1553984 - CRJ: How to Require Non-empty String Parameter

Symptom

When using the Crystal Reports for Java (CRJ) 2.x to render a report, when prompted for a string parameter, the user can press OK without entering anything in the string field.

Resolution

Use IParameterField.setEditMask() to set the mask to "A*".  This will require at least one alphanumeric character to be entered.

Or, the report itself can be edited to add the requirement for at least one character. Code is then no longer necessary to effect the requirement.
