Question

Maximum length or number of matches of a pattern matching result

Workflow Pattern Matching and Regular Expressions

Hi,

Does anyone know where I can find information on the maximum length of a returned result in the workflow pattern matching activity, or if there is a maximum number of matches limit.

When examining completed instances in workflow (via tokens) it appears that the results have been truncated, but that may be to save space for stored instances.

However, it does seem that it may be truncated at runtime as well based on the results I am getting and i'd like to confirm if that is the case.

thank you,

Ian

Tokens recorded in the instance details are truncated to 3700 characters to save space. There is no practical limit

Thanks Miruna, this guided me to further debug my Pattern Matching configuration. It turns out that the regular expression was incorrect.

I don't have an example handy, but if you're looking at a multi-value token and seeing a few values followed by an ellipsis, you can double click the cell to see more values. As Miruna said, there are a limited number of items stored. Additionally, the token list will only display the first few items that were stored. Double-clicking the cell will bring up the rest of the values.

Thank you - I have now confirmed it is an issue with my regular expression and not data truncation.
