WAM: jsoncpp shows warnings opening applications in log

Close for FF 6.0.4 and GG 7.0.0

Fixes landed in 02a3b06ed9425.

I've just been able to reproduce the exact scenario you reported. It took longer than I expected because it seems your build have a slightly differen Jsoncpp version (1.8.3, while it should be 1.8.4). 1.8.3 version had this line which produces those "warning" messages when trying to parse empty strings (for example).

Just updated (and attached

) the minimal sample project with new sample and solution to get Jsoncpp implementation behaving just like QJson approach when parsing empty strings.

Finally preparing a patch to submit to fix this issue.

@Nick Yamane < Yes, let's fix those cases.

Regarding the "null" string case for `m_groupWindowDesc` variable:

• Basically, we want to serialize (as JSON) a sub-object (obj["windowGroup"] field, among others) into the string variable m_groupWindowDesc;

• In previous Qt-based implementation, even when that field (windowGroup) was not present the result was an empty JSON Object (as string, represented by "{}"), while in the current Jsoncpp-based one it's ending up with "null" string;

The minimal example I've implemented to compare the behavior of QJson and Jsoncpp (attached

) shows we need a special handling for this cases when that field is not present in the JSON object, which seems to be the case for WebApps we're testing.

If you agree @José Dapena Paz, I'll prepare a patch to fix those cases in flounder branch.
