multiple record update
had the same issue last week after updating to dataassist 2.0.6 and tracked it down to the repeat counter line - yours currently reads:
$RepeatSelectionCounter_1_Iterations = "1";
I believe it should read:
$RepeatSelectionCounter_1_Iterations = "-1";
It was ultimately fixed by deleting the wincache file - (method at common_installation_issues.pdf ) and re-starting dw. It appears there was some legacy code in the wincache file.
I have advised WebAssist and they are looking at issuing a known issues doc
