New vesion of ODK won't run forms that functioned well before- constraint error

[GoogleCodeExporter]

What steps will reproduce the problem?
1.opening previously working older ODK forms in ODK 1.4.3, recently installed 
from Playstore on 2 newly purchased Android devices
2.Only an error message appears
3.It reads :'bind for /AIC_followup_survey_v1.1/physical_exam/child_height 
contains invalid constraint expression [regrex(^[0-9]+.[0-9]{2})?$)] Couldn't 
understand the expression starting at the point: regrex..."

What is the expected output? What do you see instead?
I expect a fillable form. Instead there is only an error message. Old forms are 
non-functional

What version of the product are you using? On what operating system?
ODK 1.4.3 and Android Jelly Bean

Please provide any additional information below.
Can I install an older ODK version that works?
Have the regrex commands changed?

regrex isn't a valid command. regex (note that there is only one r) is. 

Can you make sure your form has regex and not regrex?

Sorry. That was my typo. the actual code is 'regex' not 'regrex'

Can you attach the form to this issue or e-mail it referencing this issue?

• Added labels: Collect

Attached is an example of our previously functional forms that won't run under 
ODK 1.4.3. If I delete the sections with regex, the forms work fine.
Thanks.

Actually, it failed with ODK Validate for ODK Collect 1.4 rev 1037 and older 
also. In that case, however, the failure was not highlighted in red -- it was 
in blue (at the top of the error report).

Your regex expressions are not well formed -- they need to have two arguments, 
and the regex term needs to be surrounded in quotes (because it is a string).

So lines 96 and 97 were:

      <bind constraint="regex(^[0-9]+(\.[0-9]{2})?$)" nodeset="/HCC_followup_survey_v1.4/demographic_information/child_height" required="true()" type="decimal"/>
      <bind constraint="regex(^[0-9]+(\.[0-9]{1})?$)" nodeset="/HCC_followup_survey_v1.4/demographic_information/child_weight" required="true()" type="decimal"/>

They should be:

      <bind constraint="regex(.,'^[0-9]+(\.[0-9]{2})?$')" nodeset="/HCC_followup_survey_v1.4/demographic_information/child_height" required="true()" type="decimal"/>
      <bind constraint="regex(.,'^[0-9]+(\.[0-9]{1})?$')" nodeset="/HCC_followup_survey_v1.4/demographic_information/child_weight" required="true()" type="decimal"/>
