View flow error

Ok just for fun try this

1. Open IIS and locate the Tasklist folder

2. Right Click the folder and select properties

3. Change Execute Permissions from “Scripts and Executables” to “Scripts only”

Do IISRESET just for good measure

Rerun the K2 [blackpearl] Configuration Manager.  When you're on the step entering the information for reporting services, be sure to enter as:  http://[HOSTNAME]:[PORT]   or just http://[HOSTNAME] if a specific port is not used.

The reason for the error is that the reporting services path is most likely pointing to the reporting services web front-end, which is why it's getting text/html when it's expecting text/xml.  It needs to hit the webservice, not the website.
 

Yes, all the reports work just fine when accessing them through the workspace.  It's just when I double click on the view flow from the web part that I get the error.  Remember, when I double click on the view flow from the workspace, the reports show fine.

Thanks for your persistence on this!

When I use the workspace, the URL of the view flow (which does work) is:

http://<server>:8001/Workspace/Tasklistcontrol/ViewFlowMain.aspx?ProcessID=89&K2Server=<server>:5252

and then when I click on Process Properties, the Reporting Services report displays just fine.  The URL of the report frame is:

http://<server>:8001/Workspace/Reserved.ReportViewerWebControl.axd?ReportSession=ary2cc2rs3tjor3mdnu3ip45&ControlID=64378b877cc245778539475d3a858f69&Culture=1033&UICulture=1033&ReportStack=1&OpType=ReportArea&Controller=ClientControllerctl02_ctl00&PageNumber=1&ZoomMode=Percent&ZoomPct=100&ReloadDocMap=true&SearchStartPage=0&LinkTarget=_top

When I use the K2 web part, the URL of the view flow (which does work) is:

http://<server>/_layouts/tasklist/ViewFlowMain.aspx?ProcessID=89&K2Server=localhost

and then when I click on Process Properties, I get the error previously mentioned.  The URL of that page/frame is:

http://<server>/_layouts/tasklist/ViewFlowReport.aspx?ProcInstID=89&ItemID=0&ItemName=&ItemType=0&ItemInstID=0&ReportPath=

Hope this helps.  Thanks.

Yes, the last two URLs in my previous post were from the K2 Worklist web part.

The Report Server URL setting in the K2 Worklist web part is http://<server>:8000

When I try to change the Report Server URL, I get this message:

Cannot save the property settings for this Web Part. One or more errors have occurred. See below for details.

But there are no other details provided.  However, after going back into the properties of the web part later on, it looks like the change indeed took effect.  However, I still get the error on the view flow as described earlier.

I did find these three errors in the Application event log when I got the error when trying to make the change in the web part:

Okay, the mystery is solved.  Since my report server was on a different port from the SharePoint server, I had to specify this in the web.config file of the SharePoint site:

In the <appSettings> section, add this line:

<add key="ReportServer" value="http://<server>:<port>/ReportServer"/>

and then do an IIS reset.

Thanks to the K2 labs team for solving this problem.
