Hi,
I am using T 5.3-rc-3 and I am getting the following error message while
submitting any forms in my app:
---
A JSONArray text must start with '[' at character 1 of "[\"save\",
\"save\"]"

What's puzzling is that the form works in a dummy app but fails in the core
(complex) app. This makes me believe that there is something else that is
interfering with tapestry. I've also noticed that if I disable Javascript in
the browser, the submission is successful.
It looks as if:
String raw = request.getParameter(SUBMITTING_ELEMENT_ID);
in Form.isCancelled() is returning a String in double quotes (in my case)
but I can't figure out where this is created.
Has anybody else seen this?
Below is an excerpt:
java class:
....
void onSuccess() {
String uploadDir = context.getRealFile("/").getAbsolutePath() +
"/resources";
File dirPath = new File(uploadDir);
if (!dirPath.exists()) {
dirPath.mkdirs();
}
File copied = new File(uploadDir , file.getFileName());
file.write(copied);
}
tml:
....
<form t:type="form" t:id="upload" clientValidation="none">
<ul>
<li>
<label t:type="label" for="name"/>
<input t:type="textfield" t:id="name" validate="required"/>
</li>
<li>
<label t:type="label" for="file"/>
<input t:type="upload" t:id="file" validate="required"/>
</li>
<li>
<input t:type="submit" value="Upload" t:id="save" />
<input type="button" value="Cancel"/>
</li>
</ul>
</form>
