> Key: WICKET-2812
> URL: https://issues.apache.org/jira/browse/WICKET-2812
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4.5
> Environment: IE6 / FF3.6 / Opera9
> Reporter: Rutger Jansen
> Assignee: Igor Vaynberg
> Fix For: 1.5-M1
>
> Attachments: TextArea.java.patch
>
>
> When the content of a textarea starts with an empty line, this line
> disappears when it is placed in the html.
> This is a known problem with the html textarea element.
> <textarea>test</textarea> will result in the same as:
> <textarea>
> test</textarea>
> Meaning that the first newline in the textarea is ignored. In case of opening
> a page with a textarea with a leading blank line, this line will be removed
> when the form is submitted again.
> See for similar issues in the apache jira STR-1366 and BEEHIVE-1005
> A possible solution is to change the following method in
> org.apache.wicket.markup.html.form.TextArea in something like:
> protected final void onComponentTagBody(final MarkupStream markupStream,
> final ComponentTag openTag) {
> checkComponentTag(openTag, "textarea");
> String value = getValue();
> if (value != null && value.startsWith("\n")) {
> value = "\n" + value;
> } else if (value != null && value.startsWith("\r\n")) {
> value = "\r\n" + value;
> } else if (value != null && value.startsWith("\r")) {
> value = "\r" + value;
> }
> replaceComponentTagBody(markupStream, openTag, value);
> }
