Skip the next activity in the Workflow

[chandanmb1]

Hi,

I have a workflow process like

Start -> ServiceTask1 -> ServiceTask2 -> ServiceTask3 -> End

While Execution of ServiceTask1 based on some condition i need to Skip ServiceTask2 and jump to Service Task3.
In normal case it has to execute as is.

How to achieve the above scenario ? Is there any API to skip next step in the process.

Hi,

You need to connect ServiceTask1 to both ServiceTask2 and ServiceTask3 and have the conditions on the flows. So depending on which one evaluates to true, the respective flow will be followed in executing the process.
Example Conditions: ${approve==false} for one flow and ${approve==true}

Hello,

We dont have a control to change the workflow.
We need some mechanism to handle it in Java code at runtime. Is it possible to achieve without changing the workflow by Java code @runtime ?

Hi,

Hook to the process parsing (http://activiti.org/userguide/index.html#_hooking_into_process_parsing) and you can change any behaviour.

Is there any sample code which explains bit more clear about process parsing?
It will be much helpful to see the code and then implement.

There is also a 'skipExpression' construct (which isn't documented yet) that can be used to set an expression that determines whether a step in the process needs to be skipped or not.

This looks interesting for me "SkipExpression"
but how to use it ?  Please provide some sample Junit code ?
