Description

Dear developers:

I'm sorry that my English level is not very good, maybe this letter does not conform to English writing habits.  I am writing this message to you because maybe I found a frontend bug of griffin.

The version of griffin I am using is 0.6.0.Here are the phenomenon.

When I trying to create new profiling which including a "Regular Expression Detection Count"，I typed my regular expression(^(10|[1-9])$) and submit it successful.

Then I checked the rule just submitted but the regular expression was changed to '^[0-9]

{4}$'，the full expression is as shown bottom，obviously not my wish.
[
{
"id": 560,
"rule": "count(source.desc) AS `desc_regexcount` WHERE source.desc RLIKE '^[0-9]{4}

$'",
"dsl.type": "griffin-dsl",
"dq.type": "PROFILING",
"out.dataframe.name": "desc_regexcount"
},
{
"id": 561,
"rule": "count(source.age) AS `age_nullcount` WHERE source.age IS NULL",
"dsl.type": "griffin-dsl",
"dq.type": "PROFILING",
"out.dataframe.name": "age_nullcount"
},
{
"id": 562,
"rule": "approx_count_distinct(source.id) AS `id_distcount`",
"dsl.type": "griffin-dsl",
"dq.type": "PROFILING"
}
]
 

I read the code of frontend module and hold the opinion that it is a frontend bug.

In the file https://github.com/apache/griffin/blob/master/ui/angular/src/app/measure/create-measure/pr/pr.component.ts at line 312,the regulation expression is written to a "constant" not the one I typed.

 

Thank you for your attention.
