Workflow Activity Routing based on Attribute

[maheshkumar]

Hi, I have to decide my workflow path depending on an attribute type, which is having a list of values, Each value will take a separate workflow after choosing it.

I am tried to execute the below code but some how not succesful.

For Routing Two options succesfully executed, while i am using the values in place of String_value its not working.

Soft Attribute Name = CustomerGroup, Dropdown values are HERO/FORD.

if (primaryBusinessObject != null)

{

try

{

com.ptc.core.lwc.server.PersistableAdapter obj = new com.ptc.core.lwc.server.PersistableAdapter(primaryBusinessObject,null, java.util.Locale.US, new com.ptc.core.meta.common.DisplayOperationIdentifier());

obj.load("CustomerGroup");

java.lang.String string_value = (java.lang.String) obj.get("CustomerGroup");

System.out.println("Soft attibute value : " + string_value);

if ( string_value == "HERO" )

{

result = "Route1";

}

else

if( string_value == "FORD" )

{

result="Route3";

}

else

result="Route2";

}

catch ( Exception e )

{

e.printStackTrace();

}

},

Below code executed succesfully,

Soft Attribute Name = CustomerGroup, Dropdown values are HERO/FORD.

if (primaryBusinessObject != null)

{

try

{

com.ptc.core.lwc.server.PersistableAdapter obj = new com.ptc.core.lwc.server.PersistableAdapter(primaryBusinessObject,null, java.util.Locale.US, new com.ptc.core.meta.common.DisplayOperationIdentifier());

obj.load("CustomerGroup");

java.lang.String string_value = (java.lang.String) obj.get("CustomerGroup");

System.out.println("Soft attibute value : " + string_value);

if ( string_value !=null)

{

result = "Route1";

}

else

result="Route2";

}

catch ( Exception e )

{

e.printStackTrace();

}

}

Thanks in advance.

Try .equals() or equalsIgnoreCase()  to compare the values to String values and check if it helps.

string_value.equals("FORD"); string_value.equalsIgnoreCase("FORD");

Try below expression.

if (primaryBusinessObject != null)

{

try

{

com.ptc.core.lwc.server.PersistableAdapter obj = new com.ptc.core.lwc.server.PersistableAdapter(primaryBusinessObject,null, java.util.Locale.US, new com.ptc.core.meta.common.DisplayOperationIdentifier());

obj.load("CustomerGroup");

java.lang.String string_value = (java.lang.String) obj.get("CustomerGroup");

System.out.println("Soft attibute value : " + string_value);

if ( string_value.equals("HERO") )

{

result = "Route1";

}

else

if( string_value.equals("FORD") )

{

result="Route3";

}

else

result="Route2";

}

catch ( Exception e )

{

e.printStackTrace();

}

}

Now, there is no syntax error, but Default "Route2" option is executing. If choose IF condition as null, throwing an error. ATTENSION: null

Thanks

Remember that java is case sensitive, so the case statement string_value.equals("HERO")  means the attribute value shas to be HERO and not Hero etc for it to work.

You can also use equalsIgnoreCase() or if(compareToIgnoreCase("HERO") == 0) ....
