Hi,

What would be the input looks like in this case?

{
“decisionKey”:“TEST_RULE”,
“inputVariables”:[
{
“name”:“input”,
“value”:“val1,val2,val3”
}
]
}

Hi @pardeep131085

In order to create an expression to checks if the String values val1, val2 and val3 are present in the collection named input you can create a rule like this;

Input needs to be a Java Collection or a Json ArrayNode.

Hope this helps.

Thanks @yvo

{
“decisionKey”: “DEC_TABLE”,
“inputVariables” : [
{
“name”:“input”,
“value”:“val1,val2,val3”
}
]
}

This input is working fine,

How we make this comparison case insensitive?

Means this input should also works
{
“decisionKey”: “DEC_TABLE”,
“inputVariables” : [
{
“name”:“input”,
“value”:“VAL1,val2,val3”
}
]
}

For custom logic like this I would suggest creating your own function delegate.
This is not possible with the provided ones.

Thanks
Can you give some idea how should I start writing own delegates?
Any references or examples.

In one of your recent questions I replied referring to the documentation about function delegates.

Did that provide you with enough info or do you need additional help?
