setClientEvent() in Browser Tree - Webtop 6.5SP1

We are doing a customization of Webtop (6.5 SP1 version) DRL component. We are adding a custom button called "Locate" similar to View and Edit in the drl.jsp. The functionality on click of Locate button is to search for the document (r_object_id) and its parent Cabinet to be displayed similar to the one in the Webtop Search result set (Browser Tree on the left panel and the searched documents in the workarea frame).

The search is working at the first hit of DRL and all other remaining hits are directly landing in the default main component without invoking the setClientEvent() method described in Step-2 below.

The way we have implemented is as follows.

1) In the custom DRLComponent.java, call Set Component Jump to "main" component.

setComponentJump("main", argumentlist, getContext());

2) I have extended BrowserTree.java to custom layer and doing a setClientEvent() to invoke a client event registered in the classic.jsp page. Please note that I am triggering this setClientEvent() in the onInit() method of BrowserTree.java.

setClientEvent("onLocateDoc", argumentlist);

3) My classic.jsp has got a <script> which follows like this

registerClientEventHandler("browser", "onLocateDoc", onLocateDoc);
function onLocateDoc(objectId) {
    var bContentReady = frames["workarea"].contentReady;
    if (bContentReady != true) {
        setTimeout("onLocateDoc(\"" + objectId + "\")", 500);
        return;
    }
    var query = "select * from dm_folder where r_object_id in (select distinct i_folder_id from dm_document where r_object_id='" + objectId + "') union select * from dm_document (all) where r_object_id='" + objectId + "'";
    postComponentJumpEvent(null, "nsearch", "content","queryType", "dql", "query", query);
}
</script>

4) I invoke my "nsearch" component using the postComponentJumpEvent() method. The nsearch is a simple search component extending Simple Search Component.

Please let me know whether this approach is right or is there any other approaches for implenting the above mentioned functionality.

The customer requirement is to display the DRL locate search to be displayed in the Main component layout. Otherwise in the Step-1 mentioned above, I can do a setComponentJump("nsearch") and the result is appearing but in a full window.

Your help is greatly appreciated.

Hi,

Approach is partially correct. The code block implemented will be called only once as onInit method will called once the Browsertree components gets initialized.

What you can do is in drl.jsp, since you have added a new button "locate", add handler method for the click event on this button say - onLocateClicked. You can extend the component class DRLComponent and add the above method in the the class. In the onLocateClicked method, you can use ActionService to execute the custom search action class and get the results displayed in the workarea. With this approach you are adhering to WDK framework calls and hence framework will manage intricacies involved such as showing up browsertree, to launch the main component with searchresults in the same page rather than launching a new window to show results.

Skeleton of the impl -

MyDRLComponent extends DRLComponent {

public void onLocateBtnClicked {

// do necessary validation

....

// call the action id that does the seach & result fetch See WDK Developers' guide on how to write custom actions

executeAction("drlseach")

}

private void executeAction(String strActionId)
{

IActionCompleteListener completeListener = null;

         completeListener = new DRLLogoffOnComplete();
         actionArgs.add("navigateOnComplete", "false");
        }

ActionService.execute(strActionId, actionArgs, getContext(), this, completeListener);
}

}
