Codeeffects - Cannot load rule on UI that has In Rule Method with more than 255 string parameter value

Question

It seems that CodeEffect library 4.3.2.6 has an issue with rule XML editing ON UI and transformation back from stroage to show it on UI for editing when rule XML has In Rule method call with string parameter that has string value passed in longer than 255 characters.

Is it made intentionally to avoid long rules to be edited on UI or just a bug so someone knows workaround for it? To avoid any side effects from my code I downloaded and used Business Rule code example from codeeffects site Code Effects Demo Projects and opened it in VS2015.

In "Patient.cs" file added following code to

public class Patient 
{
...
// In Rule Method that accepts only one string parameter
[Method("[NumberOfSegments]")]
public int RuleMethod01(
            // explicitly specify maximum string allowed
            [Parameter(ValueInputType.User,Max = 10000)] 
            string val)
        {
            return val.Split(',').Length;
        }

}

On UI(using Ajax controller) I attempted to create rule with long string parameter passed in (in real project I need such long string since it contains unique parameters for In Rule method to use for calculations and cannot rely on the data sources approach that CodeEffects can offer)

Check if [NumberOfSegments] ("1111,2222,33333,4444,55555,6666,777,8888,999,0000,1111,222,333,44444,1231231,123123123,123123123,123123123,123123123,123123123,123123123,123123123,123123123,123132123,123123123,123123123,123123123,123123123,12123123,123123123,123123123,123123123,1231231233") greater than 12

But even that I explicitly specified maximum string length for parameter as 10000 in attribute Parameter UI does not allow me to enter string that has length more than 256 characters. Documentation on CodeEffects site Business-Rules-Data-Types does not mentioned any built-in restrictions and only way to restrict length of the string parameter use Parameter Attribute and its Max property.

Did anyone ran into the issue with such "synthetic" restrictions and can point me to the documentation or any workaround for that? Thank you in advance for the any meaningful suggestions

PS: Just small update - when I manually edited Rule XML file and provided longer string as parameter (e.g. around 500 characters) I could not load it from the XML back to the UI the RuleEditor::Rule::InvalidElements collection contained one element with Hint property value "v122" dont know if its helpful but may be CodeEffects authors can know more about such Hint and what v122 means.

Answer 1

Strings longer than 255 chars (neither property values nor method params) are not supported in Code Effects. v122 is the error number that you get in response. Its original message is "The length of the value of this string element exceeds the maximum allowed limit".
