Right now I have a dataset. Before I would check a NULL value if the with a len() > 0 type of function. This makes it simple because I don't have to add any more columns to my dataset to base the if statement off of. Below is a sample code. These always return true when the variable contains a NULL value.

This worked fine in version 10. After the switch to 11, it exhibits the above behavior.

Any suggestions?

<AMIF EXPRESSION="%len(ds_SeletctResults.Password)% &amp;gt; 0" /> <AMVARIABLE ACTIVITY="set" VARIABLENAME="Password">%Mid(ds_SeletctResults.Password, 1, Len(ds_SeletctResults.Password)-1)%</AMVARIABLE> <AMIF ACTIVITY="end" />

Have you tried the IsNull (and/or IsEmpty) function in place of len?

How would you check for NOT Isnull(%variable%) like this?

Hello Jon,

One workaround to accomplish your goals is to use an "if statement" and compare your data value against an empty variable.

We understand you would like to use the expression better, but this may be used as an alternative.


Task Steps: (Right click, Select All, Copy to copy to the clipboard. Steps can then be pasted into the AutoMate Task Builder)
<AMVARIABLE NAME="varData" VALUE="" /> <AMVARIABLE NAME="varEmpty" VALUE="" /> <AMIF EXPRESSION="%varData% = %varEmpty%" /> <AMSHOWDIALOG MESSAGE="test" /> <AMIF ACTIVITY="end" />

v11.0.2.22:

IF %dataset.columnvalue% = 1 will also return TRUE even if dataset.columnvalue is NULL.

Argh.

Hi Robert,

I wasn't able to reproduce this here. How are you generating the dataset?
