Problem with Debug - downloading file instead of showing in browser

Anonymous 8 years ago in Studio / Output • updated by Gandalf 8 years ago • 3

Hi team

The latest release (1.1.0.55) has a bug when running a micro service, instead of showing up in the browser it downloads a xml or json file, it was working fine on the previous version. I did some debugging, it happens only when a recordset containing data from a store procedure is configured as output (see the attached image). if I click Debug, and then select "View in Browser(F7)", instead of showing it, a xml file is downloaded (see link)
Regards,

Hi Robin


Thanks for coming through to the community. The part of the process you are talking about is handled by your browser. Please check your browser settings:


# If you return a small result set (a few lines of xml) does it still do this?

# If you use a different browser as default does it still do this?


Some browsers (like IE) will not show JSON results as text and will force a save. Others (like Chrome) will only accept a small amount of response data without forcing you to save it.

Executing javascript (question and ideas)

playsted 8 years ago in Server / Execution • updated by Pieter 8 years ago • 6

What javascript execution engine is used? I have having issues with scripts as some functions are not working properly.


Problem 1:

"testString".endsWith("g");

is valid javascript and works with node and browsers. This should return true.


However running this as a script in a workflow results in an error due to it not being a function.


Problem 2:

If I use variables in the script the strings are not escaped.

Variable:

[[testPath]] = "C:\test"

In script:

"[[testPath]]" => "c:est"



Suggestions:


I think it would be very powerful to use node.js as the javascript execution as it is so widely used. Edge.js is a c# library that allows node to easily be executed from .Net. I haven't researched it much but may be an option.


As far as escaping strings you could predefine them all on a javascript object that the script runs in. Instead of using [[varName]] we could just use $ww.varName if we use $ww as the example object that Warewolf populates. This would take care of string escaping problems and even allow complex objects to be manipulated as expected while coding javascript.

Workflow Persistence

playsted 8 years ago in Server / Execution • updated by anonymous 8 years ago • 1

Hello,


Is workflow state persisted? Can long running workflows (for example if waiting for user interaction/approval) be resumed on server restart? I know workflow foundation supports this (if enabled) but didn't see any specifics in documentation.


Thanks

Answer
anonymous 8 years ago

Hi Playsted,


We have moved away from using the Workflow Foundation engine and in doing so we did not have an immediate requirement from any of our customers to support workflow persistence, and so we did not implement it. So at present there is no state persistence in Warewolf, however should the requirement arise in the market then we can implement it.


Thanks
