[jboss-jira] [JBoss JIRA] Resolved: (JBRULES-432) DSL aware editor

DSL aware editor ---------------- Key: JBRULES-432 URL: http://jira.jboss.com/jira/browse/JBRULES-432 Project: JBoss Rules Issue Type: Sub-task Security Level: Public(Everyone can see) Components: drools-brms Reporter: Michael Neale Assigned To: Michael Neale In this editor, drop downs will be provided to choose expressions from the lists of templates (it won't be a text editor), with the "data" being populated with a text box. The work for parsing can be done server side, the editor only has to display+capture data values from the user. A basic implementation would be something like: * A DSL aware editor would be good. This works as the following (assuming Google GWT): - Is implemented as a subclass of Widget or Composite in GWT (refer to the GWT manual) -Takes in a DSL via public methods: setDSLConditionList(String[] list) and setDSLActionList(String[] list) for completion lists. -Takes in rule in the form of: -setLHS(String[]) -lists of conditions -setRHS(String[]) - list of actions -After a rule has been edited, the resulting text can be obtained by String getLHS(), getRHS etc. -User can chose an icon to popup a list of conditions to add, actions to add (chosing from respective list) -User can chose to remove a condition, or an action (by clicking on a "-" next to a condition or action) COMPLEX BITS: -User can choose to edit a line of the rule (if they are allowed to). In this case, it may get a bit complicated. It may go back to the server and get a list of labels/fields which it can then display to the user so they only edit the fields. An alternative, is to do some processing on the server before the rule is loaded, and provide all the lines not as a string, but as a list of labels/fields.
