I've seen a bug like this before (in other TW plugins)... which can be
caused by the following typical javascript coding sequence:
------------------
var frank=store.getTiddler("FranksTiddler");
var bob=new Tiddler();
bob.title="BobsTiddler";
... etc
bob.fields=frank.fields;
...
store.saveTiddler(bob.title,...,bob.fields);
------------------
The problem arises from this line:
bob.fields=frank.fields;
...while the intent is to copy the *value* of "frank.fields" into
"bob.fields", the effect is to copy a *reference* to "frank.fields"
into "bob.fields". Thus, both tiddlers will share the same "fields"
data, and any subsequent changes to fields in either tiddler will
appear to be applied to both tiddlers simultaneously.
The correct way to copy the internal values from one *object* to
another is to use the TW core's merge() function, like this:
merge(bob.fields,frank.fields);
which results in two *separate* copies of the field values, so that
changing a value in one tiddler will no longer change it in both
tiddlers.
Of course, the above is just a *possible* cause of the symptoms you
are observing... but perhaps it will help the TeamTasks folks find the
actual error in the code.
