Invoking JAVA based action from shareUI (and param passing)

annakan — Fri, 01 Apr 2011 08:23:00 GMT

HelloOne day (yesterday) I wrote an action in java, but …Share does not support adding an action to the document library or document detail context menu.Thus, I followed http://wiki.alfresco.com/wiki/Custom_Document_Library_Action making the few adjustments because I am in 3.4d and such.I am to the

Here's the relevant part of the genericAction config, this is case for the "accept-simpleworkflow" action:

webscript:
{
   method: Alfresco.util.Ajax.POST,
   stem: Alfresco.constants.PROXY_URI + "api/",
   name: "actionQueue"
},
config:
{
   requestContentType: Alfresco.util.Ajax.JSON,
   dataObj:
   {
      actionedUponNode: asset.nodeRef,
      actionDefinitionName: "accept-simpleworkflow"
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Ignoring the ranting parts of your post, we are addressing Share extensibility over the remainder of this year. Which parts of the webapp folder did you have to edit?

What's your suggestion for configuration if not XML?

What other constructive criticism / suggestions do you have for extensions?

Thanks,
Mike

Thanks for your answer, I will look into it.

<Edited and send in MP>

Thanks a LOT for you help, I'll try to achieve what I set myself to do.

Success

I'll report here the things things I learned from MikeH post

You invoque an action through the actionQueue API
hence the

webscript : {
            method : Alfresco.util.Ajax.POST,
            stem : Alfresco.constants.PROXY_URI + "api/",
            name : "actionQueue"
         },‍‍‍‍‍

part.

You pass the name of the action in the actionDefinitionName entry of the dataObj array of the config array
You pass the noderef the action is fired upon in the actionedUponNode entry of the same array.

I suppose you can pass other parameters if your action requires it, probably keyed on the name you gave in the addParameterDefinitions method [paramList.add(new ParameterDefinitionImpl("paramName", …) ], but I did not test this yet.

For reference in 3.4 community I had to use
Alfresco.doclib.Actions.prototype.onMyAction= function DL_onMyAction, rather than Alfresco.DocumentList.prototype.onMyAction = function DL_onMyAction , a bit contrarily to what is said in
http://wiki.alfresco.com/wiki/Custom_Document_Library_Action.

A subsidiary question :

How do I pass extra parameters to the action ?

For instance my action as 3 parameters, I tried this

config : {
            requestContentType : Alfresco.util.Ajax.JSON,
            dataObj : {
               actionedUponNode : file.nodeRef,
               actionDefinitionName : "change-value-from-field-content",
               Field-To-Get-value-From : "XXX",
               Add-Or-Remove: true,
               Name-Of-Value-To-Change: "YYY"
            }‍‍‍‍‍‍‍‍‍

But nothing happens.
Really nothing. Meaning something breaks inside the script since I do not even have a "failure".

If on the contrary I remove the three last member of the json array, I DO have a failure with the message in the console that the parameter Field-To-Get-value-From is missing. (the exact parameter name inside the Java setParam call).

Commenting the first one and leaving the second one brings me back to the first behavior : silent do-nothing.

It is probably something quite obvious but …

EDIT : maybe not so obvious after all since I noticed that in your above example the "actionedUponNodeRef" of the

protected void executeImpl(Action action, NodeRef actionedUponNodeRef) {‍

function was passed as actionedUponNode ….. and changing that to actionedUponNodeRef results in a failure…
So does it mean that there is a mapping of sort between param names in javascript and param names in java ?

2 days later and none the wiser.

I tried to use the same aram structure that is used to pass parameters to server side javascript actions, both as a member of modules.actions.genericAction.params and modules.actions.genericAction.webscript.params, I also tried to pass them as modules.actions.genericAction.config.params (now I AM desesperate ), to no avail.
I traced enough jscript to know that the params where in modules.actions.genericAction.params and are now expected in modules.actions.genericAction.webscript.params for webscripts but is that the same for java-based actions ?

I don't have an fully source compiled alfresco, only the sdk but I retrieved the source code and made some search around and I did not find where parameters where marshalled out, I did find

GetMethod getGETMethod(String servicePath, List<WebscriptParam> params)
 and
 PostMethod getPOSTMethod(String servicePath, List<WebscriptParam> params)‍‍‍

in alfresco-src\HEAD\root\modules\wcmquickstart\wcmquickstartclientapi\source\java\org\alfresco\wcm\client\impl\WebScriptCallerImpl.java but did not get much further.

I changed my param names to be valid javascript identifier to be able to use them as key in the param array and tied both
paramName : "paramvalue" and "paramName":"paramValue" but I always get the same message that my first parameter, mandatory, is not found …

I am trying at the moment to get further up the un-marshalling code chain (getJsonObject(String servicePath, List<WebscriptParam> params)) to understand what is expected.

Any fresh idea is welcome, and yes it is probably obvious

Hey Annakan,

Did you find a solution to your problem of passing parameters using the post actionQueue webscript ?

I was trying to do something similar to what you required and stumbled upon the information given here:

http://wiki.alfresco.com/wiki/Rule_REST_API_Design_Notes#Post_Action_Queue

Basically, here's how to do it:

{
   "actionedUponNode" : "workspace://SpacesStore/123-123-abc",
   "actionDefinitionName": "copy",
   "parameterValues":
   {
      "destinationFolder" : "workspace://SpacesStore/123-123-123",
      "deepCopy" : false
   }
}

Hope this helps.

Hi,

On the ongoing discussion, is there a way to analyse different cases of failure from the action (if any) and call appropriate functions?
