performAction

performAction(actionName, params, udpateImage)

Performs an action on the server side. This method requests a new image from the server. Optionally, new capabilities can also be requested from the server before the image is retrieved. Additional parameters are sent in the request so that an action can be performed on the server side before the capabilities and image are generated. This allows you to define a new type of interaction on the image. To implement the action on the server side, you must implement the IlvChartServerAction interface and register the action with an instance of IlvChartServletSupport. An action is defined by a name and a list of parameters.

Parameters:: actionName - The name of the action.; params - The parameters of the action as an array of strings.; udpateImage - true to update the capabilities and the image, false to update just the capabilities.

performJSFAction

performJSFAction(mb, params, udpateImage)

Performs a predefined action that invokes the specified method binding.

This action is executed before the image generation.
The signature of the method must be void methodName (IlvChart, String[]) where the first parameter is the IlvChart instance used to draw the chart and the second parameter is the array of action parameters. The action must only change the IlvChart instance as only the image is refreshed (the JSF components are not).

Parameters:: mb - The method binding to invoke.; params - The action parameters as a array of Strings.; udpateImage - true to update capabilities and the image, false to update just the capabilities.

Since:: JViews 8.0
