Hello WebObjects community, this is my first question so don't be too hard on me ;)
Lets say I have a wo:loop in a component...
<wo:loop list = "$dg.displayedObjects" item = "$aItem"> <tr> <td> <wo:string value = "$~timeConsumingCallA()" /> </td> <td> <wo:string value = "$~timeConsumingCallB()" /> </td> <td> <wo:string value = "$~callDependingOn_A_and_B()" /> </td> </tr> </wo:loop>
- Functions timeConsumingCallA() and timeConsumingCallB() are, as their name imply, costly calls.
- Function callDependingOn_A_and_B() depends on the results of the two first functions.
Is there any guarantee that the two function calls (timeConsumingCallA, timeConsumingCallB) will always be called in order and before callDependingOn_A_and_B() so I can set and depend on instance variables $timeConsumingCallA_result and $timeConsumingCallB_result in the callDependingOn_A_and_B() function?
If not, I can see a number of ways I could myself make sure the calls are made in the correct order in straight-Java, but I was wondering if there was a "Wonder/WebObjects" strategy to approach this.
Thanks for your time,
