What It Is
Click to Open (C2O) allows you to open components in Eclipse directly from the running application in your browser! Click to Open appears in the lower left corner of browser as part of the pages of your running application. Clicking on this component, and then on an object in the browser window, opens the relevant WOComponent in Eclipse. This makes life easier for UI designers and for developers getting familiar with new projects. It also provides some other very slick debugging tools.

Click to Open is a browser based extension to WOLips found in Project Wonder. All of the Wonder ERD2W components support Click to Open.
Note that click-to-open support is expensive, because it has to dig around your component HTML quite a bit, so you will take a performance hit in development to have it enabled.
What You Need
You need the WOLips framework that is part of Project Wonder. You also need the ERExtensions framework that is part of Project Wonder on the class path at runtime. If you already use Project Wonder, you are almost done.
If you are not using Project Wonder, you can download it from mDimension's site, untar the frameworks, and copy just the WOLips.framework and ERExtensions.framework to where you have the rest of your frameworks (usually /Library/Frameworks or ~/Library/Frameworks).
Getting Set Up
Add the WOLips.framework
Follow the tutorial on adding a framework to add WOLips.framework and ERXExtentions.framework to your application.
Add Support to Component Base Class
If your components extend Wonder's ERXComponent, you can skip this step. Once again, using Wonder makes your life easier.
If you don't have a custom component base class, you really should. Using com.webobjects.appserver.WOComponent as the super-class for your pages and components is just going to leave you doing the same things over and over. If you don't have one, you might want to start using the ClickToOpenComponent below.
You will need to add the appendToResponse(WOResponse, WOContext) method below to your component base class, or add this code to your appendToResponse method if you already have one.
Here is an example implementation of a component base class and of Click to Open support:
For components that can't sub-class ClickToOpenComponent (directly or indirectly), you can enable Click to Open by adding this method to your component:
Note that when isClickToOpenEnabled is false, the ERXClickToOpenSupport methods are no-ops.
Add Support to Application
If your Application.java class extends Wonder's ERXApplication, you can skip this step too. Otherwise, add a developmentMode() method like this:
Set Application Properties
In your application's Properties file, add this line:
If you need to, you can also change these default values:
WOLips.framework needs a prototype.js. If you are using Ajax framework, you don't need to do anything, because it will default to use Ajax.framework's prototype.js. However, if you are not, add this to your application's Properties file (as an example, change the values as appropriate):
Add WOLToolBar to Your Pages
In your page wrapper's HTML template, add
and you're done. If you don't have a page wrapper, you will have to add this to every page. Hint: page wrappers make your life easier.
If you are using the old WO template syntax, add this to the .html file:
And add this to the .wod file:
Configure WOLips Server
You must be using a recent version of WOLips that supports the WOLips Server. In your WOLips preferences, you must enable the WOLips Server and set the communication password. This password must match the
wolips.password in the Set Application Properties section above.
Turning on the WOLips Server requires Eclipse to be restarted.
You can optionally change the port number. If you do change the port number, see
wolips.port in the Set Application Properties section above.
Enable Click to Open
If you are using Wonder, add the following to your Properties file:
If you are not using Wonder, add the Launch parameters as follows:
- Parameter = -Der.component.clickToOpen=true, Argument = true
- Parameter = -Der.extensions.ERXApplication.developmentMode=true Argument = true
(needing to have "true" twice is a minor bug. The really important one is the first one)
Using Click to Open
Run your application and look in the lower, left hand corner. You should see a link like this:
If you don't, check that the page has the WOLToolBar on it and that the
er.component.clickToOpen property is set to true and the
er.extensions.ERXApplication.developmentMode property is set to true.
Click on this component to open the Click to Open UI:
EditDisplayAd is the page in the browser. Click on this link to open this page in Eclipse.
If you are looking for a sub-component of this page, click on the Click to Open link. As you move your mouse over the page, the bread crumb of components will change to show you where you are. Just click to open the component under the mouse in Eclipse. It is that easy!
- Esc is a shortcut for getting out of click-to-open mode
- hold down the Cmd key while you move the mouse around and it will highlight the component
- Cmd-click it will popup the stack of components and you can pick from the stack:
- you can set the binding
expanded=true;on WOLToolBar so it's open by default, instead of closed
