• Flex way of Deploying DSC on LiveCycle.

  Problem

  In order to deploy the DSC the most easy way is to have a Workbench installed. But there are also ways to deploy a DSC without having WorkBench by our side. In Java, we do so by the help of LC SDK jars, namely adobe-livecycle.jar and adobe-usermanagement-client.jar. Now, what if we want to deploy a DSC from a FLEX UI on a Livecycle Server, running somewhere remote, let say by the click of a button on an AIR App. But in Flex we can't use SDK jars, hence the creation of ServiceClientFacory is impossible.

  Solution

  Flex exposes remoting endpoint which can be used to communicate with LiveCycle via LCDS. The adobe-remoting-provider.swc whihc is used to facilitate the communication, can be found at the LiveCycle installed location, \\Adobe LiveCycle ES2\LiveCycle_ES_SDK\misc\DataServices\Client-Libraries.

• How to display toolTip message for each nodes shown in Tree control

  Problem

  The Tree control has 'toolTip' property. But it is applied for Tree control itself, not for each nodes shown in the control. In addition, the control does not have any methods to show toolTip hint as you want. Thus, the property is difficult to show toolTip message for each nodes dynamically.

  Solution

  Here is the workaround for the above problem: When the 'Tree.itemRollOver' event is fired, you can refer the node which is rolled over by user.Thus, you can get text of the node to show it as toolTip.

  When using mouseDownOutside with PopUpAnchor, clicking the toggle button was not closing the PopUpAnchor Popup.

• How to create object from string of class name

  Problem

  Hi people. I'm trying to create an object at runtime, just passing the classname as a parameter I already tried that with a standard Flex Component and it worked very well. BUT, when I try to do this with one of my components, an error occurs: ReferenceError: Error #1065: Variable [myComponentClassName] is not defined. Thanks.

  Solution

  Did you make sure your class is getting compiled ? Because if it's not referenced anywhere else in the application it is not compiled, and thus it is not possible to create any instance of it.
