I am building a custom control that mimics the viewPanel control but it is a repeat control which data is not a view but a managed bean that returns an arraylist of java objects (representing Notes documents).
I am using a Bootstrap table for display I in a previous post I have demonstrated how I can provide a JSON object to have flexibility in the columns I want to display and the values I want to display.
Next step is the option to provide custom actions to the custom control, in a way that the code under an action button in the custom control is provided via a property. So in one case hitting the button could print all selected documents, in the other case it could remove all documents from the database.
Step 1 – Creating an arraylist of unid’s
Key here is that I have an arraylist of unid’s to work with. The technique how to select documents in a repeat control was demonstrated by David Leedy in Notes in 9 episode 25. Instead of buttons I use a checkboxgroup:
So now I want from my xp:button in my custom control do something with this arraylist of unid’s…
Step 2 – set up the property definition
Next step is to setup the property in the property definition of the custom control:
Not the most common type of class and editor you use for a property.
Step 3 – setup the event handler for the button
In order to have the button to understand that the action to be performed is coming from a action property we need to specify that in the onClick event:
(Note: my property resides in the group property actionButton)
Step 4 – set up the SSJS function you want to run
So now our button knows it’a action comes from a propert we need to write the SSJS function for the button. I have placed it in a SSJS script library. Here is an example to remove documents from a database:
Step 5 – Add the SSJS to the property
The last step is the most tricky one. In the property you are not allwed to provide any parameters or parentheses for the SSJS function. So our action property becomes as followed:
As a result I have the following UI:
- A custom control with a button which onClick action is provided via a property on that host xpage.
