workflow

Hi again, thanks in adavance for your help. When i need to make a change to the workflow (for example adding a new form or a new field to the form) I have to change the pool version in order to not affect the current projects that are on execution and then I have to deploy the new workflow, but in that case the current projects doesnt take the change. Does exist any way to make the change and the current projects take that change? Because if I use the same number of version, the projects that are on execution are deleted and they don't appear any more, and all the information is lost.

Hi everyone,

First, I'm sorry if I make mistakes but I'm French ;)

I'm here because i've to develop a web tool to create a "tree of knowledge". This tool isn't juste a workflow, it must have a search button to access to a specific "tree" and have the possibility to create web page..

To be more understandable, here an example : I've this problem to solve : my cat seems sick. Graphically, it's what I need to implement on my tool : http://imagik.fr/view-rl/119289

So, tu summary :
