value="false" /> <label for="attributeRadioValue2"> $i18n.getText("admin.common.words.false")</label> <br /> </td>

  
  
  
• Create a Javascript applying the edited value into the Input field.
  
  ... always for Boolean editor
  

  Code Block
  language javajs
  jQuery(document).ready(function(){ MYAAWA.namespace("MYAAWA.Editors.editMetaBoolean"); MYAAWA.Editors.editMetaBoolean.init = function(inputValue) { var editedValue = AJS.$("[name='metaAttributeBooleanValue']"); var onChanged = function(event) { inputValue.val(event.target.value); }; MYAAWA.Editors.editMetaBoolean.onChanged = onChanged; editedValue.change(MYAAWA.Editors.editMetaBoolean.onChanged); }; });

  
  
  
• Define a Web Resource for this JS file. It has to be in dependency with MYAA_WorkflowsAttribute.js
  
  ... again for Boolean editor
  

  Code Block
  language xml
  <web-resource key="MYAA_editMetaBoolean" name="MYAA-editMetaBoolean"> <dependency>jira.plugin.minyaa.workflows.attributes:MYAA_WorkflowsAttributes</dependency> <resource type="download" name="editMetaBoolean.js" location="com/minyaa/workflows/js/MYAA.editMetaBoolean.js"> <property key="content-type" value="text/javascript"/> </resource> <context>atl.admin</context> </web-resource>

  
  
  
• and finally, defined the meta-editor, specifying the related Velocity template
  
  ... a last one for Boolean editor
  

  Code Block
  <meta-editor key="editMetaBoolean" name="Edit Meta Attribute as Boolean"> <resource type="velocity" name="edit" location="com/minyaa/workflows/templates/meta-attributes-edit-boolean.vm"/> </meta-editor>

   

How to extend Meta-Attributes

To extend the list of displayed Meta-Attributes depending on the list of supported process as follow ... Use the custom plugin module-type meta-attribute

<meta-attribute key="sampleAttribute" name="sample.attribute" isUnique="false"   valueEditorKey="jira.plugin.minyaa.workflows.attributes:editMetaBoolean" >
02.
	<description key="sample.attribute.desc">Do nothing !.</description>
03.
<scope   	<scope
		initialAction="true"
04.
		globalAction="true"
05.
		commonAction="true"
06.
		stepAction="true"
07.
		initialStep="true"
08.
		normalStep="true"
09.
		finalStep="true"
10.
	/>
11.
</meta-attribute>

Where ...

• isUnique specifies if the attribute may be use more than one time by Step of Transition (Not yet completely supported),
• valueEditorKey specifies the editor to use. Use the complete key.
• scope specifies if the attribute can be use as Step Meta-Attribute or Transition Meta-Attribute
  
  Different types of Step and Action are possible, but will managed only by Minyaa Workflows Designer

Meta-Attributes may be also added through a Plugin Component. The Component will have to implement the interface MetaAttributesProvider as follow ...

public class YourMetaAttributesProvider implements MetaAttributesProvider {

private MetaAttributeManager metaAttributeManager;
 
	public WorkflowMetaAttributesProvider(MetaAttributeManager metaAttributeManager) {
		this.metaAttributeManager = metaAttributeManager;
		metaAttributeManager.addMetaAttributesProvider(this);
	}
 
	public void refresh() {
		MetaAttributeModule metaAttributeModule;
 
		metaAttributeModule = new MetaAttributeModule("sample.step.attribute");
		metaAttributeModule.appendDescription("Do nothing special").appendScopes(metaAttributeManager.getAllAvailableStepScopes());
		metaAttributeModule.appendValueEditorKey("jira.plugin.minyaa.workflows.attributes:editMetaBoolean");
		metaAttributeManager.addMetaAttributes(metaAttributeModule);
 
		metaAttributeModule = new MetaAttributeModule("new.boolean.action.attribute");
		metaAttributeModule
			.appendDescription("Define if it is True or False !!!")
			.appendScopes(metaAttributeManager.getAllAvailableActionScopes());
		metaAttributeModule.appendValueEditorKey(MetaAttributeManager.META_VALUE_EDITOR_BOOLEAN_KEY);
		metaAttributeManager.addMetaAttributes(metaAttributeModule);
	}
}
