I am trying to start a workflow without attaching it to a document but rather to have the document be created as one of the workflow steps. I learned how to do this through other posts here. So I have added the following to an event in my processdefinition.xml.
All seems fine - it creates the file as I would expect. However when I run my workflow (I start it by selecting the "Start Workflow" option in the MyTasks dashlet). It creates the file, but the log shows no active instances ofthis workflow definition - it does find the definition. Then when I transition to the next step in my workflow, I see the file as an item as expected. When I select it, I am presented with an error saying that "Requested item can not be displayed as it is no longer available". Yet it still shows me the document content despite this error. I am stumped. I also cannot find the document anywhere in my repository. The log file has the following in it.
I have tried the following.
1. adding a variable for bpm_package, and workflow but that actually results in an error the first time I try to access that variable. The lines I added were:
<variable name="bpm_package" access="read,write"/> and
<variable name="workflow" access="read, write"/>
2. Adding document to userhome directory, which btw, I can find when I search the repository, but still results in the same error when I try to open file.
3. I did output the webdavUrl of the document at one point and it was null which makes sense given the log message.
I am wondering if I need to attach the document to the workflow somehow? But I thought by creating the file in the bpm_package, I would be doing that.

I thought i would update my post based on recent findings.
I changed the API I was using from createFile -> createNode.
I then realized that I need to add my newly created node to the bpm_package.
I am using the Share interface and I noticed that my workflow worked fine in Explorer. I then realized that I was not inserting the document into the Share documentLibrary folder but rather into the Share root folder. So I modified the location where the file was being created and the error went away. Here is my new source code:
That works. Now I am attempting to transform my plain text document into a word document but transformDocument() keeps returning null. Any ideas on how to do this differently? The code I was using is as follows.
Thanks!
