Is it possible to lanch the workflow initiation form in modal window?

Question

I want to have the initiation form inside a modal popup. Here's what I've figured out so far:

To open the form insisde a modal dialog, I've included this inside the "Navigatate to Url" in the custom action.

javascript:function openDialog() {  
    var options = { 
    url: "http://<server>/srd/Workflows/wf_lobEnd/wf_lobEnd.aspx",
    width: 800,
    height: 600,
    title: "User Story"
    };
    SP.UI.ModalDialog.showModalDialog(options);
}
openDialog();

This works fine. Question is how to modify the wf_lobend.aspx form so that the popup closes, and the initiation form get submitted.

This is the javascript that gets generated for me behind the ok buttun of the initiation form:

            <input type="button" value="Start" name="btnSave" onclick="javascript: {ddwrt:GenFireServerEvent(concat('__insert;__commit;__redirectsource;__redirectToList={',ddwrt:EcmaScriptEncode($ListName),'};'))}" />

That is a bit cryptic to me, so I'm not sure what to replace. I know that I must use something like this to get the dialog closed, but that does not seem to submit the form:

onclick="SP.UI.ModalDialog.commonModalDialogClose(SP.UI.DialogResult.OK, 'Ok clicked'); return false;"

Question is: How to close the dialog and still post the data?

(or maybe I've take the complete wrong approach, in case please let me know)

Answer 1

I have done something similar, starting a workflow from a modal dialog. The form that i used does not have any fields, but it still posts back and starts the workflow.

http://djeeg.blogspot.com/2010/11/sharepoint-designer-custom-action-in.html

The code i used to open the dialog is this

SP.UI.ModalDialog.showModalDialog({
    url:"{SiteUrl}/_layouts/Com.CodePlex.SPC3/StartWorkflow.aspx?List={ListId}&ItemID={SelectedItemId}&Workflow=WorkflowName",
    dialogReturnValueCallback: function(dialogResult, returnValue) { 
        SP.UI.ModalDialog.RefreshPage(SP.UI.DialogResult.OK) 
    }
})

Try adding the dialogReturnValueCallback property to the open dialog options. I did not have to modify any of the automatically generated dialog button javascript.

EDIT

Though looking at the page source i did have to do something extra to get it to redirect

if (Request["IsDlg"] == "1") {
    Context.Response.Write("<script type='text/javascript'>window.frameElement.commitPopup();</script>");
    Context.Response.Flush();
    Context.Response.End();
} else {
    SPUtility.Redirect(list.DefaultViewUrl, SPRedirectFlags.UseSource, Context);
}
