Reading from screen fields

Dimitris Xernos

Hi.

I have developed a plugin with a listener which is able to catch the events fired in JIRA.

I want when special events are fired, to read the values of specific fields of a screen and pass them to an external database.

I haven't found any documentation about how I could the read the values from the fields of a screen.

Can you guide what classes I could use for this ?

Thanks for your help.

Hi, you can use change items to detect fields.

try {
	// Read change items, comment 
	List<GenericValue> changeItems = event.getChangeLog().getRelated("ChildChangeItem");
	Comment comment = event.getComment();
					
	String field, fieldType; 
	for (GenericValue changeItem : changeItems) {
		fieldType = (String) changeItem.get("fieldtype");
		field = (String) changeItem.get("field"); // Field Name
		// Collection of all fields with the same name!
		Collection<CustomField> cfCol = Helper.getCustomFieldByName(field);
		// ...
					
		// Detect attachment
		if (Constants.CHANGE_ITEM_FIELD_TYPE_JIRA.equalsIgnoreCase(fieldType) && // JIRA
			Constants.CHANGE_ITEM_FIELD_ATTACHMENT.equalsIgnoreCase(field)) {	 // Attachment
						
			Object attachmentId = changeItem.get("newvalue");
			if (attachmentId != null && attachmentId.toString().length()>0) {
				// Attachment Add
				try {
					Attachment attachment = ComponentAccessor
						.getAttachmentManager().getAttachment(Long.valueOf(attachmentId.toString()));
					// Action
				}
				catch (DataAccessException dae) {
					error("Unable to access attachment with id:" + attachmentId.toString() + "!", dae);
				}
			}
			else {
				// Attachment Delete, no WS interface method
				attachmentId = changeItem.get("oldvalue");
				debug("Attachment with id:" + attachmentId.toString() + " delete action is not sychronized.");
			}
		}
		else {
			// Read value from changed field + operation					
		}
	}
} catch (GenericEntityException gee) {
	log.error("Can not read change items list!", gee);
}
