Extensions to Spring’s FreeMarker macro’s (spring.ftl)

Posted on by

Spring’s FreeMarker macro’s are pretty useful, but there are a couple of things I need from the showErrors macro that simply aren’t there:

  1. Show errors without a HTML tag around them – if you don’t specify a classOrStyle, the showErrors macro will wrap your error message in a <b> tag. If you do, it’ll wrap it in a <span> (understandably)
  2. Pick the tag that surrounds each message – As explained in the first point, you can see we only get the choice of <b> or <span>. What if I wanted to use an <li>? …use the separator? – no good, because unless I write an <#if> statement to check the number of error messages before I call showErrors I’ll end up with redundant <ul>/<ol> and <li>’s in my markup if there aren’t any errors:
    e.g. <ul><li><@spring.showErrors “</li><li>”/></li></ul>
    Which leads me nicely onto the next point:
  3. Show errors in an ordered/unordered list, automatically detecting zero messages and not outputting markup if this is the case
  4. Show errors for multiple bind paths – Spring’s showErrors only shows errors for the currently bound field. However I’ve found that I’ve needed to show errors for 2 or more fields together. This is particularly true of a DOB field where the day/month and year are separate <select>’s
  5. Finally, show errors for multiple bind paths, in an unordered/ordered list

You can download my Spring extensions here: springx.ftl. Inevitably I’ll find more bits and pieces to add and will update them accordingly.

  5. והסתובבה. ומי דיבר בעלה הציץ מאחורי כתפה. – אז ספר לך הכל קסניה נהמה והפנים נעלמו. – איך? – שאלה חדשה נשמעה לאחר ההפסקה. אבל קסניה העמידה פנים שהיא כבר ישנה. באותו ערב היא עטפו את מותני והוא משך אותי אליו וגרם לי להתנתק ממארק. עכשיו הרגשתי את תקיפותו מונחת על בטני התחתונה. שני קשיות שונות מלפנים ומאחור. שני ריחות שונים. שני גופים שונים שרוצים את אותו sratimkhulim.co.il

  9. Great insights on modern access control systems! I’ve noticed a big shift toward cloud-based platforms with mobile credentials and real-time audit trails, which not only tighten security but also simplify compliance security cameras near me
