Removing the file attached to workflow (WFM)

We have a process to check the folders and files attached to the workflow, if any file/directory cannot be deployed we need to remove that file from workflow.

I have written pre processor to do this. However the code below is not workking. Any ideas whether I am doing any thing wrong.

Given below snippets of code.

WFMWorkflow execute(WFMWorkflow wfmw, Map<String, String> map) {

WFMFile[] wfmFiles = wfmw.getFiles();

for(int i = 0; i < wfmFiles.length - 1; i++) {

String fileVpath = wfmFiles[i].getFilePath().replace("\\","/");

wfmw.removeFile(new WFMFile(fileVpath, "File removed by WFM"));

}

Also I have to add some default file using addFile funciton as follows. The code adds file successfully as it throws an exception if I try to add it multiple times saying "File is already attached to the workflow". However once the job is initiated, if open user task I dont see the files I have attached. Only I could see the files attached during the job initiation.

I am using the following code for adding file.

try{

wfmw.addFile(new WFMFile(fileVpath, "File added by WFM"));

}catch (WFMException wfme){

logger.error("Exception in PreInitiateProcess:execute():" + wfme);

}

I have seen the API docs and everything looks good.

Appreciate your thoughts.

Environment: TS7 using WFM, OS: Windows

I'm not sure what the actual problem you're having is - but I'll suggest an alternative approach to the one you've taken...

Instead of trying to do this as a preprocessor (presumably called within the custom_instantiation.cfg - yes?) - set this up to be performed in an ExternalTask (presumably the start task, unless you need a CGI task to be first - in which case you may want to write an essentially windowless CGITask to do this so it can run and transition to the next task immediately)

In the code for the ExternalTask you would use the CSSDK code instead of the WFMSDK code - i.e.: getFiles(), attachFiles(), and detachFiles() methods of the CSTask class.

I second ghoti's suggestion.. but I think what might be wrong with your code is that you actually change the file path to something that might not match in the workflow. You already have a handle on the WFMFile object, so why create a new one? Try this instead:

WFMFile[] wfmFiles = wfmw.getFiles();
for (WFMFile f : wfmFiles) {
  // your logic goes here
  wfmw.removeFile(f);
}

Before giving up and trying out the external task, thought I will give a last try with rpoulin's suggestion. But it makes me go crazy with the output I have got. Before raising it as a bug with HP, thought I will take your expert inputs (second eye opinion)

My code:

WFMFile[] wfmFiles2 = wfmw.getFiles();

logger.debug("Number of assets attached to the workflow: " + wfmFiles2.length);

for (WFMFile f : wfmFiles2) {

logger.debug("Removing the file from wfm. File: " + f.getFilePath());

wfmw.removeFile(f);

}

// Recheck

wfmFiles2 = wfmw.getFiles();

logger.debug("Number of assets attached to the workflow: " + wfmFiles2.length);

for (WFMFile f : wfmFiles2) {

logger.debug("File: " + f.getFilePath());

}

Output is as follows ( I have attached only two files while initiating). My comments inline in green.

I wonder if the the WFM instantiation process runs multiple times in a manner similar to the way the WFT instantiation does - that might account for the strange results you're seeing - but they do seem off and you probaby should open a case with HP Support about it.

That being said, you probably won't get any real resolution from them that quickly (unless they know or spot something that we're overlooking) - so you should probably start working on the task-based solution...

How did you even manage to attach the same file twice? That shouldn't be possible. But yeah, looks like a bug to me.

I have tried removing the files as the same method u have tried long back and I was able to remove the files.

The check here is it does not allow removing of all the files. Try attaching 2 or more files and remove only one file and check whether you can remove or not.
