[REBOL] Re: [VID] Strange problem
Hi Arie, Attachments are stripped with this list. If possible, just send the script in the body of the email, or if it's too large, place it on a website (if you have one) and just show us the URL. -- Carl Read. Hi all, currently I am developing a small application that displays flags from all over the world off a website. There is also a search option, in order to search for (a part of) a countryname. The REBOL/View version I use is 1.2.46.3.1. I have built in some print statements for debugging purposes and to show the problem exactly. Example session: 1. start the app 2. fill out the search field named country-find with the text ur 3. click the Find (next) button 4. change the contents of the search field named country-find to the text ne When you look at the displayed lines, you see (among others): Right after push Find (next) button: global/findstr=(ne) country-find/text=(ne) Apparently global/findstr has changed somewhere between the last hit and the press of the Find (next) button. However, there is only one place where global/findstr is being changed AFAIK! It was my intention that global/findstr would contain the PREVIOUS searchstring. Please see the attached app Any ideas?

[REBOL] Re: [VID] Strange problem
Hi all, trying to solve my problem I found an error in the argument block of the find-country func. Currently it says: search-text /count /ptr /tmpflags but it should be: search-text /local count ptr tmpflags But the problem I posted for in the first place is not solved by this patch. Thanks, Arie -- To unsubscribe from this list, just send an email to [EMAIL PROTECTED] with unsubscribe as the subject.

It is a lack of copy. global/findstr: copy search-text or find-country copy country-find/text Anton.

Hi Anton, that was the old friend copy again, sigh :-[ But still I am very glad that you've made me aware of the problem :-) Many thanks for your help!
