Label Visibility Property in BIRT 4.2.0

kpelzer29

I have a report that contains a label. I also have a report parameter named <em class='bbc'>rep_param1</em>. In the Visibility property of the label, I have checked the <em class='bbc'>Hide Element</em> checkbox, selected the <em class='bbc'>For <span class='bbc_underline'>all</span> outputs</em> radio button, and in the Detail section I have javascript similiar to:<br />
<br />
if (params["rep_param1"].value == 'A' || params["rep_param1"].value == 'B')<br />
{<br />
true;<br />
}<br />
<br />
Why do I get the following error message when I run the report in BIRT 4.2.0 and the value of <em class='bbc'>rep_param1</em> equals 'C'?<br />
<br />
<em class='bbc'>The following visibility expression does not evaluate to a legal boolean value: if (params["rep_param1"].value == 'A' || params["rep_param1"].value == 'B') <br />
{<br />
true;<br />
}</em><br />
<br />
I do not receive this error when I run the same report in BIRT 3.7.0.

Try putting the else{false;} on there, or just removing the if portion and simply having the condition:

params["rep_param1"].value == 'A' || params["rep_param1"].value == 'B'

This will automatically return true or false if the condition is met or not, rather than you specifying.

From the sounds of your error, that should do it.
