Robot selector and action

[Alex]

i have a few question for the selectors and action (java api)

the blip.first(String arg); is the arg a regular expression or just a
normal string? i tried regular expression \[new\], it matches only \
[new\] and not [new].

and once i get the BlipContentRefs, i tried the delete() method and
then add a gadget, but the specified string is still in the blip and
this cause a infinite loop of onDocumentChangedEvent.

how do i prevent the infinite loop? the delete() method dont seem to
work.

and i have tried using
Map<String, String> restrictions = new HashMap<String, String>();
BlipIterator iterator = new BlipIterator.ElementIterator(blip,
ElementType.GADGET, restrictions, -1);
int start = iterator.next().getStart();
as suggested in http://wave-api-faq.appspot.com/#elementindex

to chk if the gadget exist in the blip, but eclipse complain that
BlipIterator.ElementIterator is not visible.

That is just a normal string. You can do event filtering using regular expressions, but

that is done using a @Capability annotation in Java:

and once i get the BlipContentRefs, i tried the delete() method and
then add a gadget, but the specified string is still in the blip and
this cause a infinite loop of onDocumentChangedEvent.

Can you try just deleting the text first and not inserting the gadget and

determine if that still causes an infinite loop?

  Thanks,

ok thanks,

for blip.first(String arg);
what does it return if the content of the blip does not contains the
arg?
and how do we know if the given arg does not exist in the blip?

currently i am using blip.getContent().contains(arg) before i call
blip.first(arg)
