TextTag enhancement, nameprefix, nameproperty, doErrorsExist()
--------------------------------------------------------------

                 Key: STR-3155
                 URL: https://issues.apache.org/struts/browse/STR-3155
             Project: Struts 1
          Issue Type: Improvement
          Components: Tag Libraries
            Reporter: Mark Stricker
            Priority: Minor


This issue depends on the following issue: https://issues.apache.org/jira/browse/VALIDATOR-265

As I want to use the errorStyle attribute for the text tag I wrote my own TextTag class and enhanced it with the two variables nameprefix  and nameproperty. If both exist i build the name with concatenating the two values, otherwise i call the prepareName() method.

<pc:text errorStyle="..." errorKey="..." name="name" property="mobile" nameprefix="sms_" nameproperty="email" />

protected String prepareNamePlusPrefix() throws JspException {
    String res = null;
    if (this.nameprefix == null || 0 == this.nameprefix.trim().length()) {
        res = super.prepareName();
    } else {
        res = this.nameprefix.trim();
        if (this.nameproperty != null) {
            Object valueName = TagUtils.getInstance().lookup(pageContext, name, this.nameproperty, null);
            res += valueName.toString();
        } else {
            res += super.prepareName();
        }
    }
    return res;
}

When validation fails and I add an Error with property "sms_email" this property also has to be checked in the doErrosExist() method:

protected boolean doErrorsExist() throws JspException {
    boolean errorsExist = false;
    if ((getErrorStyleId() != null) || (getErrorStyle() != null) || (getErrorStyleClass() != null)) {
        if (this.nameprefix == null || 0 == this.nameprefix.trim().length()) {
            return super.doErrorsExist();
        }
        String actualName = prepareNamePlusPrefix();

        if (actualName != null) {
            ActionMessages errors = TagUtils.getInstance().getActionMessages(pageContext, 
                GUIConstants.ERRORS_KEY + GUIConstants.PREV);

            errorsExist = ((errors != null) && (errors.size(actualName) > 0));
        }
    }
    return errorsExist;
}
