Problem with behaviors' on entry validation

[Paul]

Hi all,

I need to validate format for "My Example Field" during issue creation by a user.

User entry should consists of prefix (always "ABCD") and suffix (a number), e.g. ABCD12345.

The code below, obviously, doesn't work.

Problems:

1. If a user enter any string less than 9 characters, no validation happens; it has to be 9 or more.

2. Doesn't matter what a user enter for a prefix - no validation of prefix at all.

3. For string equal or more than 9 characters, only suffix is validated (characters from 5 to 9).

Code:

import com.onresolve.scriptrunner.runner.util.UserMessageUtil
import com.opensymphony.workflow.InvalidInputException

String field = getFieldByName("My Example Field").getValue()

String prefix = field.substring(0, 4);
String suffix = field.substring(4, 9);

if (!prefix == "ABCD"){
getFieldByName("My Example Field").setError("Incorrect prefix: " + prefix)
}
else if (!suffix.isInteger()){
getFieldByName("My Example Field").setError("Incorrect suffix: " + suffix)
}
else {
getFieldByName("My Example Field").clearError()
}

Any ideas please?

Bump.

It seems as an easy task but it looks like string format validation doesn't work in ScriptRunner?
