i am having related issue to attaching locked files. so i thought i add on this.my workflow (wfm) is like this:editor modifies DCR in CCSTD -> submits -> reviewer gets task to approve or reject content -> ...->endthe reviewer wants to preview the attached DCR before he approves. so he would click preview ( which opens up the DCR in read-only mode) then clicks on preview button in the DCR to open up the HTML version. this is where a lock conflict error is triggered and it says that the DCR is locked by the author who last edited the DCR.my workaround is to set the lock of the attached files to the task owner. which seems to resolve the issue but i dont know if it is good idea in case when reviewer doesnt get to the task in a day or two, and the editor needs to work on the DCR again.
