Yaytay commented on WW-3553:
----------------------------
As a starting point I've taken the source code for the Property tag and changed
it to have:
Object objectValue = getStack().findValue(value,
throwExceptionOnELFailure);
try {
actualValue = JSONUtil.serialize( objectValue );
} catch( JSONException ex ) {
LOG.error("Could not convert {} to a JSON serialized value: {}",
objectValue, ex);
}
> Provide a tag to enable JSON output to be placed in an output page for any
> expression

> Key: WW-3553
> URL: https://issues.apache.org/jira/browse/WW-3553
> Project: Struts 2
> Issue Type: New Feature
> Components: Plugin - JSON
> Affects Versions: 2.2.1
> Reporter: Yaytay
> Priority: Minor
>
> I frequently need to have JSON included in an HTML page downloaded by the
> client (i.e. not via AJAX).
> This is typically then processed by client-side javascript (often using
> jqGrid).
> There are a few ways that this can be achieved currently, but they are all
> cumbersome and inflexible (requiring code to be written for every thing that
> needs to be expressed in JSON).
> It would be much more convenient to have a tag that could express any OGNL
> expression as JSON.
